App-specific terms

OldFriend

OldFriend is a social habit and games app. It has accounts, and it collects more than our other apps because the features require it.

Account information

• Email address — to create your account, confirm it, and let you sign back in. It is never shown to other users, ever.
• Username and profile photo — visible to other people in the app. That is their purpose.
• Password — stored only as a salted hash by our authentication provider. Nobody, including us, can read it.

Location — including in the background

This is the most sensitive thing we collect, so it gets its own section.

• During a live race or a tracked walk, we record your GPS position continuously — including while the app is in the background or your screen is off. That is the only way to measure a distance you walk with your phone in your pocket. Tracking starts when you start a race or a walk and stops when it ends. It never runs at any other time.
• On a challenge check-in, we attach the coordinates where a photo or video was taken, so the people in that challenge can see the proof is genuine.
• Who sees it: your distance and position during a race are visible to the other people in that race. A check-in's location is visible to people in that challenge. Your location is never shown to strangers, never sold, and never used for advertising.
• You can refuse. Declining location permission disables races and route tracking. Everything else in the app keeps working.

Health and fitness data

If you use the Health tab we collect steps, calories burned, distance, sleep duration, and any height, weight and age you enter to set a goal. On Android, with your permission, we read steps, distance, calories and sleep from Health Connect so figures match what your phone or watch already recorded.

This data is yours. It is used to show you your own progress and to work out the pace your goal needs. It is not shared with other users, not used for advertising, and not sold. Aggregate step counts appear on a race leaderboard only for races you choose to join.

Health Connect access is optional. Declining it leaves every other feature of the app working; only the automatic figures are lost. We do not transfer Health Connect data to any third party, and we do not use it for advertising or for any purpose other than showing you your own activity and progress.

Photos, video and proof

Challenge check-ins and dare forfeits are photos or short videos you record. They are visible only to people in the same challenge or to the friend you dared. Proof media is deleted automatically after 30 days, from both your device and our storage. Settled dares are cleared after 24 hours, unfilmed ones after 72 hours, and unanswered dares after a week.

Messages

Direct messages are encrypted with a key unique to each conversation before they leave your device. We store the encrypted text and cannot read the contents. Reported messages can be reviewed by a moderator, which is the one exception and exists so harassment can be acted on.

Purchases

Subscriptions are handled by the app store. We never see or store your card details — the store tells us only whether a subscription is active. Diamonds, limits and entitlements are calculated on our servers.

Notifications

If you allow them, we store a push token for your device to send reminders, invites and challenge updates. Turning notifications off in your device settings stops them.

Advertising

OldFriend contains no advertising. There is no advertising SDK in the app, no advertising identifier is read, and no data is shared with any advertising network or data broker.

Device permissions

Android and iOS ask for each of these separately, and every one can be refused. What breaks when you refuse is named beside it.

• Camera — to record the photo or video proof for a challenge check-in or a dare.
• Microphone — video proof records sound with the picture. It is only active while you are recording, and we never listen at any other time.
• Photos and videos — so you can submit an existing photo or video instead of recording a new one, and set a profile picture. We read only the files you pick.
• Location, including in the background — races and tracked walks only, as described above.
• Physical activity — to count steps on the device for the Health tab.
• Health Connect (Android) — to read steps, distance, calories and sleep your phone or watch already recorded, so our figures match theirs.
• Notifications — reminders, invites, nudges and challenge updates.

Third-party services

• Supabase — database, authentication and file storage.
• Google Play Billing — subscriptions on Android.
• Firebase Cloud Messaging — delivering push notifications.
• Resend — sending confirmation and account emails.

These are the only third parties OldFriend sends data to, and each receives only what it needs to perform that function. None of them receives data for advertising.

How long we keep things

• Proof photos and videos — 30 days, then deleted automatically.
• Dares — 24 hours once settled, 72 hours if a forfeit is owed, 7 days if unanswered.
• Account data, challenges, posts and messages — until you delete your account.

Deleting your account

You can delete your account from inside the app, under Me. It removes your profile, posts, messages, challenges, proof media and health data. It cannot be undone. See Account Deletion for the full list and for how to request deletion by email if you have lost access to the app.

App-specific terms

Grabbo

Grabbo is a video downloader and editing toolkit for Android. It has no account and no sign-in, and it does not have a profile to attach anything to.

What we collect

• No email, name, contacts, photos or location are collected. There is nothing to register for.
• The links you paste stay on your device. They are sent to the site you are downloading from, as any browser would, and are not sent to us or logged by us.
• Your download history is stored on your phone only. You can clear it at any time from inside the app, and uninstalling removes it.
• The files you download stay on your device. They never pass through our servers.
• Editing happens on your phone. Trimming, merging, compressing, making a GIF or a ringtone and every other tool runs locally. Nothing is uploaded to be processed.

Device permissions

• Storage — to write the file you asked for into your Downloads folder, or into a folder you pick yourself.
• Notifications — to show download progress and tell you when a download has finished.
• Ignore battery optimisation (optional) — Android suspends background work aggressively, which stalls a long download when the screen is off. Declining it keeps everything working; downloads may just pause until you reopen the app.

Advertising

Grabbo contains no advertising. There is no advertising SDK in the app, no advertising identifier is read, and no data is shared with any advertising network or data broker.

Third-party services

None. Grabbo contains no advertising SDK, no analytics SDK, no crash reporter and no billing library. There is no third party in the app to send anything to, which is why the list of what we collect is as short as it is.

Grabbo talks directly to the sites whose links you paste. Those sites have their own privacy policies and see the request as they would see any visitor.

Data retention and deletion

Because Grabbo holds no account, there is nothing on our side to delete. Clearing the download history inside the app, or uninstalling it, removes everything Grabbo has stored.

App-specific terms

Dynoti

Dynoti draws a small island around the camera cutout on your phone and shows what the device is doing there. It has no account and no sign-in, and nothing it reads ever leaves your phone. The one thing it goes online for is its own updates: the version downloaded from this site checks www.aantstudio.com/updates.json for a newer version and, when there is one, downloads the new APK from GitHub, where our downloads are hosted. Those requests carry what any web request does — your IP address and the app’s name and version — and never a notification, a contact, a track or anything else Dynoti has seen. A copy installed from Google Play has no internet permission at all, because Play delivers its updates.

What we collect

• Nothing is collected, transmitted or stored by us. There are no servers, no analytics and no crash reporting.
• Your notifications are read and immediately discarded. Dynoti reads the title, text, icon, colour and action buttons of a notification in order to draw it on the island. That content lives in memory only, is replaced by the next notification, and is gone when the app stops.
• The unread list is held in memory, not on disk. The few notifications the island is currently holding are never written to storage, and restarting your phone clears them.
• Media details are read from the system, not from the app. Track title, artist and album art come from Android’s media session, the same information shown on your lock screen.
• Your settings stay on the phone. Style, calibration, per-app rules and timings are saved in the app’s own private storage and included in your normal Android backup if you use one.

Device permissions

• Notification access — the core permission. It is how Dynoti learns that something arrived and what it says, and it is also how Android grants access to the media session for the now-playing island. Nothing read through it leaves the device.
• Display over other apps — to draw the island on top of whatever you are using. It is the only way to show anything outside the app itself.
• Vibrate — a short tick when the island reacts to a gesture. Can be turned off in Behaviour.
• Run at startup — so the island is there after a reboot instead of waiting for you to open the app.
• Accessibility — optional, and off unless you turn it on — Android reserves the layer above the status bar for accessibility overlays, and enabling this service is the only way an app can draw there. Dynoti’s service does nothing else: it requests no window content, receives no screen text, performs no actions on your behalf and collects nothing. Dynoti is fully functional with it switched off, with the island sitting just below the status bar instead.

Dynoti also has a Reliability screen that opens your phone’s own battery, auto-start and background settings for you. Those are system settings rather than app permissions — Dynoti does not hold them and cannot change them, it only takes you to the right page. Leaving them alone keeps everything working; the island may just be late or absent after the screen has been off for a while.

Dynoti reads the list of apps that can be launched, so the per-app rules screen can show you their names and icons. It uses Android’s limited package-visibility mechanism for this rather than the broad “query all packages” permission, and the list never leaves the phone.

We want to be exact about the accessibility service, because it is a permission that deserves suspicion. It is declared with canRetrieveWindowContent set to false, which means the operating system will not hand it the contents of any screen even if it asked. It exists for one reason — window layering — and it is not used to read, monitor or automate anything. You can revoke it in Android Settings at any time and carry on using the app.

Children

Dynoti is a utility with no social features, no content feed and no data collection, and is not directed at children.

Third-party services

None. Dynoti contains no advertising SDK, no analytics SDK and no billing SDK. Apart from the update check described above, it makes no network requests of any kind.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. Everything Dynoti has stored is your settings, and uninstalling the app removes them. Revoking notification access at any time stops it reading anything immediately.

App-specific terms

69 VPN

69 VPN is a VPN client. It has no account, no sign-in, no analytics and no servers of ours. We do not operate any infrastructure your traffic passes through and we receive nothing from the app. What follows is therefore mostly about the third parties the app talks to on your behalf, because those are the only places your data can go.

What we collect

• Nothing is collected, transmitted or stored by us. There is no backend, no analytics SDK, no advertising SDK and no crash reporting.
• Your browsing is not readable by the app. 69 VPN hands the tunnel to Android and to the OpenVPN engine; it does not inspect, record or store the traffic passing through it.
• Everything the app saves stays on the phone — your settings, your starred servers, the cached server list, the connection log and the profile of the last relay you used. All of it lives in the app’s private storage and is removed when you uninstall.

Third parties the app contacts

These are the only outbound connections 69 VPN makes on its own behalf. Each of them sees your IP address, in the ordinary way any website you visit does.

• VPN Gate (vpngate.net) — the public relay list is downloaded from this academic project at the University of Tsukuba. The request carries no identifier beyond what any HTTP request carries.
• Public relays, when a server cannot be reached directly — some servers are blocked or badly routed on some networks. In that case the app retries the same server through a public relay taken from a freely published list. This is transport only: the VPN tunnel is established end to end with the server and stays encrypted, so the relay carries ciphertext and cannot read or modify your traffic, and cannot see any destination beyond the VPN server’s own address. Your exit country is always the server’s, never the relay’s. Relay lists are fetched from ProxyScrape and a public GitHub list, and each candidate is tested before use.
• VPNBook (vpnbook.com) — the second server list. Two requests per refresh: one for the page carrying the shared account credentials VPNBook publishes openly, and one for a single OpenVPN profile which the app then retargets locally at each of their servers. No account of yours is involved, and nothing about you is sent.
• An archive of past relay lists — older snapshots of the public VPN Gate list are read from a mirror published on GitHub, which is how the app can offer countries that are not in today’s live list. Plain file downloads; nothing about you is sent.
• ipwho.is, with ipinfo.io as a fallback — used only to answer “which country does the internet think I am in?”, before and after you connect. That comparison is what lets you confirm the tunnel is actually carrying your traffic. Whichever one answers sees the address it is answering about, in the ordinary way any website you visit does.
• speed.cloudflare.com, with proof.ovh.net as a fallback — when the app suspects your connection has gone slow it downloads a small fixed-size test file and times it, so the warning it shows is a measurement rather than a guess. A plain download of a public test file, at most once every 45 seconds, and only while traffic is already flowing.

The relay operators — read this part

This is the honest centre of the policy. None of the servers are ours. The VPN Gate ones are donated by volunteers and most declare that they keep connection logs for around two weeks. The VPNBook ones belong to VPNBook, a free donation-supported service operating under its own policy, which we have not audited and do not restate here. Either way the operator can see the same things any VPN operator can: the IP you connected from, when, for how long, and the destinations your traffic was carried to.

69 VPN does not claim a no-logs policy, because it does not own the servers and could not honour one. The app presents the relays simply as countries and does not name their operators in its interface — this policy is where they are named, so that what you are told is in one place and stays accurate. If you need a relay you actually control, import your own .ovpn profile in Settings; the app will use it in place of the public list.

Device permissions

• VPN service — granted through Android’s own consent dialog, which the system shows the first time you connect. It is what allows the app to create the tunnel. Android displays a persistent key icon the whole time a VPN is active.
• Internet and network state — to fetch the server list, measure latency and carry the tunnel.
• Foreground service — Android requires a visible ongoing notification while a VPN is running. That notification shows the live speed, the session length and a disconnect button.
• Notifications — only to display that ongoing status notification. Declining it does not stop the VPN working.
• Installed app list — the split tunnelling screen lists the apps that have a launcher icon, so you can choose which ones use the tunnel. That list is read on the device, shown to you, and never sent anywhere.

The kill switch and always-on VPN are Android settings, not permissions the app holds. Settings has a shortcut that opens the system VPN screen where you turn them on.

Children

69 VPN is not directed at children and collects no personal information from anyone.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. Everything the app has stored is on your phone, and uninstalling it removes all of it. You can clear the connection log from inside the app at any time. Anything a relay operator logged is held by that operator under their own policy, which we have no access to and cannot act on for you.

App-specific terms

EyeBreak

EyeBreak is a Windows program that reminds you to rest your eyes. It has no account and no sign-in, and it goes online for one thing only: keeping itself up to date.

What we collect

• Nothing is collected, transmitted or stored by us. There are no servers, no analytics, no crash reporting and no advertising.
• Your settings stay on your PC. The reminder interval, how much warning you get and how long the break lasts, and whether sounds are on are saved in the Windows registry under your own user account (HKEY_CURRENT_USER\Software\EyeBreak). Nothing else is written there.
• It does not watch what you do. EyeBreak does not read your screen, your keyboard, your files or your other programs. The only thing it listens for is Windows telling it the PC was locked or unlocked, so time away from the screen can count as a break.

What it changes on your PC

• Installation — the program is copied into your own user folder (AppData\Local\Programs\EyeBreak), with a Start menu shortcut and, if you choose, a desktop shortcut. No admin rights are requested.
• Start with Windows — if you leave this ticked, a start-up entry is added for your user account so EyeBreak runs when you sign in. You can switch it off in EyeBreak’s settings.
• Installed apps entry — so that EyeBreak can be removed from Windows Settings like any other program.

Updates

When it starts and every few hours, EyeBreak downloads a small file from www.aantstudio.com/updates.json that lists the newest version. If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it. Those two requests carry what any web request does — your IP address and a line saying the program and its version — and nothing else: no identifier, no settings, nothing about how you use it. Our hosting providers may keep ordinary server logs of the requests.

Links

The settings window has links to this website, this policy, the terms and our email address. They open in your own browser or mail program only when you click them.

Children

EyeBreak is suitable for anyone and collects no personal information from anyone, including children.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. Uninstalling EyeBreak from Settings → Apps → Installed apps removes the program, its shortcuts, its start-up entry and its saved settings.

69 VPN for Windows

69 VPN for Windows is a VPN client. Like the phone app it has no account, no sign-in, no analytics and no servers of ours. We do not operate any infrastructure your traffic passes through and we receive nothing from the program. What follows is mostly about the third parties it talks to on your behalf, because those are the only places your data can go.

What we collect

• Nothing is collected, transmitted or stored by us. There is no backend, no analytics, no advertising and no crash reporting.
• Your browsing is not readable by the program. The tunnel is carried by the OpenVPN engine; 69 VPN does not inspect, record or store the traffic passing through it. It reads only the running byte counters, to draw the live speed graph.
• Everything it saves stays on your PC — your settings, starred servers, the cached server list, what it has measured about each server, imported profiles (including any login you typed for one), and the connection log. These live in %APPDATA%\69 VPN under your own Windows account. The service keeps a short technical log in %ProgramData%\69 VPN; the login and profile it hands to the engine for the current connection sit in a folder only Windows itself and administrators can read, and are deleted when you disconnect.

Third parties the program contacts

These are the only outbound connections 69 VPN makes on its own behalf. Each of them sees your IP address, in the ordinary way any website you visit does.

• VPN Gate (vpngate.net) — the public relay list, published by an academic project at the University of Tsukuba.
• VPNBook (vpnbook.com) — the second server list, and the shared account credentials VPNBook publishes openly on that page. No account of yours is involved.
• An archive of past relay lists on GitHub — older snapshots of the public VPN Gate list, which is how the program can offer countries missing from today’s live list. Plain file downloads.
• The servers themselves — to measure which ones answer and how fast, the program sends each one the opening packet of an OpenVPN session and times the reply. Nothing about you is in it.
• Public relays, when a server cannot be reached directly — the program can retry the same server through a public HTTP relay taken from a freely published list (ProxyScrape and a public GitHub list), each tested before use. This is transport only: the tunnel is established end to end with the VPN server and stays encrypted, so the relay carries ciphertext and sees no destination beyond the VPN server’s own address.
• ipwho.is, with ipinfo.io as a fallback — used only to answer “which country does the internet think I am in?”, before and after you connect.
• This website and GitHub, for updates — the program reads aantstudio.com/updates.json to learn the current version. When a new one is out, the 69 VPN service asks GitHub for the installer’s published SHA-256 checksum, downloads the installer from our GitHub releases page and installs it only if the checksum matches.

The relay operators — read this part

None of the servers are ours. The VPN Gate ones are donated by volunteers and most declare that they keep connection logs for around two weeks; the program shows each server’s declared policy on its row. The VPNBook ones belong to VPNBook, operating under its own policy, which we have not audited. Either way the operator can see what any VPN operator can: the IP you connected from, when, for how long, and the destinations your traffic was carried to. 69 VPN does not claim a no-logs policy it could not honour. If you need a relay you control, import your own .ovpn profile in Settings.

What the installer puts on your PC

• The OpenVPN engine and its TAP network driver, from OpenVPN Inc.’s own signed installer, unless a recent OpenVPN is already installed. A network adapter named “69 VPN” is created for the tunnel.
• The 69 VPN Service, a Windows service that starts the engine with the rights a tunnel needs, so the program itself never runs as administrator. It accepts requests only from programs on this PC and refuses profiles that try to run scripts, load plugins or read other files.
• Firewall rules, only while you use them — the kill switch and IPv6 leak blocking are Windows Filtering Platform rules that exist only while the service is holding them and vanish the moment it stops. Nothing in your saved firewall settings is changed.

Children

69 VPN is not directed at children and collects no personal information from anyone.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. You can clear the connection log from inside the program at any time. Uninstalling from Windows Settings → Apps removes the program, the service, the network adapter, the service’s data and — if 69 VPN installed it — the OpenVPN engine. Your own settings folder in %APPDATA%\69 VPN can be deleted by hand. Anything a relay operator logged is held by that operator under their own policy.

App-specific terms

Tarjuman

Tarjuman is a Windows program that interprets your calls live. It has no account, no analytics and no servers of ours, and we receive nothing from it. Translation is done by Google, using an API key that you create and paste in yourself. That makes Google the one place your meeting audio goes, so most of this section is about what goes to Google and when.

What is sent to Google, and when

• Only while the interpreter is running. Nothing is listened to or sent before you press Start or after you press Stop.
• What your PC plays, for the “client to you” direction. Tarjuman captures the sound Windows sends to your speakers or headphones, leaving out its own voice, and streams it to Google to be translated. This is how it hears the other people in your call. It is everything your PC plays while it runs, not only the meeting, so a video or music playing at the same time is sent too.
• Your microphone, for the “you to client” direction, while that direction is on and “Translate my voice” is selected. When you switch to your real voice (F8), your microphone goes into the call directly and is not sent to Google.
• Where it goes. The audio goes straight from your PC to Google’s Gemini API (generativelanguage.googleapis.com) over an encrypted connection, under your API key. Google sends back the translated speech and the text of what was said and translated. None of it passes through us.
• How Google treats it. Your use of the Gemini API is between you and Google, under the Gemini API Additional Terms of Service. Under those terms, on Google’s free tier Google uses what you send and what it returns to improve its products, and human reviewers may read it. On a paid key it does not. For confidential meetings, turn on billing for your key in Google AI Studio.
• The other people in your call. Their voices are sent to Google for translation. Let them know you are using an interpreter. In some places the law requires their consent.

What stays on your PC

• Your settings (languages, devices, volumes) in %APPDATA%\Tarjuman. Your API key is kept there encrypted with Windows’ own data protection, so it is readable only by your Windows account on this PC.
• No recordings and no transcripts. The captions exist only in the open window and are gone when you close it. Tarjuman does not save audio or text anywhere.
• Other programs’ volume. To turn the client’s original voice down under the translation, Tarjuman lowers the volume of the other programs playing sound while it runs, and puts each one back when you stop. It notes the original levels in %LOCALAPPDATA%\Tarjuman, so they can be restored even if the program is closed unexpectedly. It also reads, but never changes, Windows’ setting for lowering other sounds during calls, so it can tell you if that setting would make the translation quiet.

Other connections it makes

• This website and GitHub, for updates. Tarjuman reads aantstudio.com/updates.json when it starts and every few hours. When a new version is out, it asks GitHub for the installer’s published SHA-256 checksum, downloads the installer from our GitHub releases page, and installs it only if the checksum matches. Never during a meeting.
• Links you click in Settings open in your browser.

Each of these sees your IP address, in the ordinary way any website you visit does. Tarjuman contacts nothing else.

Children

Tarjuman is a tool for work calls. It is not directed at children, and it collects no personal information for us from anyone.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. Uninstalling Tarjuman from Windows Settings → Apps removes the program, your settings and the stored API key, and restores any volume it had lowered. What you sent to Google is held by Google under its own terms; you can delete or restrict your API key at any time in Google AI Studio.

App-specific terms

KeyPop

KeyPop is a Windows program that turns the keyboard into a full-screen toy for babies and toddlers. It has no account and no sign-in, and it goes online for one thing only: keeping itself up to date.

What we collect

• Nothing is collected, transmitted or stored by us. There are no servers, no analytics, no crash reporting and no advertising.
• Key presses are never recorded. While a child is playing, KeyPop catches every key before Windows does, so that shortcuts like the Windows key and Alt + Tab cannot open anything. Each press is turned into a picture and a sound on the screen and then forgotten. Nothing that is typed is saved, and nothing is sent anywhere. When the parent leaves play mode, KeyPop stops catching keys.
• The voice runs on your PC. The letters and animal noises are spoken by the English voice built into Windows, offline.
• Your settings stay on your PC. Whether sound, the voice, letters, animals and mouse effects are on, and the volume, are saved in your own user folder (AppData\Local\KeyPop), together with the working files of Microsoft Edge WebView2, the part of Windows that draws KeyPop’s screen.

What it changes on your PC

• Installation — the program is copied into your own user folder (AppData\Local\Programs\KeyPop), with a Start menu shortcut and, if you choose, a desktop shortcut. No admin rights are requested. KeyPop does not start with Windows.
• Only while a child is playing — KeyPop fills the screen, keeps the mouse on it, keeps the screen from going to sleep, and turns off the keyboard shortcuts that open the Sticky Keys, Filter Keys and Toggle Keys pop-ups. Those shortcuts are switched off for the current session only and are put back the moment play ends; if you have one of those features switched on, KeyPop leaves it alone.
• Installed apps entry — so that KeyPop can be removed from Windows Settings like any other program.

Updates

When it starts, and when play ends if a few hours have passed, KeyPop downloads a small file from www.aantstudio.com/updates.json that lists the newest version. If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it. Those two requests carry what any web request does — your IP address and a line saying the program and its version — and nothing else: no identifier, no settings, nothing about how it is used. Our hosting providers may keep ordinary server logs of the requests.

Links

The home screen has links to this website, this policy, the terms and our email address. They open in your own browser or mail program only when you click them, and never while a child is playing.

Children

KeyPop is made to be played with by young children, under a parent’s supervision. It collects no personal information from anyone, including children: it has no account, no camera or microphone access, no chat, no advertising and no way for a child to send anything out of the program.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. Uninstalling KeyPop from Settings → Apps → Installed apps removes the program, its shortcuts and its saved settings.

App-specific terms

Billu

Billu is a Windows program that puts a cartoon cat on your desktop. It has no account and no sign-in, and it goes online for one thing only: keeping itself up to date.

What we collect

• Nothing is collected, transmitted or stored by us. There are no servers, no analytics, no crash reporting and no advertising.
• Where your windows are, never what is in them. To know where the cat can walk and sit, Billu asks Windows for the position and size of the windows that are open, a few times a second. It never reads, captures or records what those windows show, and it keeps none of this information.
• The mouse pointer. Billu watches where the pointer is so the cat can look at it and chase it. In the Playful and Chaos settings the cat sometimes “catches” the pointer and moves it for a few seconds; pressing any mouse button ends that at once. In Chill it never moves the pointer. Billu does not read the keyboard.
• Your settings stay on your PC. The coat, size, number of cats, mischief level, sound settings and the number of treats given are saved in your Windows registry under HKEY_CURRENT_USER\Software\Billu. If something goes wrong inside the program, a short technical note is written to AppData\Local\Billu\errors.log on your PC. It is never sent anywhere.

What it changes on your PC

• Installation — the program is copied into your own user folder (AppData\Local\Programs\Billu), with a Start menu shortcut and, if you choose, a desktop shortcut. No admin rights are requested.
• Start with Windows — if you leave this ticked, Billu adds itself to your account’s start-up programs and a Task Scheduler task that starts it when you sign in. Untick it in Settings to remove both.
• Installed apps entry — so that Billu can be removed from Windows Settings like any other program.

Updates

A few seconds after it starts, and every few hours after that, Billu downloads a small file from www.aantstudio.com/updates.json that lists the newest version. If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it. Those two requests carry what any web request does — your IP address and a line saying the program and its version — and nothing else: no identifier, no settings, nothing about how it is used. Our hosting providers may keep ordinary server logs of the requests.

Links

The Settings window has links to this website, this policy, the terms and our email address. They open in your own browser or mail program only when you click them.

Children

Billu is suitable for everyone. It collects no personal information from anyone, including children: no account, no camera or microphone, no chat and no advertising.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. Uninstalling Billu from Settings → Apps → Installed apps removes the program, its shortcuts, its start-up entries and its saved settings.

Sukoon

Sukoon is a Windows program: a focus timer in an animated room, with sounds made on your PC. It has no account and no sign-in, and it goes online for one thing only: keeping itself up to date.

What we collect

• Nothing is collected, transmitted or stored by us. There are no servers, no analytics, no crash reporting and no advertising.
• Your tasks, stats and settings stay on your PC. The tasks you type, your focus minutes, sessions and streak, the timer lengths and the sound mix are saved in your own user folder (AppData\Local\Sukoon), together with the working files of Microsoft Edge WebView2, the part of Windows that draws Sukoon’s room and plays its sound.
• The music and sounds are made on your PC. Nothing is streamed and nothing is downloaded to play them.

What it changes on your PC

• Installation — the program is copied into your own user folder (AppData\Local\Programs\Sukoon), with a Start menu shortcut and, if you choose, a desktop shortcut. No admin rights are requested. Sukoon does not start with Windows.
• Only while a focus session is running — Sukoon asks Windows not to go to sleep, so the timer keeps going. The screen can still turn off. When the timer stops, normal power settings apply.
• Notifications — when a session ends, Sukoon shows a Windows notification from its tray icon.
• Installed apps entry — so that Sukoon can be removed from Windows Settings like any other program.

Updates

When it starts, Sukoon downloads a small file from www.aantstudio.com/updates.json that lists the newest version. If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it. Those two requests carry what any web request does — your IP address and a line saying the program and its version — and nothing else: no identifier, no tasks, no stats, nothing about how it is used. Our hosting providers may keep ordinary server logs of the requests.

Links

The Settings panel has links to this website, this policy, the terms and our email address. They open in your own browser or mail program only when you click them.

Children

Sukoon is suitable for students of any age. It collects no personal information from anyone, including children: no account, no camera or microphone, no chat and no advertising.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. Uninstalling Sukoon from Settings → Apps → Installed apps removes the program, its shortcuts and everything it saved, including your tasks and stats.

Zinda

Zinda is a Windows program that plays animated wallpapers behind your desktop icons. It has no account and no sign-in, and it goes online for one thing only: keeping itself up to date.

What we collect

• Nothing is collected, transmitted or stored by us. There are no servers, no analytics, no crash reporting and no advertising.
• The mouse, only over the desktop. So the scenes can react, Zinda reads where the pointer is and whether the left button was pressed, only while the desktop itself is under the pointer. This is passed to the scene on your PC and forgotten. Zinda does not read the keyboard and never captures what is on your screen.
• Which window is in front. To pause when an app fills the screen, Zinda checks the size and position of the window in front, about once a second. It does not look at what that window contains.
• Your settings stay on your PC. The scene, the clock options and the pause options are saved in your Windows registry under HKEY_CURRENT_USER\Software\Zinda; the working files of Microsoft Edge WebView2, which draws the scenes, are kept in AppData\Local\Zinda.

What it changes on your PC

• Installation — the program is copied into your own user folder (AppData\Local\Programs\Zinda), with a Start menu shortcut and, if you choose, a desktop shortcut. No admin rights are requested.
• Your wallpaper is not changed. Zinda shows its scene in the wallpaper layer behind the icons; your own wallpaper setting stays as it is and is shown again when Zinda closes.
• Start with Windows — if you leave this ticked, Zinda adds itself to your account’s start-up programs and a Task Scheduler task that starts it when you sign in. Switch it off in the Zinda window to remove both.
• Installed apps entry — so that Zinda can be removed from Windows Settings like any other program.

Updates

When it starts, Zinda downloads a small file from www.aantstudio.com/updates.json that lists the newest version. If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it. Those two requests carry what any web request does — your IP address and a line saying the program and its version — and nothing else. Our hosting providers may keep ordinary server logs of the requests.

Children

Zinda is suitable for everyone. It collects no personal information from anyone, including children.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. Uninstalling Zinda from Settings → Apps → Installed apps removes the program, its shortcuts, its start-up entries and its saved settings.

Qalam

Qalam is a Windows program for drawing on your screen. It has no account and no sign-in, and it goes online for one thing only: keeping itself up to date.

What we collect

• Nothing is collected, transmitted or stored by us. There are no servers, no analytics, no crash reporting and no advertising.
• Your drawings stay on your PC. What you draw exists only on your screen and is forgotten when you close it. It is saved only when you press Ctrl + S: then a picture of the screen with your drawing goes into PicturesQalam and onto your clipboard, and nowhere else.
• The screen is read only when you ask. Qalam takes a picture of the screen when you save (Ctrl + S) and when you start the zoom, to show it magnified. It does not record the screen, and those pictures stay on your PC.
• Keyboard shortcuts. Qalam registers three shortcuts with Windows (Ctrl + Shift + D, W and Z). It only learns that one of those was pressed; it does not read anything else you type. While the drawing board is open, the keys you press go to the board, for its one-letter tool shortcuts and for the text you type onto it.

What it changes on your PC

• Installation — the program is copied into your own user folder (AppDataLocalProgramsQalam), with a Start menu shortcut and, if you choose, a desktop shortcut. No admin rights are requested.
• Start with Windows — if you choose it, a shortcut to Qalam goes into your Startup folder so the drawing shortcuts work as soon as you sign in. Untick it in Qalam’s window to remove it.
• Installed apps entry — so that Qalam can be removed from Windows Settings like any other program.

Updates

When it starts, Qalam downloads a small file from www.aantstudio.com/updates.json that lists the newest version. If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it. Those two requests carry what any web request does — your IP address and a line saying the program and its version — and nothing else.

Lamha

Lamha is a Windows program that records a part of your screen as a GIF. It has no account and no sign-in, and it goes online for one thing only: keeping itself up to date.

What we collect

• Nothing is collected, transmitted or stored by us. There are no servers, no analytics, no crash reporting and no advertising.
• Recordings stay on your PC. Lamha captures the screen only while you are choosing an area and while a recording is running, and only the area you chose. Recordings are kept in memory until you save them as GIFs in PicturesLamha; nothing is uploaded. If you choose “Save and copy”, the saved file is also placed on your clipboard.
• No sound. Lamha never uses the microphone or records audio.
• Keyboard shortcut. Lamha registers one shortcut with Windows (Ctrl + Shift + G). It only learns that it was pressed; it does not read anything else you type.
• Your settings stay on your PC, in your Windows registry under HKEY_CURRENT_USERSoftwareLamha.

What it changes on your PC

• Installation — the program is copied into your own user folder (AppDataLocalProgramsLamha), with a Start menu shortcut. No admin rights are requested.
• Start with Windows — only if you choose it: a shortcut to Lamha in your Startup folder, so the shortcut key works from sign-in.
• Installed apps entry — so that Lamha can be removed from Windows Settings like any other program.

Updates

When it starts, Lamha downloads a small file from www.aantstudio.com/updates.json that lists the newest version. If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it.

Bijli

Bijli is a Windows program that plays a charging animation when you plug in your laptop, and reminds you about your battery. It has no account and no sign-in, and it goes online for one thing only: keeping itself up to date.

What we collect

• Nothing is collected, transmitted or stored by us. There are no servers, no analytics, no crash reporting and no advertising.
• Battery information stays on your PC. Bijli asks Windows whether the charger is plugged in, how full the battery is and how long it has left, and, once when it starts, how much charge the battery can still hold compared with when it was new. It uses this only to show the animation, the reminders and the Settings window. It is not stored and not sent anywhere.
• No screen capture, no microphone, no keyboard. The animation is drawn on top of your screen. Bijli never reads what is on it, never records sound and does not watch what you type.
• Your settings stay on your PC, in your Windows registry under HKEY_CURRENT_USERSoftwareBijli.

What it changes on your PC

• Installation — the program is copied into your own user folder (AppDataLocalProgramsBijli), with a Start menu shortcut. No admin rights are requested.
• Start with Windows — if you choose it, Bijli puts a shortcut to itself in your Startup folder, so it is running when you plug in.
• Installed apps entry — so that Bijli can be removed from Windows Settings like any other program.

Updates

When it starts, Bijli downloads a small file from www.aantstudio.com/updates.json that lists the newest version. If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it. Those two requests carry what any web request does — your IP address and a line saying the program and its version — and nothing else.

Beamdrop

Beamdrop is a Windows program that moves files and text between your phone and your PC over your own network. It has no account, no cloud and no servers of ours in the middle: files go straight from one device to the other.

What we collect

• Nothing is collected, transmitted or stored by us. There are no analytics, no crash reporting and no advertising.
• Your files never leave your network. When your phone sends a file, it travels over your Wi-Fi directly to Beamdrop on your PC and is saved in the folder you chose (by default Downloads\Beamdrop). Files you share from the PC are read from where they already are, only when a phone you allowed asks for them.
• Texts and links you send between the devices are kept in Beamdrop’s memory while it runs, and are gone when you quit it.
• Devices you allow are remembered on your PC by a name taken from the phone’s browser (for example “iPhone · Safari”), its address on your network and when it was last seen, so they do not have to be allowed again. You can remove any of them at any time.
• Your settings and a short event log (when transfers started and finished, never their contents) stay on your PC, in AppData\Roaming\Beamdrop.

Who can connect

Beamdrop only answers devices on your own local network. A phone needs the code from the QR code on your screen to connect, and unless you turn it off, you approve each new device on the PC once before it can send or receive anything. The phone keeps a small cookie so it is recognised next time; it holds nothing but a random identifier.

What it changes on your PC

• Installation — the program is copied into your own user folder (AppData\Local\Programs\Beamdrop) with a Start menu shortcut. No admin rights are requested.
• Windows Firewall — Windows asks the first time whether Beamdrop may be reached on your network. If you use “Fix Windows Firewall” in the app, it adds one rule allowing Beamdrop, after Windows asks for your permission.
• Start with Windows — only if you turn it on.

Updates

When it starts, and every few hours while it runs, Beamdrop downloads a small file from www.aantstudio.com/updates.json that lists the newest version. If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it. Those requests carry what any web request does — your IP address and a line naming the program — and nothing else.

Children

Beamdrop collects no personal information from anyone, including children.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. Uninstalling Beamdrop removes the program, its settings and the list of allowed devices. Files you received stay in your folder until you delete them.

Deskpad

Deskpad is a Windows program that lets a phone on your own network control your PC: move the pointer, type, press media keys and, if you allow it, see the PC’s screen. It has no account, no cloud and no servers of ours in the middle.

What we collect

• Nothing is collected, transmitted or stored by us. There are no analytics, no crash reporting and no advertising.
• What you type and do is not recorded. Touches, key presses and text travel from the phone straight to Deskpad on your PC, are performed there, and are not saved or logged.
• The screen view is a live video sent directly from your PC to your phone over your network. It is never recorded, saved or sent anywhere else, and it only runs while a phone you allowed has the Screen tab open. You can switch screen view off entirely in Deskpad’s settings.
• Devices you allow are remembered on your PC by a name taken from the phone’s browser (for example “iPhone · Safari”), its address on your network and when it was last seen. You can remove any of them at any time.
• On the phone, Deskpad keeps a small cookie so the phone is recognised next time (it holds a random identifier and nothing else) and your touchpad speed in the browser’s own storage.
• Your settings and a short event log (which phone connected and when, never what was typed) stay on your PC, in AppData\Roaming\Deskpad.

Who can connect

Deskpad only answers devices on your own local network. A phone needs the code from the QR code on your screen, and unless you turn it off, you approve each new device on the PC before it can do anything.

What it changes on your PC

• Installation — the program is copied into your own user folder (AppData\Local\Programs\Deskpad) with a Start menu shortcut. No admin rights are requested.
• Windows Firewall — Windows asks the first time whether Deskpad may be reached on your network. “Fix Windows Firewall” in the app adds one rule allowing Deskpad, after Windows asks for your permission.
• Start with Windows — only if you turn it on.

If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it. Those requests carry what any web request does — your IP address and a line naming the program — and nothing else.

Paperwork

Paperwork is a Windows program for working with PDFs and pictures: merging, reordering, signing, splitting, shrinking and converting them. It does all of it on your own PC. It has no account, and it goes online for one thing only: keeping itself up to date.

What we collect

• Nothing is collected, transmitted or stored by us. There are no servers, no analytics, no crash reporting and no advertising.
• Your files never leave your PC. Paperwork reads the files you open, works on them in memory, and writes the results only where you choose to save them. It does not change the files you opened unless you choose to save over them.
• Signatures. If you leave “Remember on this PC” ticked, the signature you drew or typed is kept as a picture in Paperwork’s settings on your PC (up to eight), so you can use it again. You can forget any of them from the signature window.
• Your settings stay on your PC, in AppData\Roaming\Paperwork: the folders you last used, your choices and a short event log (for example “saved a PDF”, never what was in it).

What it changes on your PC

• Installation — the program is copied into your own user folder (AppData\Local\Programs\Paperwork) with a Start menu shortcut. No admin rights are requested.
• “Open with” — Paperwork adds itself to the “Open with” list for PDFs, PNGs and JPGs. It does not take over your default PDF reader. Uninstalling removes it.

Updates

When it starts, and every few hours while it runs, Paperwork downloads a small file from www.aantstudio.com/updates.json that lists the newest version. If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it. Those requests carry what any web request does — your IP address and a line naming the program — and nothing else.

Children

Paperwork collects no personal information from anyone, including children.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. Uninstalling Paperwork removes the program, its settings and any signatures it remembered. Files you saved stay where you saved them.

Netwarden

Netwarden is a Windows program that shows the devices on your own local network and tells you when a new one joins. It has no account and no servers of ours, and it goes online for one thing only: keeping itself up to date.

What we collect

• Nothing is collected, transmitted or stored by us. There are no analytics, no crash reporting and no advertising.
• What it learns about your network stays on your PC. To find devices, Netwarden sends ordinary network messages to addresses on your own local network: a ping, the questions Windows and other devices use to ask for a name, a search for devices that describe themselves (UPnP), and a check of which common services answer. It never tries to log in to any device and never reads anything sent between your devices.
• What it keeps, in AppData\Roaming\Netwarden on your PC: for each network, the devices it has seen (their addresses, hardware addresses, makers, names and when they were seen), the names, notes and “mine” marks you add, the recent activity list, your settings and a short event log.

What it changes on your PC

• Installation — the program is copied into your own user folder (AppData\Local\Programs\Netwarden) with a Start menu shortcut. No admin rights are requested.
• Background watch — while it is running, Netwarden repeats its check every few minutes (you choose how often, or turn it off). Start with Windows only if you turn it on.

Updates

When it starts, and every few hours while it runs, Netwarden downloads a small file from www.aantstudio.com/updates.json that lists the newest version. If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it. Those requests carry what any web request does — your IP address and a line naming the program — and nothing else.

Children

Netwarden collects no personal information from anyone, including children.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. “Forget this device” removes one device from its memory; uninstalling Netwarden removes the program and everything it remembered.

App-specific terms

Keepsafe

Keepsafe is a Windows program that backs up folders you choose to a drive or folder you choose. It has no account, no cloud and no servers of ours: your backup lives only where you put it, and Keepsafe goes online for one thing only, keeping itself up to date.

What we collect

• Nothing is collected, transmitted or stored by us. There are no analytics, no crash reporting and no advertising.
• Your files go only to your backup drive. Keepsafe reads the folders you chose and writes copies, and a list of what was in them at each backup, to the destination you chose. Nothing is sent anywhere else.
• Encryption. If you set a password, everything Keepsafe writes to the backup is encrypted with AES-256 under a key derived from your password. The password itself is never stored. So that scheduled backups can run without asking, the derived key is kept on your PC, encrypted by Windows for your user account.
• On your PC, in AppData\Roaming\Keepsafe: your backup plan (folders, destination, schedule), the history of recent backups and a short event log. Uninstalling removes them; it never touches your backups.

What it changes on your PC

• Installation — the program is copied into your own user folder (AppData\Local\Programs\Keepsafe) with a Start menu shortcut. No admin rights are requested.
• Restoring — Keepsafe writes restored files where you ask. Restoring to the original place never overwrites a file that is there: the restored copy gets the date in its name.
• Start with Windows — if you choose it during setup or in Settings.

Updates

When it starts, and every few hours while it runs, Keepsafe downloads a small file from www.aantstudio.com/updates.json that lists the newest version. If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it. Those requests carry what any web request does — your IP address and a line naming the program — and nothing else.

Children

Keepsafe collects no personal information from anyone, including children.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. Your backups stay on your drive until you delete the Keepsafe folder on it; old versions are thinned out automatically as described on the Keepsafe page.

Spacewise

Spacewise is a Windows program that shows what takes up space on your drives, finds duplicate files and clears temporary files. It works entirely on your PC. It has no account, and it goes online for one thing only: keeping itself up to date.

What we collect

• Nothing is collected, transmitted or stored by us. There are no servers, no analytics, no crash reporting and no advertising.
• What it reads. To add up a drive, Spacewise reads the names, sizes and dates of the files and folders you ask it to scan. To find duplicates it reads the contents of files of 1 MB and more, only to compare them with each other. Nothing it reads is saved or sent anywhere; the results are forgotten when you close it.
• What it deletes. Only what you choose. Files and folders you remove go to the Windows Recycle Bin. The cleanup removes temporary files older than a day, browser caches and crash reports; old installers go to the Recycle Bin, and the Recycle Bin is emptied only if you tick it.
• A short event log (for example “scanned a drive, so many files”) is kept in AppData\Roaming\Spacewise.

What it changes on your PC

The program is copied into your own user folder (AppData\Local\Programs\Spacewise) with a Start menu shortcut. No admin rights are requested.

Updates

When it starts, Spacewise downloads a small file from www.aantstudio.com/updates.json that lists the newest version. If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it. Those requests carry what any web request does — your IP address and a line naming the program — and nothing else.

Shoebox

Shoebox is a Windows program that sorts your photos and videos into folders by the date they were taken, and finds copies, near-identical shots and screenshots. It works entirely on your PC. It has no account, and it goes online for one thing only: keeping itself up to date.

What we collect

• Nothing is collected, transmitted or stored by us. There are no servers, no analytics, no crash reporting and no advertising. Your photos are never uploaded.
• What it reads. In the folders you choose, Shoebox reads each photo’s and video’s name, size and dates, and the details stored inside it: the date taken, and the make and model of the camera or phone. To find exact copies it reads the contents of files of the same size, only to compare them with each other. To find look-alikes it asks Windows for a small thumbnail of each photo and compares those. None of this is saved or sent anywhere; it is forgotten when you close Shoebox.
• What it remembers. The folders you chose, where sorted photos go and your options are kept in AppData\Roaming\Shoebox, with a short event log (for example “organized so many files”). Each organize run also writes a small record file, starting with .shoebox-, inside the folder you sorted into; it lists which file went where, so the run can be undone.
• What it changes. Only what you ask for: copies or moves photos into the folder you chose, and moves photos you remove to the Windows Recycle Bin.

What it changes on your PC

The program is copied into your own user folder (AppData\Local\Programs\Shoebox) with a Start menu shortcut. No admin rights are requested.

Updates

When it starts, Shoebox downloads a small file from www.aantstudio.com/updates.json that lists the newest version. If a newer one exists it downloads the installer from GitHub, where our downloads are hosted, and runs it. Those requests carry what any web request does — your IP address and a line naming the program — and nothing else.

Children

Shoebox collects no personal information from anyone, including children.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. Uninstalling Shoebox removes the program, its settings and its log. Your photos, and the record files next to sorted photos, stay where they are.

App-specific terms

Hue Hunt

Hue Hunt is a daily colour game for Android: you find something that matches the day’s colour with your camera. It has no account and no advertising, and nothing about you is collected by us.

What it uses

• Camera. While you hunt, the app looks at the live preview and works out the average colour inside the ring. No photo or video is ever saved or sent anywhere; when you snap, only that colour code and your score are kept.
• Notifications (optional). One reminder a day naming the day’s colour, if you haven’t played yet. Switch it off in Settings. “Start at boot” only re-schedules that reminder after a restart.
• What it keeps, on the phone. For each day played: the colour codes you snapped and their scores. Plus your practice count and best score.

Sharing

When you tap Share, Hue Hunt makes a picture of your result card and hands it, with a line of text, to the app you choose. Nothing is shared unless you do it.

Updates

The copy downloaded from this site checks www.aantstudio.com/updates.json for a newer version of Hue Hunt. If there is one, it downloads the new APK from GitHub, where our downloads are hosted, and hands it to Android’s installer, which asks you to confirm. Those requests carry what any web request does — your IP address and a line naming the app — and nothing else. This is the only reason the app has internet access.

Children

Hue Hunt collects no personal information from anyone, including children.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. Uninstalling Hue Hunt, or clearing its storage in Android’s app settings, removes everything it kept.

App-specific terms

Scrollmeter

Scrollmeter measures how far you scroll in other apps, in metres. It has no account and no advertising, and nothing it measures leaves your phone.

The accessibility service

Android only tells an app how far other apps scroll through an accessibility service, so Scrollmeter has one, which you switch on yourself in Accessibility settings. It is declared to receive one kind of event — “a view scrolled” — and has the ability to retrieve window content switched off. Each event it receives carries the name of the app that scrolled and how far it moved. It cannot see text, images, notifications or anything you type, and it takes no action on your behalf.

What it keeps, on the phone

• Metres scrolled per app per day, for the last 90 days.
• A running lifetime total and the date you started.
• Your daily limit, units and alert setting.

To show app names and icons it asks Android about apps that have a launcher icon; that list is not stored or sent.

Notifications

At most one a day, when you pass the daily limit you set. Switch it off in Settings.

Updates

The copy downloaded from this site checks www.aantstudio.com/updates.json for a newer version of Scrollmeter. If there is one, it downloads the new APK from GitHub, where our downloads are hosted, and hands it to Android’s installer, which asks you to confirm. Those requests carry what any web request does — your IP address and a line naming the app — and nothing else. This is the only reason the app has internet access.

Voice Type

Voice Type finds your vocal range by listening while you sing. It has no account and no advertising, and no sound ever leaves your phone.

What it uses

• Microphone. Only on the range test, the note game and the live pitch screen, and only while they are open. The sound is analysed as it arrives to find the note you are singing, then thrown away. Nothing is recorded or saved.
• What it keeps, on the phone: your lowest and highest note from the last test.

Sharing

When you tap Share, Voice Type makes a picture of your result card and hands it to the app you choose. Nothing is shared unless you do it.

Updates

The copy downloaded from this site checks www.aantstudio.com/updates.json for a newer version of Voice Type. If there is one, it downloads the new APK from GitHub, where our downloads are hosted, and hands it to Android’s installer, which asks you to confirm.

App-specific terms

Receipts

Receipts turns your screen time into a receipt. It has no account and no advertising, and the receipt is worked out entirely on your phone.

Usage access

You grant Receipts “Usage access” in Android’s settings. That lets it read the record Android already keeps of which apps were in the foreground and when, and when the phone was unlocked and the screen turned off. It cannot see anything you do inside an app. Receipts reads that record each time you open it to print a receipt, and does not store it.

To show app names it asks Android about apps that have a launcher icon, and about home-screen apps so that time on the home screen is left off the receipt. Neither list is stored or sent.

Sharing

When you tap Share, Receipts makes a picture of the receipt and hands it to the app you choose. That picture lists app names and times, so look before you post. Nothing is shared unless you do it.

Updates

The copy downloaded from this site checks www.aantstudio.com/updates.json for a newer version of Receipts. If there is one, it downloads the new APK from GitHub, where our downloads are hosted, and hands it to Android’s installer, which asks you to confirm. Those requests carry what any web request does — your IP address and a line naming the app — and nothing else. This is the only reason the app has internet access.

Backwards

Backwards is the reverse singing game: record a phrase, play it in reverse, copy it, and flip your copy back. It has no account and no advertising.

What it uses

• Microphone. Only while you press record, for up to six seconds at a time.
• Your clips. The current round’s two recordings are held in the app’s memory while you play. They are replaced when you start another round and are not kept after you close the app. The app keeps only your best score and how many rounds you have played. It does not back anything up to the cloud.

Sharing

“Share picture” sends an image of your score card; “Share sound” saves the original clip and your flipped copy as one audio file in the app’s private cache and hands it to the app you choose. Nothing is shared unless you do it.

Updates

The copy downloaded from this site checks www.aantstudio.com/updates.json for a newer version of Backwards. If there is one, it downloads the new APK from GitHub, where our downloads are hosted, and hands it to Android’s installer, which asks you to confirm. Those requests carry what any web request does — your IP address and a line naming the app — and nothing else. This is the only reason the app has internet access.

Children

Backwards collects no personal information from anyone, including children.

Data retention and deletion

There is nothing on our side to delete, because nothing reaches us. Uninstalling Backwards, or clearing its storage in Android’s app settings, removes everything it kept.

App-specific terms

Tunecode

Tunecode turns short messages into tunes and reads them back from sound. It has no account and no advertising, and nothing you type or hear is sent to us.

What it uses

• Microphone. Only while listening is switched on, on the Listen screen. Sound is analysed as it arrives to find tunes and then thrown away; nothing is recorded or saved.
• Audio files you choose. When you share a voice note or file to Tunecode, or pick one, it reads that file to find a tune. The file is not copied or kept.
• Messages. What you type and what you read are kept in memory while the app is open, and forgotten when it closes.

Sharing

“Send tune” saves the tune as a sound file in the app’s private cache and hands it to the app you choose. Anyone who receives the tune can read the message in it with Tunecode, unless you scrambled it with a code — and the scramble is for fun, not security.
