Terms of Use

These terms cover aantstudio, this website, and every app we publish. General terms apply to all of them; each app then has its own section.

Last updated · 19 August 2026

These terms describe how our apps actually work. They have not been reviewed by a lawyer — have a solicitor check them before relying on them in a specific jurisdiction.

1. Acceptance of terms

By accessing or using this website or any app published by aantstudio, you agree to be bound by these terms. If you do not agree, please do not use them.

2. Licence to use

We grant you a personal, non-exclusive, non-transferable licence to use our apps on devices you own or control, for your own purposes.

3. Your responsibilities

You are responsible for keeping your account credentials confidential and for activity that happens under your account, and you agree to give accurate information when registering. You must be old enough to use the app under the laws where you live.

App-specific

OldFriend

Challenge participation and prohibited content

When creating or participating in challenges, you agree not to post:

  • Dangerous challenges: content that encourages physical harm, illegal acts, or reckless behaviour.
  • Prohibited content: nudity, graphic violence, harassment, or hate speech.
  • Fake proof: fraudulent, stolen or reused images or videos submitted to falsify challenge completion.

The full rules are in our Community Guidelines.

Your content

You retain ownership of the content you submit, including proof submissions. By submitting content you grant us a worldwide, non-exclusive licence to use, display and distribute it within the context of operating the app — showing your check-in to the people in your challenge, and nothing beyond that.

Subscriptions, diamonds and refunds

OldFriend Pro is a recurring subscription billed by the app store you installed from, not by us. It renews automatically until you cancel, and you cancel through that store — Google Play or the App Store — not inside the app. Refunds are handled by the store under its own policy; we cannot grant or refuse one on their behalf.

Diamonds and the cosmetic items bought with them have no monetary value, cannot be exchanged for money, and are lost if you delete your account. Nothing bought with diamonds affects the outcome of a race, a dare or a spin — every result is decided on our servers and cannot be purchased.

Physical activity disclaimer

Challenges, races and walks involve physical activity that you undertake at your own risk. OldFriend is not a medical service and the Health tab is not medical advice. Consult a doctor before starting any new physical routine.

Account suspension

We may suspend or terminate an account for violations of these terms or the Community Guidelines.

App-specific

Grabbo

How you use it is your responsibility

Grabbo is a general-purpose tool that saves a file you point it at. You are responsible for having the right to download what you download. Only save content you own, content published under a licence that permits it, or content the rights holder has allowed you to keep. Respect the terms of the sites you use and the copyright law where you live. We do not host, provide, index or supply any of the content you download.

Availability

Grabbo depends on third-party sites we do not control. A site may change, block downloading, or stop working at any time, and we do not guarantee that any particular site or link will work. No refund or remedy arises from a site becoming unavailable.

Free tier, Pro and ads

Downloading is free and stays free. The editing tools have a daily free allowance — a few runs of each tool per day, which resets at your local midnight. Grabbo Pro removes those allowances and raises the output limits.

Pro is billed by Google Play, not by us. The price and renewal terms are shown by Play before you buy, and you cancel through Play rather than inside the app. Refunds are handled by Play under its own policy; we cannot grant or refuse one on their behalf.

The app ships with an advertising SDK that is currently switched off — no ads are shown in the build you can install today. If that changes, it will be stated here and in the privacy policy first.

General acceptable use

Across all our apps, you agree not to:

  • Use them for anything unlawful, or to harm or harass anyone.
  • Attempt to break, overload, reverse-engineer or gain unauthorised access to our systems.
  • Use them to distribute malware, spam, or unauthorised commercial promotion.

Intellectual property

Except for user-generated content, all intellectual property rights in our apps and this website belong to aantstudio. You may not copy, modify or distribute them without written permission.

Disclaimer of warranties

Our apps and this website are provided "as is" and "as available", without warranties of any kind, whether express or implied, to the fullest extent permitted by law.

Limitation of liability

To the fullest extent permitted by law, we are not liable for any indirect, incidental, special or consequential damages arising from your use of our apps or this website, including injuries sustained while attempting physical challenges.

Termination

You may stop using our apps at any time and delete your account. We may suspend or terminate access for a breach of these terms.

Changes to these terms

We may update these terms. The date at the top changes when we do, and significant changes are announced in the app they affect.
