The rules, made readable

Terms of Use

The practical agreement behind your Coach.AI account, training guidance and subscription.

Last updated: 3 September 2026

These Terms of Use (“Terms”) are the agreement between you and FOP Serhii Hrynishyn, an individual entrepreneur registered in Ukraine (“we”, “us”), for the Coach.AI mobile app and this website (together, “the App”). By creating an account or using the App, you accept these Terms. If you do not accept them, do not use the App.

These Terms also serve as the end user licence agreement for the App.

1. Eligibility

You must be at least 16 years old to use Coach.AI, and healthy enough to take part in strength training. By using the App you confirm both.

2. Licence

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the App on devices you own or control, for your own non-commercial use. You may not copy, resell, sublicense, reverse-engineer, or redistribute the App or its content, or use it to build a competing service.

3. Your account

• Provide accurate information — your plan is calculated from it, and wrong data produces unsafe loads.
• Keep your credentials to yourself; you are responsible for activity on your account.
• One account per person.
• You can delete your account at any time in the App’s settings.

4. Acceptable use

Do not use the App unlawfully; do not attempt to break, probe or overload it; do not automate or resell access to the AI features; do not upload content that is illegal or that infringes someone else’s rights. We may suspend or terminate accounts that break these rules.

5. AI-generated content

Programs, adjustments and coach replies are generated by an AI model from the data you supply. They can be imprecise, incomplete or unsuitable for your situation. Use your own judgement, adapt loads to how you actually feel, and never treat the App’s output as medical, nutritional or diagnostic advice. You remain responsible for what you do in the gym.

6. Free features and Premium

Part of Coach.AI is free: you can build your first plan and train your first week without paying. Premium unlocks ongoing AI-generated weeks built from your logs, Custom plans, Quick workouts after the first week, and full editing.

Subscriptions

• Premium is offered as a monthly or an annual auto-renewing subscription. An annual plan may include a free trial where the store offers one.
• Payment is charged to your Apple ID or your Google account at confirmation of purchase.
• The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends.
• Manage or cancel your subscription in your store account settings — Apple or Google Play. Deleting the App does not cancel a subscription.
• Each billing period includes an allowance of AI generations. The allowance resets at the start of each period; unused generations do not carry over.
• If a free trial is offered and you subscribe before it ends, the unused part of the trial is forfeited.
• Prices may change; we will tell you before a change takes effect, and a price increase applies only after you consent where the store requires it.

Refunds

Purchases are processed by Apple and Google, not by us, so refunds are handled under their policies. Contact the store that took the payment. If something in the App is broken, write to us first — we would rather fix it.

7. Availability and changes

We improve the App continuously and may add, change or remove features. We aim to keep the service available but cannot guarantee uninterrupted operation; maintenance, store policies or third-party outages may interrupt it.

8. Intellectual property

The App, its design, its exercise library, its texts and its underlying logic belong to us. The training data you enter belongs to you; you grant us only the permission needed to store it and to run the features you use.

9. Termination

You may stop using the App and delete your account at any time. We may suspend or terminate access if you breach these Terms or use the App in a way that endangers the service or other users. Deleting your account deletes your data as described in the Privacy Policy.

10. Disclaimers and liability

The App is provided “as is” and “as available”, without warranties of any kind to the extent permitted by law. We are not liable for injuries, health consequences, lost results, lost data or indirect damages arising from your use of the App or from following its recommendations. Nothing in these Terms limits liability that cannot be limited by law, including liability for death or personal injury caused by negligence, or your statutory consumer rights.

11. Changes to these Terms

If we change these Terms, the new version appears on this page with a new “last updated” date, and material changes are announced in the App. Continuing to use Coach.AI after a change means you accept it.

12. Additional terms for apps downloaded from the Apple App Store

These terms apply if you obtained the App from Apple’s App Store:

• This agreement is concluded between you and us only, not with Apple. We, not Apple, are solely responsible for the App and its content.
• The licence granted in section 2 is limited to a non-transferable licence to use the App on any Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions.
• Apple has no obligation whatsoever to provide any maintenance or support services for the App.
• In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the App to you. To the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to the App.
• We, not Apple, are responsible for addressing any claims relating to the App, including product liability claims, any claim that the App fails to conform to a legal or regulatory requirement, and claims arising under consumer protection, privacy or similar legislation.
• We, not Apple, are responsible for the investigation, defence, settlement and discharge of any third-party claim that the App infringes that third party’s intellectual property rights.
• You represent that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
• Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, will have the right to enforce them against you.
• Questions, complaints or claims about the App should be sent to serjgrey.3d@gmail.com.

13. Additional terms for apps downloaded from Google Play

If you obtained the App from Google Play, your use is also subject to the Google Play Terms of Service, and purchases and refunds are handled by Google under those terms.
