Terms of Use
These terms are an agreement between you and Alp Kaan Özgül ("we", "us"), the developer of MuscleMaxer (the "App"). By creating an account or using the App you agree to them and to our Privacy Policy. If you don't agree, don't use the App.
1. Who can use MuscleMaxer
You must be at least 13 years old. If you are under 18, or under the age of majority where you live, a parent or guardian must agree to these terms for you. You are responsible for keeping your password safe and for everything that happens under your account.
2. Health and safety
MuscleMaxer is not medical advice. Workouts, plans, heart-rate zones, recovery scores, calorie estimates and rep counts are for general fitness information only. They can be inaccurate. Talk to a doctor before starting a new exercise programme, especially if you have a medical condition, an injury, or are pregnant. Stop exercising and get help if you feel pain, dizziness or shortness of breath. You exercise at your own risk.
3. The AI coach
- The coach's replies, plans and daily guidance are generated by artificial intelligence (DeepSeek and Google Gemini). They can be wrong, incomplete or not suitable for you. Use your own judgement and follow the health and safety section above.
- The coach only works if you allow it. When you do, your messages and the relevant parts of your profile and training history are sent to those AI providers to generate replies, as described in the Privacy Policy.
- You can turn this off at any time in Settings. The rest of the App keeps working without it.
- Don't enter information into the coach that you don't want processed this way.
4. Subscriptions
- MuscleMaxer is free to use. Premium and Premium Plus are optional auto-renewing subscriptions, sold monthly or yearly at the prices shown in the App.
- Payment is charged to your Apple ID when you confirm the purchase.
- Your subscription renews automatically unless you turn off auto-renew at least 24 hours before the end of the current period. Your account is charged for renewal within the 24 hours before the period ends.
- You can manage or cancel your subscription in your Apple ID settings (Settings → your name → Subscriptions). Cancelling stops the next renewal; you keep access until the end of the period you paid for.
- Refunds are handled by Apple under its own policies.
- Deleting your MuscleMaxer account does not cancel a subscription. Cancel it with Apple first.
5. Your content
You own the workouts, photos, routes, comments and messages you add ("your content"). You give us a licence to store, process and display your content in order to run the App, including showing it to other people according to the sharing settings you choose. The licence ends when you delete the content or your account, except for copies other people already received.
6. Community rules: zero tolerance
We do not tolerate objectionable content or abusive users. You must not post or send anything that:
- is sexually explicit, violent, hateful or discriminatory;
- harasses, bullies, threatens or impersonates anyone;
- is illegal, infringes someone else's rights, or is spam or advertising;
- reveals someone else's private information.
You can report content and block users from inside the App. We review reports within 24 hours. We remove content that breaks these rules and suspend or remove the accounts of people who post it. Uploaded photos may be screened automatically.
7. Deleting your account
You can delete your account at any time in Settings → Delete Account. This permanently removes your account and data as described in the Privacy Policy. We may suspend or end accounts that break these terms.
8. The App itself
We license the App to you for personal, non-commercial use on Apple devices you own or control, as permitted by Apple's Usage Rules. You may not copy, modify, reverse-engineer or resell it. We may change, add or remove features. Maps and routes use data from OpenStreetMap contributors.
9. Disclaimers and liability
The App is provided "as is" without warranties of any kind, to the extent the law allows. We are not liable for indirect or consequential losses, or for injury resulting from exercise you choose to do. Nothing in these terms limits liability that cannot be limited by law, including your statutory rights as a consumer.
10. Apple
These terms are between you and us, not Apple. In addition:
- Apple is not responsible for the App or its content, and has no obligation to provide maintenance or support for it.
- If the App fails to meet any warranty that applies, you may notify Apple, and Apple will refund the purchase price (if any) for the App. Apple has no other warranty obligation for the App, to the extent the law allows.
- Apple is not responsible for any claims about the App, including product liability claims, claims that the App fails to meet legal or regulatory requirements, and consumer protection, privacy or similar claims.
- If someone claims the App infringes their intellectual property, we, not Apple, are responsible for investigating and dealing with that claim.
- You confirm that you are not in a country subject to a U.S. Government embargo or listed as a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties.
- Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.
11. Changes
If we change these terms in a way that matters, we'll ask you to accept the new version in the App before you continue using it.
12. Governing law
These terms are governed by the laws of the Republic of Türkiye, without affecting any mandatory consumer protection rights you have where you live.
