These terms govern your use of FitnessKing, operated by Karun George. By creating an account or using the app, you agree to them. If you do not agree, do not use FitnessKing.
Effective 2026-07-22. Questions: support@fitnessking.app.
1. What FitnessKing is
FitnessKing is a personal fitness and nutrition tracking app available at https://fitnessking.app and as a mobile app. It records body measurements, meals, and workouts, and uses AI coaches to generate calorie and macro targets, weekly training plans, and written guidance based on what you log.
2. AI-generated guidance is not medical advice
FitnessKing provides AI-generated fitness and nutrition guidance for general wellness. It is not medical advice, diagnosis, or treatment. Consult a physician before changing your diet or exercise routine, especially if you have a medical condition.
The targets, plans, and commentary the app produces are generated by an AI model from the data you enter. They can be wrong, incomplete, or unsuitable for you. FitnessKing is not a medical device and performs no diagnosis. Do not use it to manage a medical condition, and do not use it in an emergency — contact a qualified professional or emergency services instead. You are responsible for deciding whether any suggestion is appropriate for you, and for stopping if something hurts.
Do not rely on the app if you are pregnant, recovering from injury or surgery, managing an eating disorder, or living with a cardiovascular, metabolic, or other condition affected by diet and exercise, unless a physician has cleared you to.
3. Eligibility
You must be 18 or older to use FitnessKing. By creating an account you confirm that you are.
4. Your account
You are responsible for keeping your password secure and for everything that happens under your account. Give accurate information when you sign up and keep your profile current — the coaching quality depends directly on it. Tell us at support@fitnessking.app if you believe your account has been accessed by someone else. One account per person; do not share it.
5. Acceptable use
Do not: use the app for anyone other than yourself without their knowledge; attempt to access another user's data; probe, scan, or attack the service or its providers; automate access in a way that degrades the service or evades rate limits; reverse engineer or resell any part of it; or use it for anything illegal.
We may suspend or terminate an account that does any of the above.
6. Credits and purchases
AI coaching runs consume credits from your account balance. We grant credits at no charge, and credits may also be offered for purchase through your platform's in-app purchase system where that is available. Any purchase is processed by Apple or Google under their terms — we never receive or store your payment card details.
Credits are a limited, personal, non-transferable licence to use the coaching features. They have no monetary value outside FitnessKing, cannot be exchanged for cash, and cannot be transferred between accounts. We may change how many credits a coaching run costs, and which credit packs are offered, at any time; changes apply to future runs, not to credits you have already spent.
Refunds for purchased credits are handled by the platform you bought them through, under that platform's refund policy. Unused credits are not refunded when an account is deleted.
If your balance runs out, coaching runs stop until you obtain more credits or connect your own Claude subscription (section 7).
7. Bringing your own Claude subscription
You may optionally connect your own Claude subscription so coaching runs bill to your plan instead of consuming our credits. If you do:
- Your relationship with Anthropic — including their terms, their usage limits, and what you pay them — is entirely between you and them. We are not a party to it and do not control it.
- We store the setup token you provide, encrypted, and use it only to authenticate your own coaching runs. You can disconnect at any time, which deletes it.
- If your subscription becomes invalid or is revoked, coaching runs fail with a clear error rather than silently falling back to our credits.
8. Your data and content
You own what you put into FitnessKing. You grant us only the permission needed to run the service for you: to store your data, display it back to you, and send the relevant parts to our AI provider to generate the guidance you requested. We claim no other rights and will not publish, sell, or share your content. Our handling of personal data is described in the Privacy Policy, which forms part of these terms.
9. Availability and changes
FitnessKing is provided as-is and evolves continuously. We may add, change, or remove features, and we do not guarantee uninterrupted availability — the service depends on third-party infrastructure that can fail. We may impose reasonable limits on usage, including rate limits on coaching runs.
10. Ending it
You may delete your account at any time from Profile, then the Danger zone. Deletion is immediate and irreversible, and removes your data as described in the Privacy Policy. We may suspend or terminate your account if you breach these terms or if we stop offering the service, and will give reasonable notice where we can.
11. Disclaimer of warranties
To the fullest extent permitted by law, FitnessKing is provided as is and as available, without warranties of any kind, whether express or implied, including any implied warranty of merchantability, fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that the AI-generated guidance is accurate, complete, safe, or suitable for you, or that the service will be uninterrupted or error-free.
12. Limitation of liability
To the fullest extent permitted by law, Karun George is not liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or goodwill, arising from your use of FitnessKing. Our total aggregate liability for any claim relating to the service is limited to the greater of the amount you paid for the service in the twelve months before the claim (and may be zero) or INR 1,000.
Nothing here limits liability that cannot be limited by law, including for death or personal injury caused by negligence or for fraud.
13. Indemnity
You agree to indemnify Karun George against claims, losses, and reasonable costs arising from your breach of these terms or your misuse of the service.
14. Governing law
These terms are governed by the laws of India, and the courts of India have jurisdiction over any dispute, without regard to conflict-of-law rules. If you use the app from elsewhere, you do so on your own initiative and are responsible for local compliance.
15. Changes to these terms
We may update these terms. If a change materially affects you, we will update the effective date above and notify you by email or an in-app notice before it takes effect. Continuing to use FitnessKing after that means you accept the change.
16. Everything else
If any provision of these terms is unenforceable, the rest remains in force. Our failure to enforce a provision is not a waiver of it. These terms, together with the Privacy Policy, are the entire agreement between you and Karun George regarding FitnessKing.
