# Fitly AI Terms of Service

*This markdown summarizes the terms. The full legal version at https://www.fitly.chat/terms is what actually applies.*

## The short version

- You must be 16 or older to use Fitly AI.
- Fitly AI is **not medical advice**. Consult a doctor before starting any fitness or diet program. You exercise at your own risk.
- You own your data. You grant us a license to use it to run the service, **train our AI models**, and create anonymized datasets.
- We may **share anonymized data** (that can't identify you) with third parties for research and analytics.
- You can **opt out of model training** by emailing privacy@fitly.chat.
- AI-generated content, including readiness or recovery guidance and body-composition estimates, may be inaccurate. Use your own judgment.
- Subscriptions are processed by Apple or Stripe. You can cancel through the provider that manages your subscription.
- We can update these terms with 15 days' notice. Continued use means you accept the changes.

## Account

You're responsible for maintaining the confidentiality of your login credentials and for activity that occurs under your account.

## AI accuracy

AI outputs (meal plans, workouts, nutrition estimates, guidance messages, readiness and recovery guidance, body-composition estimates) are generated by machine-learning models and may contain errors. Use them as a starting point, not as final medical or training advice. Check-in responses, measurement trends and body-fat estimates are wellness tools, not clinical measurements, and do not determine whether it is medically safe for you to exercise.
