Terms of use
Plain-language terms · updated October 20, 2026
1. Who can use Gainloop
You must be at least 13, and at least 18 to buy a subscription. During the beta, an invite code is needed to sign up.
2. Not medical advice
Gainloop gives general fitness and nutrition information from your own logs. It is not a doctor, dietitian or medical device and does not diagnose or treat anything. Talk to a professional before big changes to diet or training, and stop and get help if something hurts or feels wrong.
3. AI can be wrong
Calorie estimates from photos, workout suggestions and coach answers are estimates. Check anything that matters, especially allergies, medical diets and heavy lifts.
4. Your account
Keep your password private. You're responsible for what happens in your account. You can export or delete your data and your account any time in Settings.
5. Gainloop Pro
Pro unlocks the AI features. Plans are $9.99/month or $49.99/year; the yearly plan starts with a 3-day free trial. Subscriptions renew automatically until you cancel, and you can cancel any time before renewal. Founding beta members get Pro free for the period stated at sign-up.
6. Fair use
Daily AI limits keep the service fast and affordable for everyone. Don't misuse the service, scrape it, or try to access other people's data.
7. Changes
We may update features, prices or these terms. If a change matters to you, we'll tell you in the app or by email before it applies.
8. Contact
