Terms of Use
Last updated: October 8, 2026
These terms govern your use of the MuscleGains iOS app. By creating an account you agree to them.
What MuscleGains is — and isn't
MuscleGains is a fitness tracking tool for healthy adults. It provides AI-generated estimates (food recognition, nutrition ranges, physique trends) and AI-generated suggestions (workout plans, coaching summaries). All estimates are approximations and all suggestions are general fitness information.
Eligibility
You must be at least 17 years old to use MuscleGains.
Your account
- Keep your login credentials to yourself; you're responsible for activity on your account.
- Log only your own data and upload only photos you have the right to use.
- Pick a display name that isn't offensive or impersonating someone else — it's visible on leaderboards.
Fair play
Discipline points and leaderboards only mean something if they're earned. Don't fake meals or gym photos, abuse scoring, or attempt to manipulate leaderboards or group challenges. We may recalculate points, remove entries, or suspend accounts that game the system.
Premium subscriptions
- Premium costs $14.99/month or $119/year (prices may vary by region and are shown in the App Store before purchase).
- Payment is charged to your Apple ID at confirmation of purchase.
- Subscriptions renew automatically unless cancelled 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 anytime in iPhone Settings → your name → Subscriptions. Cancellation takes effect at the end of the paid period.
- Refunds are handled by Apple under App Store policies.
- If you delete your account, your subscription does not cancel automatically — cancel it in your Apple ID subscriptions as well.
Your content
You own the photos and data you put into MuscleGains. You grant us the limited license needed to store and process them to provide the app's features to you (described in the privacy policy) — nothing more.
Availability and changes
We're a small team improving the app continuously. Features may change, and AI providers or estimates may be updated or replaced. We aim for high availability but don't guarantee uninterrupted service.
Termination
You can stop using MuscleGains and delete your account at any time in Settings → Account → Delete account. We may suspend or terminate accounts that violate these terms.
Limitation of liability
To the maximum extent permitted by law, MuscleGains is provided "as is", and we are not liable for indirect or consequential damages, injuries arising from training or dietary decisions, or inaccuracies in AI-generated estimates. Nothing in these terms limits liability that cannot be limited by law.
