Terms of use
Muscle Atlas · last updated 29 October 2026
Using the app
Muscle Atlas is free to use and needs an account. You're responsible for the accuracy of what you log and for keeping your login safe.
Not medical advice
Training plans, calorie and protein targets, body-fat estimates and AI food estimates are estimates for general fitness, not medical or dietary advice. Check with a doctor before starting a new training or diet programme, especially if you have a health condition, are pregnant or are injured. Stop any exercise that causes pain.
Your data
Your data is yours. How it is stored is described in the privacy notice: it is stored in your online account, and AI requests go to third-party AI models. You can delete your account and data at any time in Settings.
To keep the beta working, the app sends a small anonymous error report when it breaks (no name, account or typed text; see the privacy notice). You can switch it off in Settings.
No warranty
The app is provided as is. We work to keep it accurate and available but can't guarantee it will be error-free or always online, and we're not liable for losses from using it, to the extent the law allows.
Changes
We may update these terms; the date above shows the latest version.
