Terms of use

Last updated: 13 November 2026

These terms apply to the Gym Book app and this website. By using Gym Book you agree to them. If you don't, please don't use the app.

Not medical advice

Gym Book gives general training information: plans, suggested weights, recovery estimates and AI-generated suggestions. It is not medical advice and doesn't replace a doctor, physiotherapist or qualified coach. Check with a doctor before starting a new exercise program, especially if you have an injury or health condition. Stop exercising if you feel pain, dizziness or shortness of breath. You train at your own risk.

AI-generated content

Plans, coach replies and suggestions written by AI can be wrong or unsuitable for you. Use your own judgement before following them.

Your account

Gym Book needs a free account. Keep your password safe and make sure the email address is yours. You're responsible for what happens under your account. You can delete it at any time (see how).

Fair use

Don't misuse the service: no attempts to break into it, overload it, access other people's data, or use the AI features to generate content unrelated to training. We may limit, suspend or close accounts that do.

Your data

Your training data is yours. How we handle it is described in the privacy policy.

Availability

Gym Book is provided "as is". We work to keep sync and the AI features running, but can't promise they will always be available or error-free, and features may change over time. The app keeps working offline on your device whether or not the server is reachable. Export your data from the app if you want your own copy.

Liability

To the extent the law allows, we aren't liable for injuries, lost data or other damage arising from using Gym Book. Nothing in these terms limits rights you have under consumer protection law.

Changes

If these terms change, the new version will be posted here with a new "last updated" date.
