Terms of Use

Last updated: October 21, 2026

Summary

1. Agreement

These terms apply to the Gym 2.0 iOS app, the web app at gym2.app and the server they use (api.gym2.app), together "Gym 2.0", which is provided by Colin Rüegg, Switzerland ("we"). By creating an account or using Gym 2.0 you agree to these terms and to the Privacy Policy, which explains how your data is processed. If you don't agree, don't use Gym 2.0.

These terms only cover Gym 2.0 as run by us. Copies or modified versions of Gym 2.0 run by others (see section 12) are not provided by us, and these terms and our Privacy Policy don't apply to them.

2. Who can use Gym 2.0

3. Your content

Your content is everything you add to Gym 2.0: workouts, workout schemes, exercises, images, chat messages and photos, group names and images, your profile and your Gym-AI conversations. It stays yours. You give us the permission to store, process and display it as far as needed to run Gym 2.0, e.g. to sync it to your devices and show your messages to the members of a chat. If we verify an exercise you created for all users, we replace its description and images first. The permission ends when you delete the content or your account, as described in the Privacy Policy.

You may only add content you have the right to share, e.g. photos you took yourself.

4. No objectionable content or abusive users

Gym 2.0 has zero tolerance for objectionable content and abusive users. You must not post, send or upload content, or behave in a way, that:

Blocking and reporting: you can block any user, which stops them from sending you friend requests and direct messages. You can report users, groups and messages with a reason in the app: a message with a long press (or right click), a group or a member in the chat info, and a user also while blocking them (Block and Report). You can also report users and content by email to [email protected].

What we do: we review every report within 24 hours. Objectionable content is removed, and users who posted it are warned, suspended or permanently banned, depending on how serious it is. Illegal content may be reported to the authorities. We may also remove content and suspend accounts that break these terms without a report.

Automatic check of images: profile images, group images and chat photos are checked automatically for nudity when you upload them. Images in which nudity is found with enough certainty are rejected, with a message telling you so. Images with possible nudity are reported to us automatically, whether they were rejected or not, and reviewed like the reports of users. The check can make mistakes: if an image of yours was rejected wrongly, contact us at [email protected]. Only a person decides about warnings, suspensions and bans, never the check alone.

5. Using Gym 2.0 fairly

Don't:

6. Health and fitness

Gym 2.0 is a training log and no medical device. Suggested workouts, stats and Gym-AI answers are general information and no medical advice. Talk to a doctor before you start a new training, especially if you have health problems, are pregnant or injured. Stop training if you feel pain, dizziness or shortness of breath. You train at your own risk.

7. Gym-AI

The Gym-AI answers automatically with a language model and can be wrong, incomplete or inappropriate. Check important information yourself and don't rely on it for decisions about your health. Don't use it to create content that section 4 forbids. Answers can take up to two minutes, and the Gym-AI may be unavailable at times.

8. Availability and changes

Gym 2.0 is provided for free, as it is and as available. We try to keep it running and your data safe, but we can't guarantee that it is always available, free of errors or that no data is lost. Old versions of the apps may stop working with the server and have to be updated. We may change or add features, and we may end Gym 2.0, in which case we tell you in advance so you can download your data.

9. Ending your account

You can delete your account at any time in Settings → Account → Delete Account. We may suspend or delete accounts that break these terms, in serious cases without notice, and accounts that are needed to protect other users or Gym 2.0.

10. Liability

As far as the law allows, we are not liable for damages from using Gym 2.0, its content, the Gym-AI or the content of other users, nor for lost data. This does not limit liability for intent or gross negligence, or where the law doesn't allow it to be limited.

11. iOS app from the App Store

For the iOS app, in addition:

12. Source code

The source code of Gym 2.0 is available at github.com/xcolx/Gym-2.0 under the GNU Affero General Public License version 3 with additional terms. Under this license you may copy, modify and run it yourself, including for a service of your own, as long as you follow the license: you must publish your changes under the same license and show the notice "Based on Gym 2.0 by Colin Rüegg - www.colinrueegg.com". The name Gym 2.0 and its logo are not licensed, so a modified version must not be presented as the original. The exact terms are in the LICENSE and NOTICE files of the repository.

The license covers the code, these terms cover your use of the service we run. If they differ, the license applies to the code. Running your own copy doesn't give you any rights to our servers or the data and content of our users.

13. Changes to these terms

We may update these terms when Gym 2.0 changes. The current version is always available at gym2.app/tos, with the date of the last update at the top. If a change matters for you, we tell you in the app or by email. If you keep using Gym 2.0 after that, you accept the new terms.

14. Law and contact

These terms are governed by Swiss law. Mandatory consumer protection laws of the country you live in stay applicable. Questions about these terms: [email protected].
