Data Deletion

Last updated: 22 September 2026

In short

GymWerk has no user account. Your workout data (plans, exercises, history, records) lives exclusively on your device and is never transmitted to us. The only data on our server is what you deliberately sent through the feedback function. So there are two ways to delete data.

1. Delete data on your device

You do this yourself, immediately and without us:

• Individual entries: plans, exercises and history entries can be deleted in the app (long-press the entry, or open it and choose "Delete").
• Everything at once: uninstall the app – or go to Android Settings → Apps → GymWerk → Storage and tap "Clear data". The app is then empty, as if freshly installed.
• Backups: if you exported a backup file via Settings → Data, that file is wherever you saved it (e.g. Downloads or a cloud drive). Delete it there yourself.

We have no access to this data and therefore can neither view it nor delete it for you.

2. Have your feedback deleted from the server

If you sent a message via "Feedback & suggestions" in the app, you can request its deletion at any time:

1. Email support.mgmedia@gmail.com with the subject "Data deletion GymWerk".
2. Tell us the approximate date of your feedback and, if you provided one, the name. A snippet of the message text helps us find the right entry.
3. We delete the entry completely and confirm by email – within 30 days at the latest, usually much sooner.

No copy is kept. Technical backups held by our processor are overwritten on a rolling basis, after 30 days at the latest.

3. Delete training-partner data

If you turned on "Training partners", your display name, pairings and, per exercise, best set and last set are stored on our server. You delete this yourself in the app: Settings → Training partners → "Delete all partner data". This also removes the pseudonymous identifier and all pairings; nothing remains on the server that could be linked to your device.

If you no longer have access to the device, email support.mgmedia@gmail.com and tell us your display name and, if possible, the display name of a partner – that is how we find the entry.

Which data is affected

On the server (only if you sent feedback): message text, an optional name, app version, platform, language setting, timestamp. Stored with Supabase in Frankfurt, Germany (EU), until you request deletion or we have finished handling your feedback.

On your device: all workout data and settings. Keeping or deleting it is entirely up to you.
