1. Contact

For help, bug reports, or feedback, email support@kerge.app. Kerge is built by an individual developer in Estonia, so replies are not 24/7 — expect a response within a few business days.

For questions specifically about how Kerge handles your data, see the Privacy Policy or write to privacy@kerge.app.

2. Reporting a bug

To help us reproduce and fix an issue quickly, please include:

• The device model and OS version (e.g. iPhone 14 / iOS 18.2)
• The app version — find it in Settings → About inside Kerge
• What you were doing when the bug happened, and what you expected to see
• A screenshot or screen recording, if it's a visual issue

3. Frequently asked questions

Where is my data stored?

Everything you log — workouts, plans, settings — lives in a local SQLite database on your device. There is no cloud sync and no Kerge account. See the Privacy Policy for the full picture.

How do I back up my data?

Open Settings → Data in the app and use Export to save a copy of your database to your device or a cloud drive. The same screen has an Import option to restore from a previous export.

How do I move my data to a new phone?

Export your database from the old phone (Settings → Data → Export), transfer the file to the new phone (AirDrop, iCloud Drive, Google Drive, email-to-yourself — anything works), install Kerge there, and use Settings → Data → Import.

Why doesn't Kerge sync across my devices?

By design. Kerge has no servers and no accounts — everything stays on your device. Cloud sync is being considered for a future release; in the meantime, manual export/import works as a workaround.

Apple Health isn't showing my workouts

First, make sure permissions are granted: iOS Settings → Privacy & Security → Health → Kerge, and check that both reading and writing are enabled for the data types you care about. Workouts written by Kerge appear in the Health app under Browse → Activity → Workouts.

I can't import a plan from a QR code

Make sure the camera permission is granted: iOS Settings → Privacy & Security → Camera → Kerge (or the Android equivalent). The QR scanner is only active while the import screen is open and the feed is never recorded.

How do I delete all my data?

Uninstalling the app removes the local database and all associated data from your device. There is nothing for us to delete on a server because there is no server.

Is Kerge free?

Yes — Kerge is currently free, with no ads and no in-app purchases.

Which languages are supported?

English, Estonian, Russian, and German. The app picks up your device language automatically; you can override it in Settings → General → Language.
