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. No Kerge account is required. Optional Google Sheets sync sends workout history to a spreadsheet in your Google Drive. 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?

Google Sheets sync is a one-way export of workout history, not a full backup or device-to-device sync. Use manual export/import to move your app data to another phone.

Apple Health isn't showing my workouts

First, make sure permissions are granted: iOS Settings → Privacy & Security → Health → Kerge, and check that writing is enabled for Workouts and Active Energy. 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 removes the local app database. If you enabled Google Sheets sync, first disconnect it in Kerge, then delete the spreadsheet in Google Drive and empty its trash. Disconnecting or uninstalling alone does not delete the spreadsheet. Delete any exported backups and Apple Health records separately.

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.
