PRIVACY POLICY
CLK-01 · last updated November 12, 2026
THE SHORT VERSION
CLK-01 is a chess clock with player profiles, game history and tournaments, made by Lohm Lab.
CLK-01 does not collect anything about you. There is no account, no ads, no analytics and no tracking. What you put into the app stays on your device.
WHAT THE APP KEEPS ON YOUR DEVICE
- Player names you type in
- Profile photos you choose for players (a copy is kept inside the app)
- Game results, tournaments and titles
- Your custom time controls and settings
All of it is saved in the app's own private storage on your device. Lohm Lab cannot see it and never receives it.
WHAT LEAVES YOUR DEVICE
Nothing, unless you send it yourself. The app does not send or receive data over the internet.
- Backup files. Settings → Backup → Export saves a file wherever you choose. It holds every player, photo, game and tournament. Who gets that file is up to you.
- Android device backup. If you have turned on your phone's backup to your Google account, Android may include this app's data in that backup. That copy is handled by Google under your Google account, and you can turn it off in your phone's settings.
PERMISSIONS
- Vibration, to buzz when a clock is pressed and when a game ends. You can turn it off in Settings.
- Photos are picked through your phone's own photo picker, so the app only ever sees the one picture you choose.
DELETING YOUR DATA
You can delete things inside the app at any time. Clearing the app's storage in Android settings, or uninstalling the app, removes everything it saved.
Because nothing is sent to Lohm Lab, there is nothing for us to delete on our side.
CHILDREN
CLK-01 is made for a general audience and is not directed at children under 13. It collects no personal information from anyone, of any age.
CHANGES
If a later version of CLK-01 changes how any of this works, this policy will be updated first and the date on it will change.
