Privacy policy

Last updated 31 October 2026

Clefwork does not collect, store or share any personal data. Everything you enter stays on your iPhone, in the app's own storage. There are no accounts, no servers, no analytics and no tracking.

Clefwork does not collect, store or transmit any personal data: it has no account, no analytics, no advertising and no network features, and your practice history and settings are saved only on your iPhone (in the app's local storage) and are removed when you delete the app or tap "Reset all progress" in Settings.

Deleting the app deletes all of its data. If your iPhone backs up to iCloud, your entries are part of that backup, which Apple protects under its own privacy policy.

If this ever changes, for example if the app starts showing ads, this page will be updated before the new version is released, and the App Store listing will say which data is used.
