Privacy policy

U88 CurtainCount collects, stores, shares, and tracks no personal data. The app works entirely offline and has no accounts, advertising, analytics, tracking tools, servers, or Internet permission.

What stays on your device

Window measurements and calculation results remain in memory during the app session. They are not saved to disk or transmitted. Only your light or dark theme preference, which is not personal data, is stored locally. Android app backup is disabled.

Offline contact draft

The Contact screen does not send or submit anything. Draft text stays only in memory and is discarded when you leave the screen. Do not enter sensitive information.

No third-party collection

The app requests no sensitive permissions, sells or shares no personal data, and does not track users across apps or websites. Clear app storage or uninstall the app to remove the locally stored theme preference. There is no server-held data to access or delete.

Future changes will be reflected here with a new effective date. Developer contact information is available in the Google Play listing; the app does not open external contact or privacy pages.
