Privacy policy

U90 InsulaWise 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

Dimensions, openings, coverage, waste, and results remain in memory during the app session. They are not saved or transmitted. Only the light or dark theme preference is stored locally. Android 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. 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. Clear app storage or uninstall to remove the theme preference. There is no server-held data to access or delete.

Future changes will appear here with a new effective date. Developer contact information is available in the Google Play listing.
