Privacy Policy

Effective September 2026

StairWise works privately and offline. It does not collect, transmit, sell, or share personal data or calculator entries. It has no accounts, advertising, analytics, tracking, cookies, network features, sensitive permissions, or third-party sharing.

Information on your device

Measurements and results are used only while you use the calculator and are not saved. Only your light or dark theme preference is stored locally. Clear the app’s storage or uninstall it to remove that preference.

Offline contact preview

The Contact screen is only a local preview. Text entered there is neither sent nor stored.

Sharing and deletion

No data is shared and StairWise holds no data on a server. Therefore there is no server-held personal data to retrieve or delete.

Children’s privacy

StairWise is a general-purpose planning tool and is not designed to request personal information from anyone, including children. Because it collects no personal data, it does not knowingly retain children’s personal information. A responsible adult and qualified professional should supervise real construction planning.

Changes and contact

If data practices change, this policy will be updated before the feature is released. The app’s Contact screen does not send messages; a public support channel may be added to the store listing before release.
