Privacy Policy

TScalc (“the app”) handles your calculations only on this device.

Information we collect

The app does not send or collect any personal information or calculation content to the developer or any third-party server. It uses no advertising, analytics or tracking, and it does not connect to the network.

What is stored on the device

The calculation history (latest 100 entries), the previous answer and the angle unit (DEG / RAD) are stored only on this device so they are available the next time you open the app. You can delete the history at any time with “Clear All” in the history list. Deleting the app removes all of this data.

Clipboard

The app copies a number to the clipboard only when you tap the answer. It never reads the clipboard.
