Calculatrice has zero network features. The mobile app does not declare the `android.permission.INTERNET` flag in its AndroidManifest.xml. This means that the operating system physically restricts the application from transmitting or receiving any data over the internet, rendering remote data exfiltration attacks mathematically impossible.
To verify that you are running an untampered build of Calculatrice, always cross-reference the SHA-256 checksum of your downloaded installation packages.
The app utilizes standard OS sandboxing rules. Any data cached locally (such as variables, settings, or calculations history) is stored inside the app's isolated local storage partition, which cannot be accessed by other applications on the same device without root access.
