RIG-PRO Scientific Calculator (“the App”) is an Android application that provides an offline scientific, equation, calculus, statistics and programmer calculator. This document describes what data the App processes.
The App performs mathematical calculations locally on your device and shows the results on screen.
To make the App convenient, it saves the following locally on your device only (in the App's private storage): your calculation history, selected theme, angle mode, and last answer/memory values. This information never leaves your device, is not transmitted anywhere, and is removed if you clear the history or uninstall the App.
None. The App has no user accounts, no sign-in, no analytics SDK, no crash reporter, no advertising identifier, and no telemetry. Because we do not collect data, we do not share, sell, rent, or transfer any data to any third party.
The App requests no runtime permissions (no camera, location, microphone, contacts, or storage outside its own sandbox).
The App does not knowingly collect data from any user, including children under 13.
If this ever changes, we will update this document and the “Last updated” date above.
