WatchCalc — Privacy Policy
Last updated: 25 September 2026
WatchCalc is a scientific calculator for Wear OS watches, published by Bunny Pranav. This policy explains what the app does with your information. TL;DR: it doesn’t collect any.
What WatchCalc collects
Nothing. WatchCalc does not collect, store, transmit, or share any personal or sensitive user data.
The app has no account, no sign-in, and no user profile. It contains no analytics, no crash reporting, no advertising, and no third-party tracking SDKs.
Network access
WatchCalc requests no internet permission and cannot make network connections. Every calculation runs entirely on your watch. Nothing you type leaves the device.
What is stored on your watch
So that the calculator behaves sensibly when you come back to it, the app saves the following to private storage on the watch itself:
- the expression currently on screen, and which keypad you were on
- the last result (
Ans) and the memory register (M) - your angle mode (DEG / RAD / GRA) and significant-figure setting
- your last 40 calculations, shown in the History screen
This information never leaves your watch. It is held in the app’s private storage area, is not readable by other apps, and is permanently deleted when you uninstall WatchCalc or clear its storage from your watch’s settings.
You can clear the stored history at any time by uninstalling the app or using Settings → Apps → WatchCalc → Storage → Clear data on your watch.
Permissions
WatchCalc requests a single permission:
-
VIBRATE— to produce the short haptic tick when you press a key. It is not used for anything else and involves no data.
Children’s privacy
WatchCalc is a calculator and is not directed at children under 13. Because it collects no data whatsoever, it collects no data from children either.
Changes to this policy
If this policy changes, the revised version will be posted at this address with an updated date at the top. Since the app collects no data, any change is likely to be a clarification rather than a change in practice.
