On-device computation
Every calculator in CalcMaster — across the School, University, Work and Health categories — runs as pure code on your device. No formula, value, or result is sent to any server we control.
Network connections
The internet is used only by Google AdMob to load ads (see “Advertising” below).
Permissions the app requests
- Internet / network state — required to load ads.
The app does not request location, contacts, microphone, camera, or storage.
Advertising
CalcMaster shows ads provided by Google AdMob. Google’s advertising SDK collects and processes limited data — for example, your device’s advertising identifier, IP address, and approximate IP-based location — to serve and measure ads. Ads are loaded only when the device has an internet connection.

If you live in a region where consent is required (the EEA, UK, Switzerland, or a US state with applicable privacy law), the app uses Google’s User Messaging Platform (UMP) on first launch so you can choose whether ads are personalized.
Children
This app is not directed at children under 13 and is not classified as a “family” app on Google Play.
