Privacy Policy

Last updated: 18 May 2026

This policy applies to CalcMaster — both the Android app (package com.calcmaster.app, published on Google Play) and the website at calcmaster.pooniya.com. Both run entirely on your own device. We do not collect, store, transmit, or share any personal data.

What we store on your device

• Your theme & language preference — saved locally (localStorage on the web, AsyncStorage in the Android app).
• Your favorites & calculation history — saved locally (localStorage on the web, AsyncStorage in the Android app).

All of this stays on your device. It is never sent to a server. You can clear it anytime by clearing browser data (web) or uninstalling / clearing app data (Android).

What we do NOT do

• No analytics or telemetry.
• No advertising or ad networks.
• No third-party trackers, no cookies for tracking.
• No user accounts, sign-in, or sign-up.
• No network requests for your calculations — everything runs on-device.
• No location, contacts, camera, microphone, or any sensitive permissions.

Permissions the Android app uses

Only the minimum required by Android to install and run an app. The app does not request runtime permissions for location, contacts, storage of user files, camera, microphone, or any other sensitive resource.

Children's privacy

CalcMaster does not collect data from anyone, including children. The app is safe for all ages.

Changes to this policy

If anything material changes (for example, if a future version adds analytics or ads), this page will be updated and the "Last updated" date above will change.
