Privacy Policy — Calculator

Android app · Package: com.atulmore.calculator · Last updated: 11 May 2026

This Privacy Policy describes how the Calculator Android application ("the App", "we", "us") handles information when you use it. By installing or using the App, you agree to the practices described below.

1. Summary

Calculator is a fully offline calculator. It does not require an account, does not transmit any data, does not show ads, and does not include any analytics or tracking. All your data stays on your device.

2. What the App does on your device

• Performs basic and scientific calculations (digits, operators, percent, sin/cos/tan with degree/radian toggle, log, ln, square root, factorial, reciprocal, powers, π, e, parentheses).
• Shows a live result preview as you type the expression.
• Keeps a history of past calculations, grouped by date.
• Switches between light and dark themes automatically based on your system setting.
• Vibrates briefly when you tap a button (haptic feedback).

3. Data stored on your device

The App stores one item locally on your device using Android's standard local storage (AsyncStorage):

• Calculation history — a list of past expressions and results, each with a timestamp.
  Storage key: @calculator_history

This data:

• Stays on your device and never leaves it.
• Can be cleared at any time by long-pressing history items and choosing Delete.
• Is fully removed when you uninstall the App.

4. Information we do not collect

The App does not:

• Collect your name, email, phone number, or any identifier.
• Track your location.
• Access your contacts, photos, microphone, or camera.
• Make any network request (you can verify by using the App in airplane mode — every feature continues to work).
• Include any third-party advertising, analytics, crash-reporting, or social-login SDKs.

5. Android permissions

The App declares only two Android permissions in its manifest:

• VIBRATE — used for short haptic feedback on each button tap.
• INTERNET — declared by the React Native framework as a default, but the App's own code does not make any network requests.

The App does not request storage, camera, location, microphone, contacts, notifications, or any other sensitive permission.

6. Third-party services and libraries

The App contains no third-party advertising, analytics, crash-reporting, or social-login SDKs. The only non-UI library bundled is @react-native-async-storage/async-storage, which stores history locally on the device and does not contact any server. Distribution is via Google Play, governed by Google's own privacy policy.

7. Children's privacy

Calculator is suitable for all ages. Because the App collects no personal information, there is nothing for parents or guardians to review, delete, or opt out of.

8. Changes to this policy

If we materially change this Privacy Policy, we will update the "Last updated" date at the top of this page.
