Privacy Policy
This Privacy Policy explains how the Calculator app ("we", "us", or "our") handles information when you use the app.
What we store
Calculations and in-app settings stay on your device. We don’t run our own servers for this app.
What we collect (Firebase)
To improve stability and understand basic usage, we use Google Firebase for analytics, crash reporting, and performance monitoring.
Firebase may collect limited app and device data, such as:
- an app instance identifier
- device and app info (model, OS version, language, time zone, app version)
- usage events (for example, app opens and feature taps)
- performance metrics (timings)
- crash logs and stack traces
We do not ask for or intentionally collect your name, email, phone number, or precise location.
Permissions
The app does not require special permissions (like camera, microphone, contacts, or location).
Third-party services
We use Firebase via @react-native-firebase/app, @react-native-firebase/analytics,
@react-native-firebase/crashlytics, and @react-native-firebase/perf.
Firebase processes this data on our behalf and may store it on servers outside your country. Learn more: Firebase Privacy & Security and Google Privacy Policy.
Your choices
You can adjust your device settings to limit some analytics (for example, Android “Ads personalization”).
Children’s privacy
The app is not designed to collect personal information from children.
Changes
We may update this policy from time to time. Changes will be posted on this page.
