Privacy Policy
FX-82MS Calculator
This Privacy Policy describes how Hemali Savaliya handles information in connection with the web application FX-82MS Scientific Calculator (available at savaliya-hemali.github.io/Scientific-Calculator-FX82). By using the App, you agree to the practices described in this policy.
1. Data Stored on Your Device
FX-82MS Calculator follows a privacy-first, local-only model. Any data created when you use the App remains entirely in your browser's local storage on your device:
- •Your app preferences and settings
- •Any session data required for the app to function, stored only in your browser
- •No data is ever transmitted to any external server or cloud service
2. Data We Do Not Collect
Just as important is what never happens:
- •No analytics, crash reporting, usage tracking, or advertising SDKs of any kind
- •Nothing is ever uploaded — the app has no servers, backend, or cloud infrastructure
- •No account, name, email, or phone number is required or collected
- •No location or device telemetry data is collected
3. App Permissions
The App requests only the browser permissions it needs to function:
- •Keyboard & Focus Events: Required to capture calculator key shortcuts and physical keyboard input for calculations.
- •Local Storage Buffer: Allows saving persistent memory variables (M+, STO, RCL) across browser sessions.
- •Offline Execution: Runs 100% inside your browser — works without active internet connectivity.
4. Third-Party Services
The App is fully self-contained. It does not integrate any third-party analytics, crash-reporting, tracking, or advertising SDKs. All code runs entirely on your device inside your browser and transmits nothing.
5. Security
The app operates entirely offline within your browser, so your data is never exposed to a network. No method of electronic storage is 100% secure, and we cannot guarantee absolute security. You are responsible for keeping your device and any credentials you set safe.
