QuickCalc Calculator (com.rongjin.jialan.calqon)
1. Personal Data Handling
QuickCalc Calculator does not collect, store, or share any personal or sensitive user information (such as names, emails, contacts, media, or location).
The app works entirely offline for all calculation and conversion functions. All results, including BMI value calculator, time calculations, and unit conversions, are generated and stored locally on your device.
We integrate Firebase Crashlytics, a crash monitoring service, which may automatically gather anonymous technical details (e.g., device model, operating system version, crash reports) to help identify and resolve stability issues. This data is handled by Google under its Privacy Policy: https://policies.google.com/privacy.
2. History Feature
The History function allows you to revisit your recent calculations. This information is kept exclusively on your device and is never transmitted externally. You can clear it at any time inside the app.
3. Converters and Extra Tools
Features such as unit conversion (length, weight, time, temperature), BMI value calculator, and time difference calculation operate locally without any internet connection. No calculation results or inputs are uploaded or shared.
4. Advertising and Analytics
QuickCalc Calculator does not include ads, tracking tools, or marketing-related SDKs. We also do not use analytics systems that monitor user behavior.
5. Children’s Use
This application can be used by individuals of all age groups. We do not intentionally gather personal details from minors under 13 years old. The app does not contain advertising and does not include tracking mechanisms.
6. Security
Because no personal data is collected, all calculation, conversion, and history results remain within your device. Anonymous diagnostic data may be shared with Firebase Crashlytics strictly for improving technical stability.
7. Updates
This Privacy Policy may be updated from time to time. Any modifications will be reflected on this page with a revised “Last updated” date.
