Overview
SimpleCalculator ("we", "our", or "the App") is a simple, lightweight calculator application for Android devices developed by Katrex Technologies. This Privacy Policy explains how the App handles user information.
Information We Collect
SimpleCalculator is designed to function completely offline without collecting or transmitting any user data.
We do NOT collect personal information (such as your name, email address, phone number, physical location, or device identifiers), calculation inputs, math history, or usage statistics.
How the App Uses Data
Because SimpleCalculator does not collect any data, there is no storage, processing, profiling, or sharing of user information.
All calculations and optional history records are computed and retained strictly on your physical Android device. No data ever leaves your device.
Permissions
SimpleCalculator requires ZERO sensitive device permissions.
The App does not access your Camera, Contacts, Microphone, Location, External Storage, or Phone State.
Standard non-sensitive system calls, such as haptic vibration feedback on button touch, run locally inside the operating system.
Third-Party Services
SimpleCalculator does not integrate third-party ad networks (such as AdMob), third-party analytics (such as Firebase Analytics or Google Analytics), or any external tracking SDKs.
Data Sharing
We do not sell, trade, rent, or share any user data with third parties. Since no data is collected, no data sharing is possible.
Security
Your calculations and data remain 100% private on your own device. Without network transmission or remote database storage, your usage is inherently protected against online security breaches and network interception.
Children's Privacy
SimpleCalculator is suitable for general audiences. Since we do not collect personal information, there is no user data collection from children or adults. The App fully complies with COPPA and Google Play Families Policies.
Changes to This Privacy Policy
We may update this Privacy Policy from time to time. Any changes will be posted in the updated version with a new effective date on this page.
