Introduction
Welcome to NumCase. We are committed to protecting your privacy. This privacy policy describes how we handle information when you install and use the NumCase mobile application on Android devices.
100% Offline & Private by Design
Strict Privacy Guard: NumCase is designed to operate completely offline. Your numerical bases, mathematical calculations, and histories are computed locally on your system. We do not transmit or expose your calculations to any cloud servers.
Information We Collect
Because NumCase does not utilize network cloud synchronization channels for user data, we collect absolutely zero personal identifier records:
- No Personal Information: We do not collect, request, or store names, email addresses, phone numbers, location coordinates, or device telemetry.
- No Transaction Logs: Your conversions (Binary, Octal, Decimal, Hexadecimal, ASCII) and calculator histories are saved exclusively on your local device storage inside a secured sandbox database.
- No Hardware Tracking: We do not track IMEI, MAC addresses, or persistent advertising identifiers.
Device Permissions Used
To deliver modern base-conversion utility, NumCase requests the following Android OS permissions:
- INTERNET: Used solely to support secure local development runtime flows or internal network debugging wrappers. No analytics or tracking data is uploaded over this network interface.
Third-Party Services
We do not integrate malicious third-party trackers, software development kits (SDKs), background advertising packages, or analytics modules that silently scrape your information.
Data Security
Your local conversion and equation history logs are securely maintained in a specialized isolated sandbox environment on your device using the Android Room database engine. Your records cannot be queried by other apps on the device, and you may clear or permanently delete your entire history at any time through the "Clear All" controls inside the History screen.
Children's Privacy
Our application is completely safe for all audiences. We do not knowingly target or collect personal information from children under the age of 13, in strict compliance with COPPA (Children's Online Privacy Protection Act).
Changes to This Policy
We may update our Privacy Policy periodically to align with Google Play Store standards. Any changes will be published here with an updated revision date.
