Introduction
Welcome to Sort Master. We respect your privacy and are committed to protecting it. This Privacy Policy explains our practices regarding user data, safety, and application operations. Sort Master is built with high standards of data security and user privacy as an offline-first utility tool.
1. Offline-First Policy (No Data Collection)
Sort Master operates 100% offline. All operations, text sorting algorithms, list organization, and processing occur entirely in-memory on your local mobile device.
Privacy Guarantee
We do not collect, store, upload, monitor, or transmit any text lists, strings, logs, or other content you write, paste, or process inside the application. Everything stays securely on your device.
2. Device Permissions
The application only requests the minimum system permissions required to provide features:
- Vibration / Haptics: Required to trigger micro-vibrations for interactive button presses and haptic feedback to enhance the user experience.
- No Internet Permission: The app does not declare or use the internet permission (`android.permission.INTERNET`). It is technically impossible for the application to transmit data over the web.
- No Local Storage Access: The app processes all user actions in temporary runtime memory (RAM), without needing permission to access your private storage files or photos.
3. Third-Party Code & Services
We do not include any advertisement SDKs (like AdMob), user analytics SDKs (like Firebase Analytics), or telemetry packages. Since the app is built using the Flutter Framework, it relies solely on highly vetted, secure open-source packages for state tracking (Provider) and typography (Google Fonts) which do not harvest or access personal information.
4. Children's Privacy
Since the application does not collect any data or communicate with external servers, it is safe for all age ranges, including children under 13. We fully comply with the Child Online Privacy Protection Act (COPPA) and Google Play developer requirements.
5. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. Since the application does not communicate with external systems, we will notify you of any policy updates by releasing a new version of the app containing the updated policy.
6. Terms of Use
By using Sort Master, you agree to this privacy policy. If you do not agree, please do not install or use the app.
