Privacy Policy
Effective Date: September 09, 2026
Hex Calculator mobile application (the "App"). We are committed to protecting your privacy and ensuring you have a positive experience when using our App.
Core Commitment: We do not collect, store, or transmit any personally identifiable information (PII) such as your name, email address, or phone number. All calculation data and user preferences are stored exclusively on your device.
1. Data Collection and Usage
Our App is designed to be fully functional without requiring any user registration or account creation.
- Local Calculation History: The results of your calculations are stored in a local SQLite database on your device. This data is private to the app and is never synchronized with any cloud service or server.
- App Preferences: Your selected theme (Light/Dark), language, and haptic feedback settings are stored locally using SharedPreferences.
2. Third-Party Service Providers
To provide advertisement and notification features, we integrate third-party SDKs. These providers may collect technical data used to identify your device:
- Google AdMob: We use AdMob to serve advertisements. AdMob may collect and use your device advertising ID and location data (if permitted) to personalize ads and provide analytics. Google Privacy Policy
- OneSignal: We use OneSignal for push notifications. OneSignal may collect device tokens, IP addresses, and unique device identifiers to deliver relevant updates. OneSignal Privacy Policy
- System Status API: The App occasionally connects to our server (intlsn.com) to check for maintenance status. This interaction may log standard technical information like IP addresses and user-agent strings in server logs for security and diagnostic purposes.
3. Data Security
The security of your data is important to us. Since your calculation data is stored locally, it is protected by the standard Android application sandbox security. We encourage you to use device-level security (PIN, pattern, or biometric) to protect all data on your device.
4. Children's Privacy
The App is a general-purpose utility for developers and is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you are a parent or guardian and believe your child has provided us with personal information, please contact us.
5. Your Rights
You have full control over the data generated by the App:
- Delete History: You can permanently delete your entire calculation history at any time through the "History" or "Settings" menu within the App.
- Reset App: Clearing the app data in your device settings will remove all local data, including preferences and history.
- Opt-out of Notifications: You can disable push notifications through the App settings or device system settings.
