Privacy Policy for DiceMaster – Smart Dice Roller Last Updated: June 20, 2026 Rollix Studio ("we," "our," or "us") operates the mobile application DiceMaster – Smart Dice Roller (the "App"). We are highly committed to protecting your privacy and ensuring you have a safe, secure, and transparent user experience. This Privacy Policy explains how we handle information in connection with your use of the App.

1. 100% Offline & Local Processing DiceMaster is designed to run entirely on your mobile device. No Cloud Servers: All dice rolls, mathematical formulas, history logs, settings, and custom presets are generated and stored locally on your device (using Android SharedPreferences). Data Deletion: Since your data is strictly local, uninstalling the App will permanently delete all your local history logs and saved custom presets. We have no way to retrieve or back up this data for you.
2. Zero Personal Data Collection We respect your privacy. We do not collect, store, upload, or share any personal data. We do not ask for your name, email address, phone number, device identifiers (such as IMEI or Android ID), or IP address. We do not integrate any external account sign-ins (e.g., Google Sign-In, Facebook Login).
3. Zero App Permissions (Permission-Free) To guarantee your ultimate privacy, DiceMaster operates without requesting any device permissions. No Network Permissions: The App does not require internet access to function. No Vibrator/Haptic Permission: As of Version 1.1, we have completely rebuilt our canvas physics loops and removed legacy vibration APIs. The App requires zero permissions (the android.permission.VIBRATE permission has been completely removed). No Location, Camera, or Files Access: We do not request access to your location, camera, microphone, contacts, or internal device storage.
4. Third-Party Services & SDKs We prioritize clean software architecture. No Tracking SDKs: We do not use third-party analytics (like Google Analytics, Firebase SDKs, or Flurry) to monitor your behavior. No Ad Networks: The App does not serve advertisements, meaning there are no third-party ad networks tracking your usage patterns or serving targeted ads.
5. Children's Privacy Because we do not collect any personal information, DiceMaster is fully compliant with the Children's Online Privacy Protection Act (COPPA). Our App is safe for users of all ages, including children under the age of 13.
6. Changes to This Privacy Policy We may update our Privacy Policy from time to time. Any changes will be updated directly on this page with a revised "Last Updated" date. We encourage you to review this policy periodically for any changes.
