Welcome to SudokuX ("App", "we", "us", or "our"). We are committed to protecting your privacy. This Privacy Policy explains how information is collected, used, and safeguarded when you use our mobile application SudokuX (Package Name: com.pgdeveloper.sudoku).

1. Information We Collect

SudokuX is designed to minimize data collection. We do not require users to create an account, log in, or provide personally identifiable information (PII) such as your name, email address, phone number, or physical address.

• Local Device Storage: The App stores your gameplay progress, statistics (games played, win streaks, best completion times), and user preferences (such as Dark Mode settings) locally on your device via SharedPreferences. This data remains on your device and is not transmitted to our servers.
• Device & Usage Data (Automated): Through third-party services (such as Google Mobile Ads), non-personal diagnostic data, advertising IDs (e.g., Google Advertising ID), device model, OS version, and network state may be processed to deliver advertisements and analyze ad performance.

2. Third-Party Services & Advertisements

Our App integrates third-party services to deliver advertisements (Banner, Interstitial, and Rewarded Ads). These services may collect and process information used to identify your device in accordance with their respective privacy policies:

• Google Play Services: Google Privacy Policy
• Google AdMob: AdMob & Data Privacy Information

These third-party ad networks may collect anonymized advertising identifiers (Ad ID) to display relevant, personalized, or non-personalized ads based on your device settings.

3. How We Use Information

The non-personal data collected is used solely to:

• Maintain and improve app functionality, game state persistence, and offline play capabilities.
• Serve non-intrusive banner, interstitial, and optional reward-based ads.
• Ensure stability, combat ad fraud, and maintain app security.

4. Children's Privacy (COPPA Compliance)

SudokuX does not knowingly collect personally identifiable information from children under the age of 13. If you are a parent or guardian and believe that your child has provided personal information, please contact us immediately, and we will take prompt steps to remove such information.

5. Data Retention & Security

Because your game saves, statistics, and settings are stored locally on your device, you retain full control over your data. You can erase all app data at any time by uninstalling the App or clearing app data via your device's Android settings.

6. Data Deletion Instructions

Since we do not store any personal user data on external servers, deleting your data is instant and effortless:

• Clear Cache/Data: Go to Settings > Apps > SudokuX > Storage > Clear Data on your device.
• Uninstall: Uninstalling SudokuX completely removes all locally saved game files and settings from your device.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated "Effective Date." We encourage you to review this policy periodically.
