# Privacy Policy for Sudoku 67 **Last Updated:** August 4, 2026 This Privacy Policy explains how **Sudoku 67** ("we", "us", or "our"), packaged as `com.copperfox.sudoku67`, collects, uses, and protects information when you use our mobile application (the "App"). By using Sudoku 67, you agree to the collection and use of information in accordance with this policy. --- ## 1. Information Collection and Use We respect your privacy. Sudoku 67 **does not require user account registration**, nor do we directly collect or store personally identifiable information (such as your name, email address, physical address, or phone number) on our own servers. However, the App utilizes third-party SDKs and service providers that may collect non-personally identifiable information and device identifiers to provide advertising, process in-app purchases, and enable app functionality. ### A. Information Stored Locally on Your Device To provide a smooth gaming experience, Sudoku 67 stores data locally on your device (using local device storage): * **Game Progress & States:** Current puzzle board layout, notes, timer state, and move history. * **Game Statistics & History:** High scores, games played, completion times, and win rates across difficulty levels. * **App Preferences:** Theme selection, sound/haptic settings, and game options (e.g., auto-check mistakes, highlight duplicates). *This data remains strictly on your device and is not transmitted to our servers.* ### B. Information Collected by Third-Party Services The App incorporates third-party services that collect device-level data and identifiers: #### 1. Google AdMob (Advertising) We use **Google AdMob** to display advertisements (banner, interstitial, and rewarded ads). AdMob may collect and process information such as: * **Online Identifiers:** Android Advertising ID (AAID). * **Device Details:** Device model, operating system version, mobile network information, and IP address. * **Ad Interaction Data:** Views, clicks, impressions, and performance diagnostics. This data is used to serve relevant (personalized or non-personalized) ads, measure ad performance, and prevent fraudulent activity. * For more information on how Google uses data, visit: [Google Privacy & Terms](https://policies.google.com/privacy) and [How Google uses information from sites or apps that use our services](https://policies.google.com/technologies/partner-sites). #### 2. RevenueCat & Google Play Billing (In-App Purchases) We use **RevenueCat** alongside **Google Play Billing** to manage in-app purchases (such as removing advertisements or unlocking premium features): * **Purchase Receipts & Transaction Identifiers:** Anonymous app user ID, purchase tokens, store transaction IDs, product IDs, and subscription status. * **Device Telemetry:** Device IP address, operating system, and country/region settings necessary for billing compliance. *RevenueCat does not store your credit card or financial payment details. All payments are processed securely by Google Play Store.* * For more information, visit: [RevenueCat Privacy Policy](https://www.revenuecat.com/privacy). --- ## 2.
