Effective date: October 28, 2026

Cool Sudoku uses the following third-party Apple and Google services. Apple services apply to the iOS App. Google services apply to the Android App, and Google Mobile Ads and the User Messaging Platform to both apps.

Apple

• Apple Push Notification service (APNs): delivers optional puzzle and streak notifications to devices that allow them.
• MetricKit: provides performance and diagnostic reports that help us investigate crashes, hangs, and reliability issues.
• App Store In-App Purchase: processes payment for optional purchases and reports transactions so the App can deliver and restore them.
• App Tracking Transparency: iOS may request tracking permission before advertising-related tracking where applicable.

Google

• Firebase Cloud Messaging (Android): delivers optional puzzle and streak notifications to Android devices that allow them.
• Google Play Billing (Android): processes payment for optional purchases and subscriptions and reports them so the App can deliver and restore them.
• Google Play Install Referrer (Android): tells the App on its first launch which store link, if any, led to the install.
• Google Play In-App Review (Android): shows Google Play's rating prompt.
• Google Mobile Ads SDK (AdMob, iOS and Android): loads interstitial and rewarded ads, measures delivery, and confirms eligible rewards. On Android it uses the Android advertising ID.
