Sudoku Smash - Privacy Policy
Effective date: October 6, 2026
Sudoku Smash is published by KTC Creative Agency / Studios.
1) Data We Process
- Gameplay progress, settings, and inventory are stored on your device so the game works between sessions.
- When you use Scan Puzzle, the camera captures a photo that is processed on-device for digit recognition. We do not upload camera images or store them after recognition completes.
- In-app purchases are processed by Apple through StoreKit (product identifiers and transaction status).
- We use Google Firebase Analytics to collect aggregated, pseudonymous gameplay analytics such as which modes and difficulty levels are played, level starts and completions, failure reasons (for example timeout or incorrect solve), power-up use, tutorial progress, and purchase funnel events. Firebase uses an app instance identifier (and may use the Identifier for Vendor / IDFV). It does not require an account. We configure Analytics without advertising identifier (IDFA) collection.
- Apple may also provide aggregated App Analytics and crash or diagnostic reports through App Store Connect, which may depend on your iOS Analytics & Improvements settings.
2) How We Use Data
- Provide core game functionality and save your progress.
- Deliver consumable in-app purchases (extra lives and power-ups) after Apple verifies the transaction on your device.
- Understand gameplay funnels, difficulty balance, and where players fail so we can improve the game.
- Review aggregated usage and crash information to improve app stability and quality.
- We do not use the analytics data for cross-app tracking or personalized advertising, and we do not collect the advertising identifier (IDFA).
3) Sharing
- Purchase processing is handled through Apple's StoreKit and App Store infrastructure.
- Firebase Analytics event data is processed by Google on our behalf under Google's Firebase/Google Analytics terms. See Google's privacy documentation for Firebase.
- Aggregated analytics and crash data may also be provided to us by Apple through App Store Connect under Apple's terms and your device privacy settings.
- If you open an external website from the app (for example, studio or font license pages), that site operates under its own privacy policy.
- We do not sell personal data.
4) Retention
- On-device progress remains until you uninstall the app or reset app data.
- Analytics retention follows Google Firebase / Google Analytics retention settings for our project.
- Data retained by Apple through App Store Connect follows Apple's policies.
5) Your Choices
- You can adjust haptics, audio, and music in the app Settings.
- Camera access can be revoked in iOS Settings.
- In-app purchases are optional and can be managed in your Apple ID purchase settings.
- You can control whether Apple shares analytics and crash diagnostics with app developers in iOS Settings under Privacy & Security > Analytics & Improvements.
- The app does not currently offer an in-app analytics opt-out toggle. Uninstalling the app stops further analytics collection from that installation.
