Effective date: June 20, 2026

Sudoku Challenge is a Sudoku game that can be played offline, but the app now uses Firebase services for analytics and crash reporting.

Information We Collect

Sudoku Challenge does not require an account, does not ask for contact information, and does not request location access.

The app uses Firebase Analytics and Firebase Crashlytics. These services may process technical and usage data such as:

• app launches and general in-app usage events
• app version, device model, OS version, and language
• crash logs, stack traces, and diagnostic information
• coarse identifiers used by Firebase to distinguish app instances

Internet And Third Parties

The app is designed to support offline gameplay, but it can use internet access to send analytics and crash diagnostics to Google Firebase. We do not run our own gameplay backend for puzzle solving or account systems.

Local Game Data

The app may keep local gameplay state on the device in future versions, such as preferences or progress. Local data stays on the device unless the user or Android system backup settings move it.

Children

The app does not knowingly collect information from children.

Changes

This policy may be updated when app features change. The effective date above should be updated with each material change.
