Privacy Policy

This privacy policy explains how Nudge Sokoban ("the game") handles information.

1. Information we collect

The game does not require an account. It does not collect information that identifies you, such as your name, phone number, email address, location, or contacts. To fix crashes and improve level difficulty, we collect anonymous crash reports and in-game events through Google Firebase (see section 3).

2. Local save data

Your progress, stars, and settings are stored only on your device so you can continue playing later. We do not upload this data to a server. Uninstalling the game removes local save data according to your device settings.

3. Network and third parties

The game does not use advertising SDKs, does not collect an Advertising ID, and is not used for advertising or cross-app tracking.

The game uses two Google Firebase services:

• Firebase Crashlytics — when the game crashes or hits an error, it reports the error stack, device model, OS version, and the level you were on, so we can find and fix the problem.
• Google Analytics for Firebase — reports anonymous in-game events such as starting and leaving a level, using a hint, restarting, detecting a deadlock, and the steps of the in-app purchase flow. We use this to tell which levels are too hard and which features go unused.

These services use an anonymous app instance identifier generated by Firebase. It does not identify you personally and is not shared with other apps. The data above contains no name, email address, location, or contacts.

Google's handling of this data is additionally governed by the Google Privacy Policy: https://policies.google.com/privacy

4. Children

The game does not knowingly collect personal information from children or anyone else.

5. Permissions

The game does not request sensitive permissions such as camera, microphone, location, or contacts. It uses network access to send the crash and analytics data described above. Vibration is optional and can be disabled in Settings.

6. Changes

If the game later adds new online features, this policy will be updated and the change will be shown in the game.

7. Contact

For questions about this policy, contact the developer at greg.hsia@gmail.com.
