This Privacy Policy explains how ijou.de/sign (Benjamin Maurer) ("we", "us", or "our") handles information in connection with the mobile game cards of ijou (the "App"). The App is available for iPhone and iPad and may also be used on compatible Mac devices.

1. Information We Collect

We do not collect personal data directly from users except for the information needed for leaderboards and achievements.

• Game Center username
• Game Center scores / leaderboard data

Local game data is stored on your device. Highscore data may also be synchronized with Game Center and stored on our server for leaderboard functionality.

2. How We Use Information

We use the limited data described above only to:

• display and maintain leaderboards
• support Game Center achievements
• provide core game functionality related to highscores

3. In-App Purchases

The App uses Apple StoreKit for in-app purchases. All payments are processed through Apple's in-app purchase system. We do not process payment card details ourselves. Purchase history is handled through Apple APIs.

4. Notifications

The App may send push notifications, including a daily gem reminder at 8:00 AM, if you allow notifications on your device. You can disable notifications at any time in your device settings.

5. Analytics, Ads, and Tracking

6. Crash Reporting

Crash reporting may be provided through Apple services on an opt-in basis. We do not use external crash reporting tools.

7. Data Storage

• On-device: local game progress and related game data are stored on your device.
• Server: highscore data is stored on a server under our control and hosted in Germany.

8. Data Retention

Highscore data is generally retained until a new version of the App is released, at which point highscores may be reset. Local device data remains on your device unless you delete the App or remove it yourself.

9. Data Sharing

We do not sell or share your personal information with advertisers, data brokers, or marketing partners. Data is only used as necessary to provide App functionality, including Game Center features and leaderboard support.
