KuSoDu is designed to be a calm, focused sudoku app. We do not require an account and we do not run our own user database.

Data Stored On Your Device

The app stores gameplay data locally on your device, including:

• Current puzzle progress
• Notes
• Timer state
• Mistakes
• Hints used
• Local statistics such as wins, losses, best time, and best score

This local gameplay data is used only to run the app and display your progress and stats.

Purchases

KuSoDu does not show ads. Each game includes 3 free hints, and users can optionally unlock unlimited hints for life with a one-time in-app purchase.

In-app purchases are processed by Apple through the App Store. KuSoDu checks App Store purchase entitlements to unlock the feature, but does not run its own account system or payment server.

No Accounts

KuSoDu does not require you to create an account.

No User-Generated Content

KuSoDu does not include user-generated content, public profiles, chats, or social features.

Third-Party Services

The app may use Apple App Store and StoreKit for in-app purchases. These services are governed by Apple's own privacy practices.
