Common Questions

How do I restore my purchases?

Open Settings and tap Restore Purchases. Use the same Apple Account you bought with.

Where is my progress stored?

On your device only. Deleting the app removes it. An iCloud device backup may include it, according to your Apple settings.

How do I cancel a subscription?

Open Settings on your iPhone, tap your name, then Subscriptions, and choose Sudoku Ink.

Does the app need an internet connection?

No. Every puzzle and the Daily Challenge work offline. Only purchases and restore need a connection.
