Puzzles and play records

The app stores Sudoku grids, handwritten digits and notes, solving state, play records, settings, and imported-puzzle information on the device. It has no account or CloudKit sync.

Camera, photos, and Vision

When importing from a photo or camera, Vision recognizes handwriting and the grid on the device. Permission is requested for import and can be changed in settings.

Imported images and recognition results are handled on the device; the app has no feature that sends puzzle images to a developer server.

Puzzle-book purchase

Unlimited puzzle-book access is a one-time StoreKit 2 purchase. Apple’s App Store handles payment, purchase state, and restores.

Stored data and support

You can delete saved puzzles from the problem book in the app. There is no control to delete all play records and settings. To remove all local app data, delete the app through device settings.

We use support messages, attachments, and device or app details to reply and investigate the issue. Share only the relevant parts and do not send payment details.
