Sudoku Sanctuary Privacy Policy
Published by ACCORDANT SYSTEMS, INC.
Effective date: September 28, 2026
Sudoku Sanctuary is designed to work without an account. The app does not contain advertising, analytics, tracking, cloud sync, or an in-app purchase system, and it does not collect or transmit personal data from the app.
Information stored on your device
To provide save and resume, non-repeating puzzle selection, Daily Puzzle, statistics, themes, and strategy lessons, Sudoku Sanctuary stores the following information locally on your device:
- saved puzzle progress, entries, notes, elapsed time, mistakes, and help used;
- served-puzzle and Daily Puzzle history;
- local game results and statistics;
- strategy-lesson progress; and
- appearance and gameplay settings.
This information is used only to operate the app on your device. The current app does not send it to the developer or to an analytics, advertising, or cloud service.
Purchases
Sudoku Sanctuary is intended to be offered as a one-time paid download. The app does not process payment information. Store purchases and related account records are handled by Apple under Apple's own terms and privacy practices.
Deleting local information
Individual saved games can be deleted inside the app. Removing the app deletes its active local app data from the device, subject to the device owner's Apple backup and restore settings. Sudoku Sanctuary currently has no account or remote copy from which the developer can recover local progress.
Device permissions and network use
The current app does not request access to contacts, location, camera, microphone, photos, notifications, or advertising identifiers. It does not need an application network connection for ordinary play.
Changes
This policy will be updated before any release that materially changes the app's data handling, account, network, analytics, advertising, payment, or support behavior.
