Large Sudoku Privacy

Privacy Policy

Large Sudoku is a static browser site. The playable release does not require accounts, signups, or personal profile data.

Gameplay preferences and progress may be stored locally in the browser using localStorage. That local data stays on the device unless a future feature clearly says otherwise.

Large Sudoku may also store static app files and visited pages in the browser cache so the puzzle can reopen more reliably when the connection is weak. This offline cache stays on the device and is not an account or profile system.

Analytics and advertising should be added only after the playable site is stable, legal pages are live, and this privacy notice is updated to match the actual tools in use.

Advertising and Cookies

The current release does not load advertising scripts. The game board, number pad, print pages, and answer pages are designed to stay free of ad placements.

If Large Sudoku enables Google AdSense later, the policy will be updated before activation to name the provider, explain cookie use, and describe how visitors can manage browser or Google ad settings. Any first ad test should stay limited to a single bottom placement on SEO content pages.
