SudokuPuzzle.pro (“we”, “the site”) is a free browser-based Sudoku game. This page explains what information is stored on your device, how advertising works, and the choices you have.
What we collect
We do not create accounts, and we do not ask for your name, email address, or other personal contact details to play. Puzzle progress stays on your device.
The site uses your browser’s local storage to remember:
- Your current free-play and Daily Challenge puzzles (so you can resume later)
- Points and streak
- Dark mode preference
That data never leaves your browser for those features. Clearing site data in your browser settings deletes it.
Advertising (Google AdSense)
We use Google AdSense to display ads and support the site. Google and its advertising partners may use cookies and similar technologies to serve ads, measure how ads perform, and (where allowed) personalize ads based on your activity on this site and other sites.
Third-party vendors, including Google, use cookies to serve ads based on a user’s prior visits to this website or other websites. Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
You can opt out of personalized advertising:

Cookies and similar technologies
Aside from local storage used for gameplay, advertising partners may set cookies when ads load. We do not use those cookies to identify you as a named individual. Cookie duration and use are controlled by those vendors.
Visitors in the European Economic Area, UK, and similar regions may see a consent message before personalized ads are shown, as required by applicable law.
Children
SudokuPuzzle.pro is a general-audience puzzle site. We do not knowingly collect personal information from children. If you believe a child has provided personal information through this site, contact us using the method below and we will delete it if we hold it.
Changes
We may update this policy as the site or advertising setup changes. The effective date at the top of this page will be revised when we do.
