Last updated: 25 October 2026. This policy explains what information Sudoku Shrine ("we") uses when you visit this website.

No accounts

You can play every puzzle without signing up. We do not ask for your name, email address or any other personal details.

Information stored in your browser

Your puzzle progress, timer and cookie choices are saved in your own browser using local storage. This information stays on your device and is not sent to us. Clearing your browser data removes it.

Advertising and Google

We may show ads provided by Google AdSense. Third party vendors, including Google, use cookies to serve ads based on your previous visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and other sites on the internet.

You can opt out of personalised advertising by visiting Google Ads Settings, or opt out of third party vendors' cookies at aboutads.info. Learn more in how Google uses information from sites that use its services.

Visitors in the European Economic Area, the UK and Switzerland are asked for consent first. Without consent, only non-personalised ads are requested. You can change your choice at any time in Cookie Settings.

Server logs

Like most websites, our hosting provider may briefly record technical data such as your IP address and browser type to keep the site secure and working.

Children

Sudoku Shrine is a general audience website and does not knowingly collect personal information from children.

Your rights

Depending on where you live, you may have the right to access, correct or delete personal data and to withdraw consent. Because we do not hold personal data ourselves, most choices are made in your browser or in Cookie Settings.
