Who we are
SudoCraft is a free sudoku puzzle generator and player. The entire puzzle creation process (generation, colors, difficulty and image export) runs entirely in your browser — we don't send your puzzles or your choices to any server.
What data we collect
SudoCraft has no user accounts, doesn't ask for personal data, and doesn't store your puzzles in any database. The settings you choose (grid size, colors, difficulty) exist only in your browser's memory while the page is open. Your language choice and cookie-consent choice are stored locally in your browser (localStorage), not on a server.
Cookies and ads
This site may show ads provided by third-party advertising networks, such as Google AdSense. These networks may use cookies and similar identifiers to show ads based on your visits to this and other sites.
You can manage or disable personalized ads in your Google account's ad settings at adssettings.google.com, and read Google's own privacy policy at policies.google.com/privacy.
Your rights
Since we don't collect personal data directly, we have no user database to look up, correct or delete. If you still have questions about third-party cookies or ads, contact us at the email below.
Changes to this policy
We may update this page occasionally to reflect changes to the site or advertising partners. The date at the top of this page shows the last update.
