This Privacy Policy explains how PuzzleNest ("we", "us", "our") handles information when you use our free puzzle-solving tools. We built PuzzleNest to be simple and private by design — most of our solvers run entirely in your browser.
PuzzleNest's solver tools (Hangman, Codeword, Sudoku, Kakuro, Block Blast, and Sliding Puzzle) process everything you enter locally in your browser. The puzzle data you type in — grids, patterns, letters, or numbers — is not transmitted to or stored on our servers.
We may automatically collect limited technical information when you visit our site, such as:
We may use cookies or similar technologies to understand how visitors use our site and to improve performance. You can disable cookies through your browser settings at any time; doing so will not affect your ability to use any of our solver tools.
If you use our Contact Us form, any information you provide (such as your name, email, and message) is used solely to respond to your inquiry and is not sold or shared with third parties.
We may use third-party services (such as analytics or advertising providers) that collect information in accordance with their own privacy policies. We encourage you to review those policies if you'd like more detail on how they handle data.
PuzzleNest is not directed at children under 13, and we do not knowingly collect personal information from children.
Since our solvers process data locally in your browser, there's generally nothing to delete on our end — simply closing or refreshing the page clears any information you entered.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
If you have questions about this Privacy Policy, please reach out via our Contact Us page.
