At Sudoku Game Zone, your privacy is very important to us. We want you to enjoy our puzzles confidently, knowing that your personal information is safe and secure. When you play, the game may save a few pieces of data directly in your browser: your theme preference (light or dark mode) and your best solving times for each difficulty level. This information is stored using localStorage on your own device and never leaves your computer.
We do not collect any personal information such as your name, email, or browsing activity, and we do not share or sell your data to anyone. Your game progress and preferences belong entirely to you. These local settings are saved only to improve your experience, making it easy to track progress and enjoy a seamless game every time. Our site is safe for all ages, and if this policy ever changes, the updated version will be posted here with a new “Last Updated” date. For questions, you can contact us at contact@sudokugamezone.com
