Privacy Policy

Effective Date: December 24, 2025

At Logic for Sudoku, we are dedicated to providing a "sanctuary for logic puzzles." Part of that promise is respecting your peace of mind regarding your personal data. We believe in a premium game experience that is free from intrusive tracking. This Privacy Policy outlines how we handle information on our website.

1. Our Commitment to Privacy

We exist to help you escape the noise, not to add to it. We do not require you to create an account to play our games (Sudoku, 24 Game, Calcudoku, Kakuro, and Futoshiki). We do not sell your personal information.

2. Information We Collect

Personal Information: We do not collect personally identifiable information (PII) such as your name, email address, or phone number.

Technical Data: To ensure the website functions correctly and to improve your experience, we may automatically collect minimal technical data, such as your IP address, browser type, and device category.

3. Cookies and Local Storage

Game Progress: We use local storage (a technology similar to cookies) on your device to save your progress, game settings, and achievements (such as your trophies). This data stays on your device and is not sent to our servers.

Analytics: We may use third-party analytics services (like Google Analytics) which use cookies to help us understand aggregate usage patterns (e.g., which puzzles are most popular). These cookies do not identify you personally.

4. Third-Party Advertising

To support the maintenance of this free resource, we may display non-intrusive advertisements. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to your website or other websites.

5. Data Security

We implement reasonable security measures to protect the integrity of the website. Since we do not store personal user data on our servers, the risk of personal data breach is minimal.

6. Children's Privacy

Our website is designed for a general audience. We do not knowingly collect personal information from children under the age of 13.

7. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. The date at the top of this policy indicates when it was last updated.
