Privacy, Terms, and Cookies at Pure Sudoku

Privacy Policy

We collect only the information needed to run Pure Sudoku, improve the product, and keep your account secure. This includes your email when you register, gameplay stats, device details for performance, and crash or error reports to diagnose issues. We do not sell your personal data.

Third-party services (like analytics or ads) may set their own cookies. You can opt out of marketing emails at any time, and you can request, export, or delete your data by contacting us at hello@puresudokupuzzle.com.

Pure Sudoku and The Daily Newsfront may infer a coarse city, region, country, or local news market from a request IP address to measure geographic traffic and show relevant local stories. The raw IP address is not stored for this purpose. A random first-party device or browser identifier may be associated with the inferred market so returning visitors receive a consistent edition, including when they are not signed in.

The Pure Sudoku Android app uses Google Play Billing, Google Mobile Ads, Firebase Analytics, and Firebase Cloud Messaging. These services may process app interactions, approximate location derived from an IP address, diagnostics, purchase events, and device or advertising identifiers to provide app features, measure usage, deliver notifications, prevent fraud, and show advertising where permitted. Advertising privacy choices are available in the app when required.

Pure Sudoku Account Deletion

You can permanently delete your Pure Sudoku account in the Android or iOS app. Open Settings, find Account, choose Delete Account, and confirm. This deletes the account and associated personal data from Pure Sudoku's active systems. Some limited records may be retained when required for security, fraud prevention, legal, or financial compliance.

If you cannot access the app, request deletion by emailing hello@puresudokupuzzle.com from the address associated with your account. Include “Pure Sudoku account deletion request” in the subject. We may ask you to verify account ownership before completing the request.

Terms of Service

By using Pure Sudoku, you agree to play fairly, respect other players, and refrain from abusing the platform. Accounts may be limited or suspended for cheating, harassment, or attempts to disrupt gameplay or services.

Pure Sudoku is provided "as is" without warranties. We work to maintain uptime and data integrity, but occasional maintenance or outages may occur. If you have a concern or dispute, please reach out so we can resolve it quickly.

Cookie Policy

We use cookies and similar technologies to keep you signed in, remember preferences (like note mode), and power multiplayer features. Analytics cookies help us understand performance and usage patterns; marketing cookies are used only where applicable and can be limited through your browser settings.

You can manage or block cookies in your browser. Some features—like saving progress, leaderboards, or multiplayer invites—may not work properly without session cookies enabled.
