Privacy Policy

We keep this policy simple and readable. Our goal is to make fun puzzle games, not collect unnecessary personal data.

What We Collect

  • Game progress in your browser: We save puzzle state, timer, mistakes, and hints using local storage so you can continue where you left off.
  • Emails you send us: If you contact us, we receive your email address and message content.
  • Basic server logs: Like most websites, our hosting provider may store technical logs (for security and reliability).
  • Analytics and advertising data: Google Analytics and Google AdSense may process browser and device details, pages viewed, interactions, approximate location derived from an IP address, and cookies or similar identifiers, subject to consent and age-related settings.

How We Use Information

  • To run the games and remember your in-progress puzzles.
  • To respond when you email us for support or feedback.
  • To fix bugs and improve game quality.
  • To understand how the site is used and improve its content.
  • To serve, limit, and measure advertising.

Children's Privacy

Sudoku for Kids is designed for children and families. We do not require account signup to play. If you believe a child has shared personal information with us by email, contact us and we will remove it.

Google Analytics and Google AdSense

We use Google Analytics to understand visits and Google AdSense to provide and measure advertising. Google may process information from your browser or device for these services. The data available to Google and whether ads can be personalized depend on your location, consent choices, and applicable age protections.

Cookies and Local Storage

We use local storage to keep game progress on your device. You can clear this at any time by clearing your browser site data.

Where required, Google's consent message asks for your choices before optional analytics or advertising storage is used. You can change those choices later through the Privacy and cookie settings link shown on the site.

Your Choices

  • You can stop using the site at any time.
  • You can clear browser storage to remove saved puzzle progress.
  • You can email us to ask privacy questions.
  • You can accept, reject, or manage optional Google cookies in the consent message.
