Privacy Policy
This policy explains how Sudoku School handles information related to website use, analytics, advertising, cookies, and contact requests.
What this privacy policy covers
Sudoku School is primarily a static Sudoku website, which means most visitors can use the service without creating an account or submitting personal data. Even so, some information may still be processed when you browse the site, use site features, interact with advertising, or contact us directly.
This page explains what information may be involved, why it may be processed, where third-party services fit in, and what choices visitors still have when using the site.
Information we may collect
Technical and usage data
Like most websites, Sudoku School may receive basic technical information such as browser type, device type, approximate location derived from IP address, referrer details, and standard request-level data needed to deliver pages and keep the site working reliably.
Contact form submissions
If you contact us through the site form or by email, we may receive the name, email address, topic, and message details you choose to send.
Cookies and preference signals
Cookies or similar browser technologies may be used to remember preferences, improve site consistency, and help advertising-related systems understand page context where applicable.
Game and interaction context
Sudoku School may also store limited browser-side data related to puzzle state, preferences, or interface behavior so the game remains stable and usable between visits.
How information is used
- To keep the website functioning, rendering correctly, and loading game resources reliably.
- To improve usability, content quality, and site stability over time.
- To respond to contact requests, bug reports, and partnership inquiries.
- To support advertising services and related policy/compliance requirements where ads are shown.
- To maintain reasonable operational and security records when needed.
Sudoku School is not positioned as a user-account platform or a data-heavy SaaS product. Most information handling is operational, communication-related, or tied to basic browser functionality.
Third-party services and data sharing
Sudoku School may use third-party services such as Google AdSense for advertising and Web3Forms for contact form delivery. These providers may process technical data, browser identifiers, or submitted message details according to their own policies and operational requirements.
At the time of writing, Sudoku School does not require user accounts to play core puzzles. If separate analytics, newsletter, or measurement tools are added later, this policy should be updated to describe those changes more specifically.
We may also share limited information when required by law, to enforce site policies, to protect the integrity of the service, or to address operational and security issues.
Retention, security, and your choices
We aim to keep personally submitted information only as long as reasonably necessary to respond to requests, maintain records, or meet legal and operational obligations. No website can promise absolute security, but we take sensible steps to reduce avoidable exposure.
Browser-saved puzzle state, preferences, or other local storage can usually be cleared through your browser’s site-data controls. You can also manage cookies through your browser settings and limit form submissions to the minimum information needed.
