Information you provide
Printable Sudoku does not require account registration, payment details, or a profile. The puzzle settings you choose—such as difficulty, page layout, and answer-key preference—are used in your browser to prepare the requested printable sheet.
If you voluntarily submit feedback through the linked public issue tracker, the information you post is handled by that platform and may be visible publicly. Do not include personal, confidential, or sensitive information in a public report.
Automatically collected information
Like most websites, our hosting and service providers may receive technical information such as your Internet Protocol (IP) address, browser and device type, operating system, referring page, pages viewed, approximate region, and timestamps. This information helps deliver the site, prevent abuse, diagnose errors, and understand general usage.
Google Analytics
We use Google Analytics to understand how visitors find and use the site—for example, which pages are visited and whether the print feature is used. Google Analytics may collect device, browser, interaction, and approximate location information and may use cookies or similar identifiers. We use these reports to improve navigation, content, and printing reliability.
Google AdSense and advertising cookies
We use Google AdSense to display or prepare the site to display advertising. Google and its partners may use cookies, web beacons, IP addresses, or other identifiers to serve, measure, personalize, and limit ads. Third-party vendors, including Google, may use cookies based on a user’s prior visits to this and other websites.
You can control personalized advertising through Google Ads Settings. You can also learn how Google uses information from sites or apps that use its services. Your browser may let you block or delete cookies, although doing so can affect some website functions.
Consent in applicable regions
Where required by law, visitors may be shown a consent message provided through Google’s consent-management tools before certain advertising or measurement technologies are used. The choices displayed in that message control applicable personalized advertising and data processing. You can revisit available privacy choices through the message or your browser settings when supported.
Legal bases and purposes
Depending on where you live, information may be processed with your consent, to provide the service you request, or for legitimate interests such as security, basic measurement, site improvement, and fraud prevention. Advertising partners may have their own legal bases and privacy notices.
Data sharing and retention
Information may be processed by hosting, analytics, security, and advertising providers that help operate the website. We do not sell a user account database because the site does not maintain user accounts. Providers retain information according to their own settings and policies; aggregated reporting may be kept to compare site performance over time.
Children’s privacy
This is a general-audience puzzle website. We do not knowingly request personal information from children. Parents, guardians, and educators should supervise a child’s internet use and avoid posting a child’s personal information through public feedback channels.
Your choices
- Use browser controls to block or delete cookies.
- Adjust personalized-ad settings through Google Ads Settings.
- Use any consent controls presented on the site in your region.
- Use privacy or content-blocking features provided by your browser, subject to their limitations.
External links
Pages may link to third-party sites. Their privacy practices are governed by their own policies, and Printable Sudoku is not responsible for their content or handling of information.
Policy changes
We may update this policy when the website, service providers, or legal requirements change. The latest version will remain on this page with a revised date.
