Information we collect

No account or login is required. Exam progress, settings, and KeyTrain state are stored in your browser's localStorage on your device. We do not operate a user database or sell personal information.

Standard web server logs (IP address, browser type, pages requested) may be recorded by our hosting provider for security and operations. We do not use those logs to build marketing profiles.

Cookies and advertising

We may display Google AdSense ads. Google and its partners may use cookies or similar technologies to serve and measure ads, including personalized advertising where permitted by law. You can learn more in How Google uses data when you use our partners' sites or apps and manage ad personalization at Google Ads Settings.

We do not place ads in pop-ups, emails, or software downloads. Ads are not styled to look like navigation or download buttons. Please report deceptive ad placement to patguettlerpages@gmail.com.

Children

Cert Master is intended for certification candidates and adult learners. We do not knowingly collect personal information from children under 13. Contact us if you believe a child has submitted personal data.
