Information We Collect

We collect very little personal information:

  • Information you send us: if you email us, we receive your name, email address and the content of your message.
  • Log files: like most websites, our server automatically records standard data such as your IP address, browser type, internet service provider, date and time of visit, referring/exit pages and number of clicks. This data is not linked to personally identifiable information.
  • Cookies: small files stored in your browser that help the site work and help us understand traffic (see below).

We use the information we collect to:

  • Operate, maintain and improve the website and our cmatrix tutorials
  • Understand how visitors use the site and which guides are most helpful
  • Reply to your questions and feedback
  • Detect and prevent spam, abuse and security issues
  • Show relevant advertising that keeps the site free

We do not sell, rent or trade your personal information to anyone.

Third-Party Advertising and Analytics

Other advertising partners and analytics services (such as Google Analytics) may use cookies, JavaScript or web beacons in their ads and links. They automatically receive your IP address when this occurs.

Please consult the privacy policies of these third parties for more detailed information and opt-out instructions.

Third-Party Links

Our guides link to external sites such as GitHub and Linux distribution package pages. This Privacy Policy does not apply to those websites, and we are not responsible for their privacy practices.
