Privacy and affiliate disclosure

What this site collects

Nothing that identifies you. The site has no accounts, no forms, no comments and no advertising, and it sets no cookies.

  • Visitor statistics. The site uses Cloudflare Web Analytics, which counts page views without cookies and without tracking you across sites. See Cloudflare's privacy policy.
  • Hosting. The site is served by Cloudflare Pages. Like any web server, Cloudflare processes your IP address to deliver the pages and protect them from abuse.
  • Fonts and diagrams. Pages use your device's own fonts, so no font service is contacted. Pages that contain diagrams load the Mermaid drawing library from unpkg.com, a public code CDN, which sees your IP address when it serves the file.

Links to the practice tests go to Udemy and include a DataCertLab referral code. Udemy pays DataCertLab more for a purchase made through these links; the price you pay is the same. Once you leave this site, Udemy's and GitHub's own privacy policies apply.
