Information qa.cafe stores
qa.cafe stores the account details you provide, authentication and security records, your selected learning path, course enrollments, lesson completion, issued certificate snapshots, and messages submitted through the contact form.
Browser practice data
SQL, Python, JavaScript, and TypeScript practice source, runtime data, files, and output stay in temporary browser memory. They are not saved by qa.cafe.
Website measurement
qa.cafe uses privacy-oriented, aggregate website analytics to understand which public learning resources are useful. The measurement configuration does not use advertising profiles or sell personal information.
Public certificates
Certificate verification pages are available to anyone with the cryptographically random verification link. They contain the recipient name, course, revision, issue date, and validity status, but are instructed not to appear in search engines.
Your choices
You may contact qa.cafe to request access, correction, or deletion of applicable personal information. Issued certificate records may be retained independently where necessary to preserve credential integrity.
