Quality Central is a free learning project. This page explains what it stores about you, who else sees it, and how to have it removed.
What we store
- Account: your email address, and your name if you sign in with GitHub.
- Learning progress: completed lessons, quiz scores, Sandbox results, badges, and your daily challenge streak.
- Things you write: lesson comments and votes, bug reports, feedback, and the mock API endpoints you create.
- Usage limits: how many Mock Interviewer answers you have sent today, so the daily limit can be applied.
What other people can see
- Lesson comments are public, together with the name shown on the comment.
- Mock API endpoints you create can be called by anyone who knows their URL, so do not put personal data in them.
- Everything else is visible only to you.
Services that process your data
- Supabase stores your account and everything listed above.
- Vercel hosts the site and keeps standard request logs.
- Vercel AI Gateway sends your Mock Interviewer answers to an AI model provider to generate feedback. Do not include personal details in answers.
- GitHub shares your name and email with us if you choose to sign in with it.
We do not sell your data, show ads, or use analytics or tracking cookies.
Cookies and local storage
The site uses cookies only to keep you signed in, and your browser's local storage to remember progress and settings such as the colour theme.
Removing your data
You can clear your progress, quiz scores, Sandbox results, and badges at any time with Reset progress on the dashboard. To delete your account and everything linked to it, email akavinda97@gmail.com from the address you signed up with.
