Ezvor (qeelo.cloud) is a free interview-practice platform. This page explains, in plain language, what data it handles. We don't sell your data or show ads.
Without an account
You can use Ezvor without signing in. Your solved problems, submissions, notes, bookmarks, review queue, settings and AI Advisor chats are then saved only in your browser's local storage on your device. Clearing your browser data, or using Settings → Clear this device, removes them.
With an account
When you sign in (email, Google or GitHub) we store:
- Your email address, and the name and profile picture your provider shares.
- Profile details you choose to add (handle, headline, location, bio, links).
- Your practice activity: code you submit, verdicts, solved problems, notes, bookmarks, reviews and settings, so they sync across devices.
- Your AI Advisor conversations.
- Your career target and roadmap checklist, if you use the Readiness page.
Your profile, solved problems and readiness are visible to others only if you turn on a public profile in Settings. Otherwise they are private to you.
Services that process data for us
- Supabase: account sign-in and the database that stores the data above.
- Vercel: hosts the website and handles requests.
- Google and GitHub: only if you choose to sign in with them.
- AI providers (primarily Google Gemini): the problem, your code and your messages are sent when you use the AI Coach, AI Advisor or other AI features, to generate a reply.
- Code runners (Wandbox, Paiza): code that can't run in your browser (for example C++ and Java) is sent to these free compilers to execute. Python and JavaScript run in your browser.
Cookies and tracking
We use your browser's storage to keep you signed in and to save your progress. We don't use advertising or third-party tracking cookies.
Deleting your data
In Settings you can export everything, delete your cloud data, or delete your account. You can also contact us to delete it for you.
