InferQuest

Privacy Policy

Last updated August 21, 2026

InferQuest is a free, non-commercial learning platform. The short version: we store your account basics and your own learning progress, we use them only to run the site, and we don’t sell, share for advertising, or otherwise monetize anything about you.

What we collect

  • Account information. When you sign in (with Google or email), our authentication provider Clerk gives us your name, email address, and profile picture. If you use Google sign-in, that’s all we receive — we never see your password or anything else in your Google account.
  • Learning progress. Which tasks you’ve completed, XP earned, quiz and knowledge-check answers, and your spaced-repetition review schedule.
  • Verification submissions. When you use a verifier, we store the evidence needed to mark the milestone passed: for endpoint probes, the URL and model name you submitted and the probe results — never your API keys, which are used for the probe and discarded; for GitHub PR checks, the public PR URL; for harness submissions, the grading report (which includes your GPU model name).

That’s it. There are no analytics trackers, no advertising pixels, and no cookies beyond the session cookies Clerk needs to keep you signed in.

How we use it

Solely to operate the site: tracking your progress, scheduling your reviews, computing XP and achievements, and verifying milestones. Nothing is used for advertising, profiling, or training AI models, and nothing is ever sold.

Who processes it

  • Clerk — authentication and session management.
  • Vercel — application hosting and the Postgres database that stores your progress.
  • GitHub — when you submit a pull request for verification, we query GitHub’s public API about that PR.

These are processors acting on our behalf; no other third parties receive your data.

Deleting your data

You can delete your account from the account menu (top right), which removes your authentication data with Clerk. To have your progress rows wiped from our database as well — or for any other privacy request — open an issue at github.com/jneums/inferquest and we’ll take care of it promptly.

Children

InferQuest is not directed at children under 13, and we don’t knowingly collect data from them.

Changes

If this policy changes materially, we’ll update this page and the date above. The history is public in the site’s source repository.
