Privacy
You are a student, not an audience. Nothing here is sold, and nothing you do here is shown to your school.
Effective September 8, 2026
What we collect
Your email address, and what you do in the app: which questions you were served, what you answered, whether it was right, roughly how long you took, and anything you flag. That is the whole of it — we do not ask for your name, your school ID, your grades, or anything about your health.
Payment details go to Stripe and never touch our servers. We keep whether you have paid for the block and what state that is in; we do not have your card.
What we do with it
Serve you your block’s sets and show you your own progress. What you answered is what makes your Review page work, and it is the record future sets can be shaped from, which is why we keep it.
We also read it in aggregate to tell whether the system works — how often sets are finished, how often a question gets flagged, how much a night costs to produce.
What we never do
We do not sell your data, and we do not run ads. We do not show your performance to your school, your course directors or your faculty — not by name and not in a form that could be traced back to you. If we ever report anything to a school, it will be counts across a whole cohort, and we will say so here first.
Where your answers go, and where they do not
Your answers live in our database, and nothing about you reaches any model. The questions are written days ahead from your course materials, not from anything about you, and the sets you see are the same for everyone in your block.
Who else touches it
We run on other people’s infrastructure, and they are named rather than implied: Supabase (the database and your sign-in), Vercel (the website), Modal (the overnight jobs), Anthropic (the model that writes the questions), Stripe (payments), and PostHog (product analytics). Each of them sees only what its job needs.
Cookies
One cookie keeps you signed in. Analytics uses its own. There is no advertising tracker on this site, and there will not be one.
Your data is yours
Ask and we will send you everything we hold about you. Ask and we will delete it — the account, the answers, all of it — and it is not recoverable afterwards, which is what deletion should mean.
Asking
Write to the address your invitation came from. A person reads it.
