What this app knows about you.
Your email address, four settings you type, one row for every question you answer, and a name your friends see if you join a league. That is the whole of it. This page names each field because a policy that describes “usage data” in the abstract is a policy nobody can check.

Who runs this
One person, for a handful of students. It is not a company, there is no support desk, and nobody is employed to look at your work. Questions about anything on this page go to furr.christian@gmail.com.

What you type in
Signing in is handled by Clerk, which holds your email address and whichever sign-in method you chose. The app itself never stores your email; it stores an opaque token that Clerk gives it, and every row of your work is keyed on that token.
Settings holds four more things you type: your test date, your target score, the minutes you can give it each day, and — only if you fill them in — a parent’s email address and a first name for you and for them. The names exist so the weekly report can address somebody rather than open with “Dear parent”. Leave them blank and it still reads as a sentence.

What it records while you work
One row per answer: which question, which section, which technique it was drilling, how hard that question was rated, whether you got it right, whether it was timed, how many seconds you spent, and when. Two things are kept up to date from those rows — how well you know each technique, and when a question you have already seen may come back.
None of it is optional, because it is the app. The predicted composite and the plan for today are calculated from the answer history and from nothing else, so an app that did not keep it would have nothing to show you.

If you join a league
A league is a group of friends who have agreed to be ranked against each other. It is the only part of this app where another student sees anything of yours, and it is off until you either start a group or type in a code somebody sent you. There is no directory of groups and no way to find one you were not handed the code for.
Joining stores two things: which group you are in, and a name to show the others. You type that name and it is never your email address, which the app does not hold anyway. It starts as the first name already in Settings only because that is the better guess.
The others in your group then see four numbers about you: how many questions you got right this week, out of how many you answered; the percentage; how many techniques you have mastered; and how many days in a row you have practised. That is the whole list. They do not see a question you answered, a choice you picked, a trap you fell for, your predicted score, your test date, your target, your parent’s address, or anything at all from the days before you joined.
Anyone holding the code can join the group and see those four numbers, so anyone you send it to can pass it on to somebody you have not met. Leaving, which is a button on the league page, takes you off the board immediately: it deletes the membership and the name, and touches nothing else, because your work was never stored inside the group.

What it does not do
There is no advertising, no analytics script, no tracking pixel, and no third party that gets a copy of your work in exchange for a service. Nothing is sold, and nothing is shared for marketing. Clerk sets the cookies that keep you signed in; the app sets none of its own.
- 06
Who else it passes through
Four services, each doing one job. Clerk holds the account and the sign-in. Convex is the database and the server, so everything above sits there. Vercel serves the pages and keeps the ordinary request logs any web host keeps. Resend delivers the weekly report, so the parent’s address and the text of that email pass through it.
There is a fifth, and it is worth being exact about. Pressing the button that writes a fresh question sends a request to OpenRouter carrying a description of the technique and one example question from the bank. It does not carry your name, your email, your score, or a single answer you have given.
- 07
The weekly email
If a parent’s address is saved, one email a week goes to it: how much work happened, which techniques were learned, roughly where the score sits, and what comes next. It holds no individual question and no individual answer. Clearing the address in Settings stops it, and the parent never has an account to close.
- 08
If the student is under 18
This is a study tool for school-age students, and most of the people using it are minors. A parent or guardian may ask for a copy of everything held about their child, or ask for all of it to be deleted, by writing to the address in the first clause. No proof beyond the address already saved on the account is needed if that is the address writing.
- 09
How long it is kept
Until you ask for it to go. Signing out does not delete anything — that is the point of the account, and it is why your mastery survives a new laptop.
Write to the address above and everything keyed to your account is deleted within thirty days: the settings, the answer history, the mastery, any league membership and the name on it, and the sign-in itself. There is no button for this in the app yet, so the email is the way. Leaving a league is the one thing you can already undo yourself.

When this page changes
The date above moves whenever the substance does. If the app ever starts collecting something it does not collect today, that date moves and the clause naming it is rewritten before the collecting starts, not after.
