Privacy

What we collect

• Account details: your email address and, if you give one, your name. These come from creating an account.
• Study data: which questions you answered and whether you were right, your mock exam results, and your flashcard review schedule.
• Optional profile details you enter yourself: exam date, facility, years of experience and daily target.
• Study partner and group data: who you are partnered with, which groups you belong to, nudges you send or receive, and your results in any shared mock exam.
• Standard server logs kept by our hosting provider, including IP address, for security and diagnosing faults.

We do not collect payment details, because no payments are taken. We do not use advertising trackers or third-party analytics profiling.

Why we collect it

• To show your readiness score, progress and review queue, and to keep them consistent across your devices.
• To schedule your flashcards.
• To keep the service working and secure.

What you share with other people

Nothing about you is visible to another user until you have taken an action that shares it. There are four ways that can happen, and this is exactly what each one exposes.

Study partners

If you and another person both accept a partner request, each of you can see the other's readiness score, streak, questions answered, mock exams sat, last mock score and accuracy by domain. Neither of you can see the other's individual answers, profile details or anything else. Removing a partner stops sharing immediately in both directions.

Study groups

A group is a wider disclosure than a one-to-one partnership. Every member of a group — including anyone who joins after you — can see the same aggregates a partner sees, and where you sit on the group leaderboard. Anyone holding the group's invite code can join, so treat the code as the thing that controls access. Leaving a group removes your membership and stops sharing immediately.

Shared mock exams

When you sit a shared mock, your score, your correct-answer count, your per-domain breakdown and how long you took are visible to everyone else invited to that same mock. Your individual answers are not. If you never sit it, the others see only that you have not.

Nudges

Sending a nudge tells the recipient that you sent it and when. We store who nudged whom so the limit of one nudge every three days can be enforced. Nudges are only possible between accepted partners.

Leaving and deletion

Removing a partner or leaving a group stops future sharing at once. Results already recorded in a shared mock remain visible to the other participants of that mock, because it is a shared record of an event rather than something held only about you — ask us if you want one removed. Deleting your account removes your partnerships, group memberships, nudges and shared mock entries along with everything else.

Who processes it

• Neon hosts the database and provides authentication. Your account record and study data sit there.
• Vercel hosts and serves the application, and keeps standard request logs.

These are service providers processing data on our behalf. We do not sell your data and we do not share it with advertisers.

How long we keep it

Your study data is kept while your account exists, because that is what makes it useful. Delete your account and it goes with it.

Your choices

• Reset your practice history at any time from Settings. That clears your progress without closing your account.
• Ask for your account and all associated data to be deleted.
• Ask for a copy of what we hold about you.

Contact us for either of the last two.
