Accounts, progress and limits
You do not need an account
Every map, callout and setup is readable with no account at all, and the quiz works as a guest. Guests get ten questions a round, and nothing is remembered afterwards.
What an account adds
A free account remembers what you have been quizzed on: anything you miss comes back immediately, and anything you get right waits a day before it is asked again. Free accounts get 25 questions a day and keep mastery for three maps, whichever three you drill first.
Your own setups
"My setups" in your account is for what your stack actually runs. Pick a map and a site, tap rooms on the plan to add placements, and write a line on each one saying why. The free plan keeps one of these; Pro keeps 200 and can share them by link.
What Pro adds
Unlimited questions, rounds of up to 50, mastery on every map, proper spaced-repetition scheduling, the two advanced quiz modes, and up to 200 of your own saved setups with share links. It unlocks no content: the library is free for everyone, with or without an account.
Signing in
There is no password. You enter your email, we send a link, the link signs you in and then stops working. If the email does not arrive within a couple of minutes, check spam — and if it is not there either, tell us, because that is a bug worth knowing about.
Deleting your account
Settings → Delete account. It removes everything immediately and is not reversible. If you have an active subscription the deletion is refused until you cancel it, so that the account cannot disappear while the card is still being charged. Cancel in the billing portal, then delete.
