Account
An account is optional. Everything you do is already saved on this device without one. Signing in adds a single thing: your progress follows you to another computer. You can also keep using the backup file either way — nothing about it changes.
Build — · if you report a problem with accounts, quote this.
Sign in
Your progress on this device will be merged with whatever is on your account — nothing is overwritten.
Create account
Your existing progress on this device becomes the starting point — nothing is lost by signing up.
A short phrase you can remember beats a short jumble you cannot. There are no silly symbol rules here — length is what actually matters.
Reset your password
We’ll email you a link. It works once and expires in an hour.
Signed in
Your progress syncs to your account. Sync is safe to run from either computer, in any order — it merges, it never overwrites.
Delete account
Permanently removes your account and everything stored on the server. Your progress on this device is untouched — it just stops syncing. This cannot be undone, so export a backup file first if you want one.
Choose a new password
Almost done — pick something you’ll remember. Length beats symbols.
Accounts aren’t available right now
The account service isn’t responding. This changes nothing about your studying — your progress is saved on this device exactly as always, and the backup file still works. Try again later.
