Your account
An account is optional; everything on this site works without one. It carries your revision between devices: reading, checklist ratings, flashcard boxes and question scores.
Sign in with a Google account and this device’s progress can follow you to another one; revision done anywhere is merged, never overwritten. What an account stores, and how to delete it, is set out on the privacy page.

Set once, carried to every device you sign in on.

Your record
Download your account data, including your email address, synced progress and recent device sign-ins. No password or token is in it, but treat the file as personal data.
Leaving
Signing out puts this account’s progress aside on this device, so the next person to use it starts afresh, and brings it back when you sign in here again. Signing out everywhere signs out every device holding this account the next time it talks to the server. Deleting the account erases the account and everything synced with it, immediately; this library’s copy on this device is removed too.
