What An Account Is For

Two things. It keeps what you have watched and what you thought of it across your devices instead of only in this browser, and it lets the site work out how far along you are so it stops covering up things you have already seen.

What It Stores

Your email address, what you have ticked off, and your grades. That is the whole list. No password, no name, no date of birth, no phone number. It is not shared, it is not sold, and there is no analytics company behind this that gets a copy. You can delete the lot from your account page and it is gone.

You do not need one. Everything on this site is readable without it, and progress saves in this browser on its own.
