Studying needs no account, and everything on this page works without one. An account exists to carry your place between this browser and your phone, and to give you somewhere to take it away from.
What this browser knows about you, which is either an email address or nothing at all.
Apple, Google and email have equal weight. Email sends both a six-digit code and a link; none needs a password here.
Nothing here stops working if you never add one. An account only carries your place to another device.
A password is a thing to forget and a thing to have stolen, and an account here holds a log of answers rather than a password of its own. Apple, Google or a one-use email proof is enough, and the same three choices are on the phone.
Your account already exists — it has existed since your first visit, without a name on it. Adding an email puts a name on that account and keeps the same one underneath, which is what makes a purchase, a run of days and a year of answers follow the person rather than the login.
The same four facts every screen in this product quotes about your work — and the four that would follow you to a new browser or a new phone.
This browser is the one device we can honestly speak for, so it is the one this section describes.
Nothing. Everything in this browser has reached your account.
We are not told which machines have your account open, so a table of them would be invented. What we can tell you is what this browser is still holding, and that is what is above.
Signing out changes who this browser belongs to. Deleting removes the work itself, and nothing brings it back.
Deleting takes your answers, your run of days, your predicted score and your plan out of this browser. There is no account holding a second copy.
