Sign in with Google or with Apple. Both can belong to one Mojiya account. To add the second method to an account you are signed in to here, use Add a sign-in method on Account in the study app.
A signed-in account is how a purchase is recognised, and it backs up and syncs your study, in the app and in this browser. The free lessons are open in the browser with no account. It is the same course as on Android and iPhone.
