The Family space

Register

One family account for both. Registration is done on Euler100, where your child’s Euler ID is issued; the same login then opens everything at STELLA.

One family account, two private spaces. The parent holds the account, approves and pays. The player (your child) gets their own login, created by the parent, to browse the Faculty, see every tutor’s calendar in their own time zone, and ask to book. A school teacher may be given a read-only window on progress. Everything the child does here is visible to the parent.

Log in. Your family space comes back with you. One account works on both platforms: the Euler100 login is the STELLA login. Use your Euler100 email and password.

Registration takes a minute, on euler.swiss: it creates the family account and your child’s profile with its Euler ID. The account belongs to you: you approve, you pay, you see everything. The same login works here.

Progress window

Read-only, and only with the parent’s permission; the parent shares a family code with you. Coming after the pilot

One shared account works on euler.swiss and stella.academy (decision A-08), with tiered verifiable parental consent given on euler.swiss. Passwords and PINs are hashed on the server and never shown again.
