The money is not delegated
The wallet, payouts, financial settings and managing other assistants are all closed to you. That is enforced in the system, not agreed between you and the teacher.
An assistant acts for exactly one teacher: their groups, attendance, grades, materials and collaborations. The money is closed, and every action is recorded under your name on their behalf — never under theirs.



The wallet, payouts, financial settings and managing other assistants are all closed to you. That is enforced in the system, not agreed between you and the teacher.
You cannot assist two teachers at once. That is enforced by the database itself, not by a condition in the code.
Everything you do is recorded as "you, on behalf of them". That is not surveillance — it is what protects you: what you did is attributed to you, and what you did not do cannot be.
The invitation arrives at your own email, and you set your own password — the teacher never sees it and never sets it.
