Plato Pod

Teachers sign in to make a room: a class, a workshop, a rehearsal. Everyone else needs only the room's code: join a room.

What this server keeps: a teacher's email, name and organisation, the rooms they make, and the name each person joins a room with. Nothing is shared or used for anything else. The records are backed up nightly, and an account is removed when its owner asks through platopod.com.
