Hello Mr Lawson,
I apologize that the messaging around this is not more clear, but I’ll be improving and clarifying it in an upcoming update.
Essentially, the free version is fine for evaluation in schools, but it’s not intended for extended classroom use. Subscriptions from Indie and Teacher accounts are the only way I can afford to keep the site up and running.
The Teacher version is designed for use in classrooms, and is a much better fit. It provides:
- Simple account management
- Improved privacy (no PII is required or collected)
- Heavily discounted account upgrades for all students
The server attempts to detect when it is being used in a classroom for an extended period, and displays the notifications you are seeing. This detection is not perfect, so some students may see more or fewer notifications depending on the account behavior, but creating more accounts is not guaranteed to make the notifications go away.
