Free, no account, no ads. Your class list is stored in this browser and never sent anywhere.
This is not a record for the office. It is the switch that tells the rest of the site who is not here, so the picker does not call on an empty chair in front of the whole class.
Tap a name to mark them out, tap again when they arrive late. The class list itself never changes.
Names are held in this browser and nowhere else. Nothing is transmitted, so there is no student data sitting on a server belonging to someone you have never met — which also means there is nothing to request, audit or delete.
The trade-off is honest: if the school wipes profiles or you move rooms, the list goes with it. Copy the list to your clipboard from any tool and paste it back in a moment.
No. It is a quick in-lesson marker so the other tools skip absent children. Keep your official register wherever you keep it.
Not automatically — you keep control. Tap "everyone is here" to clear it.
Only in this browser. Nothing is uploaded.
