Availability
This feature starts off. EDUBase activates it for named pilot schools or all schools in CRM Dashboard → Feature Rollout. Turning this rollout switch off prevents new freezes; it never restores a school already frozen.
Freeze school access
Only the school owner can open Android Owner App → avatar/account menu → Security → Kill switch. Set and confirm the phone-and-account app security PIN on first use, then enter the PIN, type FREEZE and optionally explain the reason. Freezing signs out staff and administrators across EMS and staff apps, and holds school messages until EDUBase restores access. A message already handed to a sending device cannot be recalled. Parents can continue reading their app. The owner remains signed in and sees School access frozen.
Restore access
Contact EDUBase to review and restore access. The owner cannot undo a freeze. EDUBase records a required review note when re-enabling access. Staff must sign in again after restoration; queued school messages resume.
