"Back to School only" hides the Summer Camp venues and week selector on their Attendance tab, showing just their BTS school and classes.

Doesn't apply to Admin or Manager — they can always get in. Note: this checks the time on the person's own phone, so it's a nudge to keep people out when they shouldn't be working, not a hard lock against someone deliberately changing their clock.

Tick a school to give access to every class there — useful when groups swap partway through a session.
