Who sees my check-ins?
Staff see the cohort, not your individual answer. Your weekly check-in feeds a group-level view (like the share of students finding a week hard), and that is what the wellbeing team looks at. No one is reading a list of names against faces.
When a person does see something
There is one exception, and it is one you control. If you pick I need help on the check-in, or raise a help request, a staff member reads that, because the whole point is that you wanted someone to know. Nothing else from your check-ins turns into something with your name attached.
Small groups are protected too
If your cohort is small, the breakdown stays hidden until the group is big enough that no one could be identified from it. The numbers only appear once they can be genuinely anonymous.
The fuller picture
For the complete breakdown of what staff can and cannot see, including your tasks, notes, and the wellbeing reads you open (none of which are visible to anyone), see What staff see (and what they don't).
The fastest answer is usually one question away.
