You see the things guardians share with guardians, and the notices a school sends out: trip days, fee dates, the shape of the school week. Enough to stay in step with school life.
You do not get a feed of your child's messages, their private 'me' space, or who they talked to. Those belong to the student. Trust is built into the structure, not promised in a paragraph.
The point is to keep you informed without turning a phone into a microscope over a child's shoulder. A calm signal you can act on, kindly.
