I understand the privacy concerns.
However, I am allowed to track a kid's phone by using "find my". I am not allowed to track their stuff. Now, I need to make sure they carry a phone instead of just telling them to carry their keys if I want to know their wherabouts. Of course, I could sew one of my airtags to their pants, but wouldn't that be more intrusive?
(Just to give a bit of background. I happen to live in a country where kids usually walk to school and roam about the neighbourhood on their own when they are around seven.)
