A saved place is a spot the space recognises. What it announces, and to whom, is yours to set.
Pick the spot on a map, name it, give it an icon and choose how close somebody needs to be. The radius matters more than people expect: a very small one causes repeated alerts as the phone drifts in and out, rather than fewer.

Each place has its own arrival and departure alerts. Below them, a per member list lets you switch each person's in and out alerts off for that place alone.

Mark a place quiet and Circl still recognises it, still counts your time there, and tells nobody you arrived. A clinic, a workplace, a house you visit often.
