Stop sharing your location with others in your Family Sharing group on Mac
By default, all members of your Family Sharing group can locate your devices that have the Find My app turned on in iCloud preferences. To see each other’s devices, family members can use the Find My app on their Mac, iOS, and iPadOS devices. They can also use a web browser to access the Find My app on iCloud.com. Family members can use the Find My app or Messages app to help meet at a specific place, see when another family member is nearby, or make sure a child is where they expect.
If you need privacy, you can stop sharing your device locations with individual family members.
On your Mac, choose Apple menu > System Preferences, then click Family Sharing .
Select Location Sharing in the sidebar, then deselect the checkbox of the person with whom you want to stop sharing your location.
