How to turn off Life360 location sharing for good
Quick answer
To turn off Life360 location sharing, disable it inside the app per circle, then set its location permission to Never in your phone settings to fully stop background access.
Open Life360, tap Settings, and look for Location Sharing, where you can pause it per circle. To stop it completely, go to your phone settings and set Life360's location access to Never, then disable Background App Refresh. Leaving the circle removes you from it altogether. If you still want to know when friends are around, a local proximity app gives you that without anyone seeing your live position.
In one sentence
Parages pings you when you pass near a friend. It tracks nobody.
