I want to address the person who tagged this “what if they’re missing??”
that’s it, that’s the answer.
what this does is allow you to set up a list of people who are able to request your location. when they do so, you have five minutes to either refuse or grant the request. if you don’t respond within five minutes, the request is automatically accepted, in case you’re hurt or otherwise unable to get to your phone. your trusted contacts can also see how recently you used your device.
in other words: if someone genuinely wants to know if you’re okay, they can check the app and see that you’ve used your phone five minutes ago, and that can be the end of it. if they want to be doubly sure, or it says you haven’t used your phone recently, they can request your location. if you want them to know where you are, or you can’t answer, they’ll have your exact location within five minutes. if you don’t want them to know where you are, you click deny, and they still see that you got the request and responded to it, meaning, again, they know you’re okay. this is safety with accountability: you can’t track someone’s location without their consent unless they fail to respond to the notification, and you can’t do it without them knowing about it.
if you want to track a friend or loved one for genuine safety reasons, set this up. it gives you all the access you need if your concern is actually for the other person’s well-being, rather than a desire for control. (it’s not out for iOS yet, but Google says that’s coming soon).
(also: don’t be the jackass that makes a rule that someone has to accept all your location requests because that makes you just as bad as the people who install tracking shit covertly.)
