This is a carrier in the USA (T-Mobile).

I did a quick search for the other 2 carriers using the term "[Carrier Name] Family Tracking" and Verizon and AT&T also seems to have it.

And according to https://www.t-mobile.com/support/plans-features/t-mobile-familywhere-app, it says:

FamilyWhere uses geolocation data from the T-Mobile network and is not affected by changes to device location settings.

So it appears that its using cell tower triangulation. Turning on Airplane Mode should stop it (assuming there isn't a separate tracking app on your phone)

Oh Wow, What a wonderful tool for abusive spouses and abusive parents. And telecom companies are making money off of it. ๐Ÿ™ƒ

TLDR: Its a good idea to get your own separate cellular plan.

The sort of thing that'd be really fucking useful, anywhere in the last twenty years - if it was built by privacy nerds. If I'm out with people at a mall or whatever, we should be able to exchange GPS coordinates once per second, using approximately zero percent of any modern server.

But it should be extremely opt-in. Like not even an option to turn on and leave on. And if any fucking brand ever sees that data, the person responsible can track my phone's trajectory through their front window.

Signal can at least share location if not live.

Try Paralino! It's a family location sharing app but is end-to-end encrypted :)
