Privacy respecting location sharing?(find my friends) - Infosec.Pub

My family currently uses life360(iOS and android). But I hate their privacy policy. I’m looking for an alternative. The thing that’s difficult is I can’t find one that’s opt in to each other. Like my parents are split so they dont want to share with each other but the rest of us do. Prefer selfhosted but anything is better that where we are at. Thanks!!

As a graphene user, this and Android auto are there only things I miss about iOS or Google services. I am following this post to see if anything good pops up. I travel a lot for work and I like my wife to know my location.
Locus is the best one i found so far
