  • A privacy preserving location sharing system that shows you a map can only work with offline maps. If the maps arent offline, then that means the server delivering the map data knows where you are.

    I dont know of an offline maps based live location app. There are plenty of non google apps that do this in a non private way as a primary or secondary function. Matrix/Element can do it and there are apps on fdroid (ToLoShare for example), that do it. But all of those have to somehow depend on a server that delivers the map “tiles” (chunks of map data near you) to show you a map. So they are all technically capable of tracking you.

    The only really private way to do this is to share the coordinates through a secure channel in an automated way and then whenever you need it you open those coordinates in you offline maps app (CoMaps for example)
