I wouldn’t even share my location with my SO of 10+ years. Why? They don’t need it, and there’s tons of potential negative things with that (phone manufacturer sells it, gov’t takes it w/ backdoor deals, breach reveals it, etc).

I don’t want my SO’s location information, and they shouldn’t want mine. If I’m doing some high risk activity, like doing a long hike alone, sure, but it’s going off immediately after.
