This is a huge no from me. My SO doesn't need my location, and sharing it has a lot of potential downsides, like:
- phone manufacturer selling it to advertisers
- gov't getting it and I accidentally trust trigger some alarm
- data getting exposed in a breach
- apps without location access getting it through some means
There's a lot of potential downside and the upside is... my SO knows when I'm almost home?
Yeah, no. Maybe I'll share if I'm doing something risky like hiking alone, but that's never staying on constantly.
