About the app thing. The other day I had to download from the Google play store. The app you search for is NEVER the first app in the resulting list. The first slot is always sponsor slot. I consider myself quite tech literate and I have accidentally installed that sponsored app because I searched for an app (with very specific search terms) and without thought selected the first. Google is one step away from that trope of the moving X button to close the ad. It’s infuriating. Now imagine a tech illiterate trying to get an app.

Putting aside how much of a red flag that is,

Is there any foss self-hosted version of these location sharing services?

Left-handed, left pocket. Just habit I guess. Right side is always keys and headphones.

For temporary stowaways around the house (especially when cooking) it can go in either of the back pockets, depending on which hand I’m holding it with.
