Personally, I use GPSLogger from FDroid on a 15 minute ping interval and then load the files into Location Map Viewer (also FDroid) for my own location tracking. Disabled Google awhile ago.
I back the files up to a home NAS.
Have you heard of OwnTracks? It’s a self hosted google timeline alternative.
If you have ever lost something and had to retrace your steps it helps but I guess it’s not super important or relatable for most people
Looks like most of the existing replies captured my same use cases!
There have also been a couple of times where my wife and I disagreed about what we did on X day and it’s kind of nice to see who is right 😂
I think I also just like the raw data. I also keep spreadsheets of my utility bills over time, for example, because it’s weirdly fun to look back and see or compare.
One thing I’d really love is a self-hosted all-day heart rate tracker, but have yet to stumble on such a thing.
With that measure in place, what likelihood do you think Google still knows your location?
4G masts can triangulate your location quite well based on signal strength and which post you’re currently connected to so unless people are planning on removing their sim the government will always have decently accurate localization.
