I’ve been using owntracks for a while now, and while it is pretty decent in terms of accuracy of data collection, it unfortunately lacks in the nice things that make Google Location History so good: automatic clustering, grouping, search, classification of trips and travel methods.

The initial setup is slightly annoying as well. Here’s a small write up from me: https://sathyasays.com/2024/07/13/self-hosting-owntracks-goo...

It doesn't meet your needs, but I have something kind of like this for my iPhone.

I wrote a Shortcuts Automation that triggers when CarPlay disconnects. It then grabs the current date and time, the current latitude and longitude, the street address and an Apple Maps link and appends it to a "Location Log" note in the Notes app. I could've dumped it to a file instead, but I wanted it in a note.

It requires zero interaction from me.

Interested in something similar. Would love to keep a log of locations, especially when travelling, but don’t want Google to be tracking this. A local solution would be awesome.
