Recall is sometimes fuzzy with age, but it works well enough, and I don't have to worry about external queries violating my various rights nearly as much as with tech companies.
At this point, I think every piece of modern consumer electronics ought to be considered hostile until proven benign. I've worked with enough of them over the years, on different ends, to no longer trust any of them.
I'm also old enough to remember the before-times - when there wasn't the technology to track us everywhere, or, when we did have something breadcrumbing, it wasn't being automatically uploaded to whoever, wherever, etc.
My first question, though, would be "Why?" What value do you get out of tracking your location with any great detail that self hosting it would be of much value? However, various cheap GPS loggers and Google Earth import probably would do a lot of what you're looking for.
