Apparently they've been scraping Apple's network location database and plan to offer a substitute service running on GrapheneOS servers, as well as a way to upload data you collect on your device.
I worked on this a while back in parallel. You can dump Apple's entire database in ~2 weeks. Around 3 billion records including China.
You can compress it down to only a few gigs and have everything offline. I also got a ichnaea proxy though not as well tested. Been using it myself and it's alright,
