I don't think OpenStreetMap is quite there yet. I'd use Google maps if I were you and when I find something I want, I'd make a contribution to OSM.
With that said:
- Google maps can be used whilst being signed out (as incognito).
- If you're running a rooted device and have access to a work profile, maybe install MicroG in that profile. Then, install the maps apk.
- Run a VPN client in the work profile too, so Google associates your traffic with a different IP. Rotate your VPN box/VPS/Public IP of VPN to keep Google out of the loop. Of course, Google does check for your behavioural patterns so this isn't exactly foolproof, but it is the closest one can get without modifying source-code.
- Note that from Android 14, you no longer cease operation of the work profile when you hit pause. You just suspend the partition. Which is fine, I suppose, but a detriment of this approach is that most apps have network access. Luckily, one can install a firewall and deal with the problem.
I fully support OSM and would like to contribute when and if I go out, but if you're in a tough spot, I'd rather you use Google maps and be safe rather than using something that may or may not be as reliable and get stuck in a messy situation.
Cheers
