If only osm had better search and complete addresses...
Can I set the sharing to permanent?
I too was trying to find alternatives to these services but I could not.
I saw a github "thread" ones for organic maps, but it did not get traction... They could make it a paid service as that are trusted by the community to handle that data.
There was a new application, I do not remember the name of it... But it was using google play services which I did not add to my OS.
I found the app through howtomen's YouTube channel, let me know if you need it, I will search for it.
Edit: If you have the skills, you could setup/self-host owntracks, which I could not do, securely.
And you'll just re-hit the red button.
Which one is the Greek community? Those that I found are dead.
Much better, thanks.
You carry this community alone!
Is that confirmed though?
FYI, grapheneos primary aim is security and not offering a degoogled os. The community generally even prefers installing applications through google play, which someone may choose to install.
