The main idea here is that for years I hade 24/7 shared location with trusted circle of people, so that I have a chance of getting help in case something goes significantly sideways on my (mountain) adventures.
And as #GoogleMaps is getting less and less useful, I thought that finding an alternative for this one use-case should be easy.
It is not. All the solutions I've found have questionable ideas about data processing or steep pricing model or vendor lock-in or all of the above.
So I thought that for folks with similar needs I should build easy(tm) to start & operate alternative.
