I'm looking for an app to share private photos with various groups across Android & iOS. It should allow to share by groups/albums, full/high-res (not WhatsApp-reduced size) and if possible with servers based in Europe. And it should not be owned or operated by Google, Amazon, Facebook, Apple or Dropbox... Privacy concerns / NSA etc. I've been super happy with BeamIt (https://beamitapp.com/), but they closed some years ago. Before that I used 7moments (https://www.crunchbase.com/organ...#). What's an app/service you guys use for that?
