@carlsbad2 projecting much today? Qobuz is pretty clear about this. They even have a cache locally, so once you have listened to a song it is stored locally, ready for to listen to again....
It's readily available to learn about on their support site.
Tidal is the same, also available on their support site.
In summary, yes, you actually do not stream music from Tidal or Qobuz, you download and then playback.
