Hi thanks for fast answer !

I already have a amnesic OS with Tails for travel.

I choose the Live-USB option for unplug my OS/files and use it on any device like you said.

I'll use Debian or Artix or maybe TTY (why not LOL).

Nowadays if you want privacy I think the best way is to have Live USB (but the ultimate safest way to have total privacy is simply not be connected at all and totally Off The Grid but that's another topic :) )

Thanks you again for your answer !

PS : do you know any spotify or netflix like .onion ?
