Whatever its stores and however it stores it doesn’t matter to me: I moved its storage space to my ~/.Private encrypted directory. Same thing for my browser: I don’t use a master password or rely on its encryption because I set it up so it too saves my profile in the ~/.Private directory.
See here for more information. You can essentially secure any data saved by any app with eCryptfs - at least when you’re logged out.
Linux-only of course. In Windows… well, Windows.
The NewPipe team deserve a Nobel Prize. It might look like an unimportant video player, but it’s one of the last bastion of resistance against he Google monopoly and monoculture, the total invasion of advertisement in every corner of our lives, the privacy violation that always come with Google, and the general enshittification of the internet.
Thank goodness for NewPipe…
