Seems really cool but it doesn't look open source, there's any security guarantees within the app? I'm really paranoid of where a put my Google account credentials
I'm pretty sure it's modded version of the official youtube app so no guarantees (Just use a dummy account?).
I'm actually very interested in how the vanced developer has made this. This app is pretty much identical to the youtube app with premium features enabled and ad/sponsor bocking/skipping.
I never log into YT on any device. I still get great recommendations and easily stay on top of my favorite channels. IMO the only benefit to logging in is being able to comment.
