I’m using this docker container for some years: https://github.com/haugene/docker-transmission-openvpn Works well with my lifetime FastestVPN which I got for a few bucks some years ago.

Its not for privacy, but for deniability. I wouldn’t “trust” any traditional VPN.

Got a lifetime subscription for FastestVPN some years ago. Its slow, but it works and is unlimited so 🙆‍♂️

You’re talking about Android (Linux) phones, and not GNU/Linux as stated in the question.

I just use Transmission in docker and VPN with killswitch. Done.
