Don’t use shady vpn’s like express, nord vpn. etc. they’re all shit. At the moment I can only reccomend: Mullvad, Proton and IVPN. I would like to disclose that I am a proton subscriber but also a privacy nut that has done a lot of research about this.
I meant at a lot of research abut forgot “lot”. I didn’t mean to imply to have written a research paper. but https://www.privacyguides.org/en/ is a good place to start.
