Does blokada-plus create privacy for my whatsapp chats ? and youtube? (privacy-unfriendly apps)

Hi, I’m new to blokada. I want to upgrade to blokada+ VPN for more privacy.
My question: Does this make my identity “private” and “not trackable” in those apps, that have privacy issues, like whatsapp, facebook, youtube, etc? Or, how does it work? Thank you!

Yes and no. It may block connections to sites whose sole purpose is to store data on what you do, but other connections and built-in scripts would probably not be blocked. The normal DNS only blocks most network requests, while the VPN blocks almost all requests.
