It says this right on the OP's link: "Vivaldi has always honored its users’ rights to data privacy and protection. There is no need to collect your personal information. We don’t track you. Period.
We encourage users to explore privacy-conscious options and educate themselves on the basics of web browser security. This year we integrated DuckDuckGo as our default Private Search, and added Qwant to the list of suggested search engines (which includes StartPage as well). All of these are great tools for taking back your privacy. We’re continuing to explore ways to protect Vivaldi users and this will always be a top priority."
