This browser consumes about same amount as chrome in my tests. Maybe 1/5 more.

Firefox and Chrome also collect the same information, but it is an opt-in from what I remember.

Edit:

Installed Chrome extensions are your remaining helpers in there.

Uhm, reference? I seriously doubt that...

Well, first from https://vivaldi.com/privacy/ it's not clear to me whether the privacy thing applies to the browser or the vivaldi web site.

Second, here's google chrome's privacy policy:

https://www.google.com/chrome/browser/privacy/

You can see that they have all kinds of information being sent to google. At least as much as Vivaldi.
