Isn’t Chrome Google, and therefore any variant of Chrome also Google? Would it be beyond belief to assume that the “privacy” versions of ANY browser (i.e. - Chrome, Firefox, Brave, Edge) or app (i.e. - WhatsApp) either has a back-door for, or is run by, the intelligence community?
Granted, you're never 100% secure or private on the internet. But you improve your chances if you avoid Google Chrome or MS Edge.
Brave and Firefox (which is non-Chrome) are some of the better privacy browsers.
As for search engines, DuckDuckGo has gotten a lot of press as a good privacy alternative to Google or Bing, but I recently read that Qwant is even better.
