There is no privacy on chromium, it phones home to Google a lot and those communications are encrypted so you will never really know what data is being sent but assume Google can link everything you do in Chromium to you.
Users who think they are "ungoogling chromium" are fooling themselves.
All the commercial browser reeleases like Mullvad browser, Brave or duckduckgo browsers are just window dressing.
Firefox or its children really are the only option.
