Quick question why are you so sure that startpage, duckduckgo or brave are not tracking your data ? As far as I'm concerned they need to make money too there is no such thing as free shit. Also even if they are more private and don't track your date if the search is not giving the results you want/need it's not really a good search engine, I'm saying this as a few years back I tried duckduckgo and it was so bad at that point at giving results I wanted/needed that even bing was doing a better job.
