OneSearch is literally just Bing results flanked by ads that don’t track you
despite being from a company that makes money tracking you [1].

According to the OneSearch privacy policy, search results will only be
personalized based on location, which it will collect from IP addresses.
OneSearch says that it will separate IP addresses from users and their search
results [2].
