DuckDuckGo is actually somewhat more private than Startpage. Startpage is officially a Google partner, so it is not 100% clean; some user identifiable information (specifically, your IP address) is sent to Google.
DuckDuckGo (Wikipedia)IxQuick/Startpage (Wikipedia) Hmmmmm, interesting. Two questions:
1. If only the IP Address is sent to Google, of what use is that set of numbers to them?
2. The Wikipedia article was quite supportive of DuckDuckGo.
I'm not one to change horses midstream but I am having a problem getting StartPage on Safari in my wife's account. I assume, if I was to elect to go with it rather than Startpage, it'd simple be a matter of choosing DuckDuckGo in the Preferences in both her account and mine. Yes?
Edit: Okay, make that three, er, four questions.
I notice that, while neither StartPage nor IxQuick leave cookies, they do leave caches. Should I care? Any downside in removing them?
