After the recent PRISM scandal regarding widespread surveillance on the web by the US government has opened a can of worms. Now everybody knows that nothing is private, if its on web. There is no absolute way in which you can keep your data absolutely safe. Even the search engines record your every movement on the web.
But unlike other search engines, DuckDuckGo doesn’t keep track of your search activity on the internet. Also, since it doesn’t track your behavior, it does not customize your search results based on what it thinks you might want to see. In effect, you get same search results as everyone else.
Its worth a change. Go for a change, go anonymous! go safe!
