Search Data, The Most Personal Data
It's a long known secret that Google and other notable search engines, track all users' activities to uniquely identify them. Their policy in which users agree in order to use their services, are deliberately isolating people out of their own personal space.
As one of the most appealing Google alternative, DuckDuckGo is a search engine that doesn't track its users. What it does, almost mirrors other search engines except for one thing: it doesn't save any information about its users.
