DuckDuckGo Doesn't Hide or Encrypt User Search History (blog.searchencrypt.com)

This is an advertisement for SearchEncrypt (whatever that is).

I, uh, want to be able to look at my search history? Local, on my PC, like it is in my browser. If people can see your browsing history, your search history really isn't telling them much more.

Also you can go to Settings -> Privacy and turn off GET requests. With this done the search term is also not shown on the browsers title
