It's just a redirect, unfortunately. It simply formats your search to a Google URL query string and redirects you there meaning that it's the same thing as typing it into Google and hitting search. Startpage would be the better option since it uses Google's search anonymously as DDG does for Bing/Oath. You can use !s for Startpage instead of !g for Google. Same results (minus personalized results) as Google, but with the privacy you're looking for.
