I’ve used the search engine DuckDuckGo now and again, and now the search engine, which does not record data on its users, has experienced a surge in use following the NSA revelations:

Gabriel Weinberg noticed web traffic building on the night of Thursday 6 June – immediately after the revelations about the “Prism” programme. Through the programme, the US’s National Security Agency claimed to have “direct access” to the servers of companies including, crucially, the web’s biggest search engines – Google, Microsoft and Yahoo.

Within days of the story, while the big companies were still spitting tacks and tight-lipped disclaimers, the search engine Weinberg founded – which pledges not to track or store data about its users – was getting 50% more traffic than ever before. That has gone up and up as more revelations about NSA and GCHQ internet tapping have come in.

“It happened with the release by the Guardian about Prism,” says Weinberg, right, a 33-year-old living in Paoli, a suburb of Philadelphia on the US east coast. “We started seeing an increase right when the story broke, before we were covered in the press.” From serving 1.7m searches a day at the start of June, it hit 3m within a fortnight.

Yet you’ve probably never heard of DuckDuckGo. “If you asked 100 people, 96 would probably think it was a Chinese restaurant,” as the SFGate site observed. (The name comes from the children’s game DuckDuckGoose, a sort of tag involving seated players.) You won’t find it offered as an alternative default search engine on any browser, on desktop or mobile. Using it is very definitely an active choice, whereas using Google is the default option on most browsers. And 95% of people never change the default settings on anything.

But this 20-person business offers what none of the big search engines do: zero tracking. It doesn’t use cookies or store data about its users’ IP addresses, doesn’t offer user logins, and uses an encrypted connection by default. (Google provides an encrypted connection for logged-in users, but not automatically for non-logged in users.) If the NSA demanded data from DuckDuckGo, there would be none to hand over.

Seeing as how Google (full disclosure, they do cut me a check occasionally for the ads they serve on this site) is determined to drop the word “Don’t” from their motto, “Don’t be evil,” I do wish them all the success in the world.
