Glad to see more interest in privacy focused search, but why not just not contribute to something like duckduckgo that's already doing good work in that space?
As many mentioned, DDG is Bing and Google under the hood. That being said, DDG is great and I’m very thankful it exists.
Shameless Plug: I’m involved in a project called Private Search [1], and we are always interested in partnerships with browsers. Feel free to contact me directly. My email is in my profile!
DDG is the wolf disguised as the sheep. If you consider the vast possibilities a company is able to trace you over the internets it's largely irrelevant where are you coming from, as long as you hop once over a server operated by BigCorp.
And in the case of DDG the results come from Bing. From the rain in the eaves.
