Our Mission! Doodo began as an idea for a better search engine experience. We decided to make a bold move and show accurate search results and not save search history. We told the world “Others tracks and sell your data ". We want to improve in design and not make you want to close your browser the second you see our results page. Many people believe that you simply can't expect privacy on the Internet. We disagree and have made it our mission.
