Incognito mode is less private than DuckDuckGo. All Incognito mode does to “protect your privacy” is not store your browsing history locally and clears your cache from cookies.  It doesn’t block trackers, so any third party can lurk on your online whereabouts. Also, it doesn’t hide your IP address; thus, your identity is within everyone’s reach. In fact, incognito mode is not so incognito.
