I checked this app out with Microsoft, they said that this is a bogus app it is not an authentic Microsoft search app. Also it has been modified to collect your search information, your IP address, your location, and your ISP. They told me not to use it. The safest way to use Bing is go to https://bing.com
I am curious who you checked with in Microsoft. Just Bing the names of the authors or look at the official Bing blog (http://www.bing.com/community/blogs/search/archive/2009/06/11/bing-and-your-browser.aspx)
