Alternatively referred to as Private Browsing, InPrivate Browsing, and Private Window and informally as porn mode, Incognito is a mode that prevents any information from being stored locally. For example, when you visit any web page the text, video, etc. that is loaded is stored on the computer. In addition, any searches or forms that are filled out are stored in AutoComplete fields.
Note: While in Private or Incognito mode nothing is stored to your computer, however, this does not mean you are anonymous on the Internet. Each page that you visit still recognizes your IP address. Therefore, if someone had the legal abilities to track you using your IP address an ISP, website, and even a search engine server log may contain your IP address, which could be tracked.
