Incognito mode, or sometimes called private mode by various browsers, is basically a means to provide some level of anonymity for users while browsing the Internet. These browsers such as Google Chrome, Mozilla Firefox, and Safari accomplish this by making sure all of the information that you are viewing and entering onto the website is not stored on your machine. Essentially, running in incognito mode disables storing of browsing history, cookies, site data and forms you've filled. This way, the user ensures that whatever content they are viewing cannot be later found from searching on the same machine they're using.
