While the exact implementation varies from browser to browser, what private browsing modes have in common is that once you close your private browsing window, your browser no longer stores the websites you visited, cookies, user names, passwords and information from forms you filled out during that private browsing session.Įssentially, each time you open a new private browsing window you are given a “clean slate” in the form of a brand new browser window that has not stored any browsing history or cookies. In fact, a recent lawsuit against Google alleges that internet users are not getting the privacy protection they expect when using Chrome’s Incognito mode. Other studies conducted by the Pew Research Center and the privacy-protective search engine company DuckDuckGo have similar findings.
