Open an Incognito tab (browse in private)

From the Chrome app, tap the Menu icon (at the upper-right corner of the screen), then tap New incognito tab. When browsing in incognito mode, your browsing history, cookies, and cache are automatically cleared once you’ve closed all of your incognito tabs. You still have access to your usual bookmarks and omnibox predictions. Changes that you’ve made to your bookmarks are saved.
