YouTube for Android just got a lot better at keeping secrets. The incognito mode the video platform has been testing since May is now rolling out to all Android users. Just like incognito for Chrome, the one for YouTube doesn't log what you watch, keeping your history squeaky clean. To access the feature, simply tap on your avatar to see the new "Turn on Incognito" option, which replaces the Sign Out button. If you choose to switch it on, you'll get a prompt reminding you that your school, employer and ISP will probably still see your activities.
