Browse YouTube while incognito on iOS and Android
When logged in to the YouTube app, you can now turn on incognito to browse in a session that will not be influenced by or reflected in your signed-in search and watch history.
How to browse incognito
As you browse, a persistent reminder in the form of a black bar will appear at the bottom of the screen to remind you that you are incognito.
What happens while browsing incognito
While incognito, the YouTube app behaves as if you aren't signed in to your account. This means that your YouTube experience won't be influenced by any of your signed-in activity, such as videos watched, searches or subscriptions.
When you turn off incognito, your search and watch history is cleared. You'll return to the last account that you used before turning on incognito, and none of your incognito session activity will be reflected on your account.
If you're inactive for more than 90 minutes, your incognito session will end and you'll be returned to the last account that you used. The next time that you open YouTube, you'll see a message letting you know that you're no longer incognito.
Everything you do while in incognito mode is private, so when you attempt to take a public action, like commenting, subscribing or liking, you'll be prompted to turn off incognito to complete that action using the account last used.
