What happens while browsing incognito
While incognito, the YouTube app behaves as if you aren’t signed in to your account. Your account activity, like your subscriptions or watch history, won’t influence your YouTube experience.
When you turn off Incognito, your search and watch history from your Incognito session is cleared. This means that none of your Incognito session activity will be reflected on your account. You’ll return to the last account you used before turning on Incognito. Also, if you’re inactive for more than 90 minutes, your Incognito session will end. You’ll then be returned to the last account you used. The next time you open YouTube, you’ll get a message letting you know that you’re no longer Incognito.
Everything you do while in Incognito mode is private. When you try to do something public like commenting or subscribing, you'll be asked to sign in to complete that action.
