Incognito mode — also known as "private browsing mode" — is a sneakier way to use the internet.
When you browse the internet with incognito mode on, you won't leave any trace on the device you're using. Your browser won't save your browsing or search engine history, and won't remember what sites you've logged into — or even what your username and password is.
It's great if you share your computer or phone with other people, since no one else will be able to see what you've done once you close the window.
Important: Incognito mode keeps you safe locally, but your browsing history will still be visible to your internet provider, and websites you visit will know you're there. And if you're using a Wi-Fi network powered by your work, school, or a business, they can track it too.
