Actually, it's weaker than the guest mode because a guest doesn't get any local identity to represent a user at the first moment. The incognito mode may take some insensitive configurations in their user profile mostly for convenience but in an isolated manner. I think it still could be named better like "private mode" used in some other localization, though.
