Oh Google, you keep making me laugh.... So I opened an Incognito browsing window. Yes, I like my privacy when checking my e-mail...thank you very much. And this is what I read:
You've gone Incognito. Pages that you view in this window won't appear in your browser history or search history and they won't leave other traces, like cookies, on your computer after you close all open Incognito windows. Any files that you download or bookmarks that you create will be preserved, however.
Going Incognito doesn't affect the behaviour of other people, servers or software.
Be wary of:
-Websites that collect or share information about you
-Internet service providers or employers that track the pages you visit
-Malicious software that tracks your keystrokes in exchange for free smileys
-Surveillance by secret agents
-People standing behind you
The 4 clause made me paranoid, but the 5 one just cracked me up!
