The Incognito Page

This is from the incognito page on Google Chrome in which I use:

Going incognito doesn't affect the behavior 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

Notice the last two.
