Recently Google released Google Dashboard which tells you “what Google knows about you”.

The dashboard lists some of the information associated with the Google services you use: your name, your email address, the number of contacts, the number of conversations in your Gmail inbox, your Google profile, the most recent entries from the web history etc. It’s a long answer to the question: “What does Google know about me?”.

If you have a Google account, you can login to Google Dashboard and you are presented with pretty much everything having to do with Google.

This is actually a pretty useful tool as it gives you a gateway all of your Google services. This is also a great tool for the paranoid because you can see what Google lets you know they know about you.
