Google has announced it is changing its privacy policies, combining 60 out of its 70 privacy policies to form a "Main Privacy Policy".

As of March 1st, if you use anything Google, you are agreeing that Google can:
- record search history and patterns
- view the contents of your Gmail emails
- record the videos you watch on YouTube
- view the documents you create in Google Docs for work
- figure out which company you work for and which industry you work in
- allow tracking across all services on all platforms and devices

...and use that information for advertising. As ZDNet says :

"Google will know more about you than your wife does. Everything across your screens will be integrated and tracked. Google noted that it collects information you provide, data from your usage, device information and location. Unique applications are also noted. Sure you can use Google’s dashboard and ad manager to cut things out, but this policy feels Big Brother-ish. Google is watching you as long as you are logged in. It’s also unclear whether this privacy policy move will be considered bundling in some way by regulators. This unified experience hook appears to be at least partially aimed at juicing Google+. Google responded with clarification: Google noted that it already has all that data, but it’s now integrating that information across products. It’s a change in how Google will use the data not what it collects. In other words, Google already knows more about you than your wife."
