Google is preparing for changes in its privacy policy beginning March first. The company says it plans to replace more than sixty separate policies for different products with one main policy.

Privacy activists criticized last month's announcement. They are concerned that the new policy will make it easier to track the activities of users across Google's many products -- from Gmail to YouTube.

Marc Rotenberg heads the Electronic Privacy Information Center in Washington. He says Google's aim is to create a single unified profile of its users.
