People have different privacy concerns. Our goal is to be clear about what information we collect, so that you can make meaningful choices about how it is used. For example, you can:
•Review and control certain types of information tied to your Google Account by using Google Dashboard.
•View and edit your ads preferences, such as which categories might interest you, using the Ads Preferences Manager. You can also opt out of certain Google advertising services here.
•Use our editor to see and adjust how your Google Profile appears to particular individuals.
•Control who you share information with.
•Take information out of many of our services.
You may also set your browser to block all cookies, including cookies associated with our services, or to indicate when a cookie is being set by us. However, it’s important to remember that many of our services may not function properly if your cookies are disabled. For example, we may not remember your language preferences.
I do not think it is meant for harm but good.
