Google Analytics is a way for me to get some general information about the people that visit my website such as the general areas in which they live, what pages they visit, and so forth. No personal information is collected from Google Analytics that can be used by me or anyone else for that matter to know specific details about who you are. Every visitor is a number not a name and is a fair way of gaining insight about the audience of a website.
If you wish to opt out of Google Analytics it is possible to do so with this browser add on.
