I work for a company that writes several webapps that deal with a lot of sensitive information, such as full name, date of birth, address, and SSNs. Currently we don't have anything to measure site usage, but I would like to use Google Analytics to track usage and statistics about our users.
What data is sent to Google when you use Analytics? If I put this on a page that contains any of the above information, will that data be sent to Google? Or are they just getting the necessary information like user agent and IP address?
