Like many Web sites, the Service's Web site servers generate log files. These logs record aggregate (non-personally identifiable) information about site usage such as Internet protocol (IP) addresses, browser types, Internet service providers, referring/exit pages, pages accessed, platform types, date/time stamps, times of use, and page views, for example. This information is necessary to analyze trends, administer the Service's Web site, balance web traffic, evaluate users' electronic browsing in the aggregate, and gather broad demographic information for aggregate use.
