Automatically Generated Information
Sigma gathers certain broad information about Site use, including the number of unique visitors, the frequency with which they visit, and the programs and services preferred. We gather this information automatically so that we can, for example, learn how many people visit the Site, see which pages are the most and least viewed, and identify which web sites are referring visitors to the Site and related information. The data helps us determine the extent to which visitors use certain parts of the Site and tailor the Site in the future. In connection with these activities we may use some of the following tools.
IP Addresses: We collect and analyze traffic on the Web Site by keeping track of the IP addresses of our visitors. An IP address is the unique numeric identifier assigned to each computer browser accessing the Internet. An IP address, by itself, cannot identify you personally. However, when combined with other information provided by your Internet Service Provider (ISP), your IP address can be used to identify the computer originating a message.
