When you place a data order, your personal contact information (email address) is stored forever in our log files. This information is used in several ways. The domain name of your email address is used in aggregate to track what types of users are ordering data, e.g. educational/government/etc, U.S./Europe/etc. These statistics do not identify individual users, and are included in our institutional annual report.
Email addresses are used individually to notify users of important updates or problems with the data they ordered. In addition, dataset creators and funding agencies may be provided with lists of email addresses for users who ordered their data.
Individual email addresses are identified in summary reports about the data system. These reports are only available to data system personnel and are not made public.
