Standard server log information, such as IP address, time spent on the site, browser type, etc., is collected and assessed on an aggregate, rather than individual, basis in order to track site statistics, data that are most popular to our visitors, performance monitoring, and troubleshooting. Studying access statistics and usage patterns helps to project future hardware needs, and aids in the design of new functionality. We also use this information for site and system security. When you sign up for an OpenTopography account, we ask you for personal information (such as your name, email address, account password, etc). This information is stored on secure OpenTopography servers. We do not share server log and user account information with third parties for marketing or other purposes. Aggregate usage information may be shared with our data provider partners to allow them to quantify usage of their data.
