The majority of the VDT web site is non-interactive. We use a cookie to track aggregate usage using Google Analytics, but we do not use these cookies to collect information about our users.
The one portion of our site that is interactive is our support system, which has URLs beginning with http://vdt.cs.wisc.edu/rt/. Interaction on this part of the VDT web site comes from users who request help in two ways: email to email@example.com and directly opening a ticket on the web page. All of the information about the tickets, including the user's email is publically accessible from our web page.
Individual components in the VDT may have privacy statements associated with them. Here are the privacy statements for VDT 2.0.0, the latest stable release of the VDT:
Other releases of the VDT may have privacy statements associated with them. You can find them by browsing the documentation for older releases.
