Respondent privacy is of the utmost importance within the DHQ III system. Researchers do not provide the National Cancer Institute (NCI) or the DHQ III system with any personally identifiable information (PII) associated with study respondents. Rather, researchers specify a user ID for each respondent and download system-generated login credentials that respondents use to access DHQ III. Additionally, this information and the information described below will not be disclosed unless required by law.

The DHQ III system also does not capture any personally identifiable data from Respondents. Respondent data are protected using industry standard security controls. The communication between the DHQ III server and the respondent’s computer and all data entered into the DHQ III system database are encrypted.

Limited information about the use of the DHQ III system is collected automatically, primarily for monitoring the software's performance and usage patterns. This information is helpful when troubleshooting bugs and considering future updates and improvements. The following information about DHQ III user access is collected and stored automatically:

  • date and time of access
  • type of browser
  • operating system
  • screen resolution
  • IP address -- often the IP address is that of the user's Internet Service Provider (ISP)

DHQ III also uses session cookies to facilitate session maintenance and seamless navigation through the web site. This type of cookie does not permanently collect or store information and any contained data is automatically destroyed shortly after the browser is closed.

To help protect your privacy, it is recommended that you log out and close your browser when you are finished with a DHQ III session.
