- the Internet domain (for example,xcompany.comExternal” if a private Internet access account is used, or “schoolname.eduExternal” if connecting from a university’s domain) and IP address (an IP address is a number that is automatically assigned to a device when surfing the web);
- the operating system and information about the browser / device used when accessing CDC web pages;

Collection and analysis of this information in the aggregate will help us enhance performance of our application, improve informational materials available within the application, and improve overall customer service. If an e-mail message is sent to CDC or a questionnaire, form, or other online survey found within the mobile application or on the CDC website is completed, CDC will maintain the information in accordance with applicable federal law.
CDC does not disclose, give, sell, or transfer any information about CDC website visitors or users of our mobile applications unless required for law enforcement or otherwise required by law.
For site security purposes and to ensure that this service remains available to all users, CDC employs software programs to identify unauthorized attempts to upload or change information, or otherwise cause damage.

CDC web pages use two types of “cookies”: session-based and persistent. The majority of cookies used are session-based. These bits of information are stored temporarily in your device’s random access memory (RAM) as a line of text. When you close your browser, the cookie is destroyed and no trace of it remains on your hard drive. These session cookies are used solely as a method to improve the user experience for those visiting the site. In very few cases, the CDC website uses persistent cookies to store information for a longer period. In those cases, the web page is clearly noted and the user can choose not to use that web page feature. As noted above, in no case does CDC disclose, give, sell, or transfer any personal information about CDC website visitors unless required for law enforcement or otherwise required by law.
