Information You Give Us
The CDC Privacy Notice that follows is applicable to www.cdc.gov, as well as most CDC websites, and its mobile and voice applications. If a different Privacy Notice is used by a CDC website, you can find a link to it in the footer at that web page. CDC does not collect Personally Identifiable Information (PII) when you use its digital media from your computer or mobile device unless you choose to provide that information to us.
Visits to CDC.gov:
While using the CDC’s digital media, certain information will be gathered and stored about your usage of the digital media. This information does not identify you personally. We collect and store only the following information:
- The Internet domain name (for example, “xcompany.com” if a private Internet access account is used, or “schoolname.edu” 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)
- Information about your computer or mobile device (e.g., type and version of web browser, operating system, screen resolution, and connection speed)
- The number of times CDC’s digital media was accessed
- The pages or screens accessed or visited on CDC’s digital media
- The visit date and time
- If www.cdc.gov is designated as a home page (in the event your mobile device allows this functionality)
- The internet address or URL of the website visited immediately prior to visiting CDC’s digital media, but only if you connect to CDC.gov via a link from any web page within that website
Collection and analysis of this information in the aggregate will help us enhance performance of our digital media, expand informational materials available through digital media, and improve overall customer experience.
Using CDC’s Mobile & Voice Applications
When you use CDC’s Mobile and Voice Applications (Apps), certain information will be gathered and stored about your usage of that App. This information does not identify you personally. We collect and store information as follows:
- CDC receives aggregate data about the use of our Apps, such as the number of times the applications have been opened or the interactions or actions completed in the application. This is gathered via a third-party provider (please refer to the tools list). We also receive aggregate data from the platforms that distribute our Apps to various app stores (please refer to the tools list), such as the number of people who download the App and mobile set-up information (e.g., device model, App version, country, language, and mobile carrier). We do not, however, receive information unique to you or your use of our Apps.
- You may sign up to receive “push notification” messages via a third-party provider (please refer to our tools list). To make sure messages reach the correct devices, our third-party provider relies on a device token unique to your mobile device. A device token is a unique identifier issued to the app by the operating system of your mobile device. While we may be able to access a list of the tokens, neither the App nor the tokens will reveal your identity, your unique device ID, or your contact information to us. The third-party provider may collect the following: the time of an event, how a User came to our site, what search engine and search keywords users may have used to get to our site, information about the device our user is on such as their Operating System, and browser, as well as the city, region and country location of users. This location information enables CDC to send public health push notification messages that are relevant to certain geographic locations. If, at any time, you wish to stop receiving push notifications, simply adjust your phone settings or remove the App. Please consult the privacy policies of these third parties (please refer to third-party tools list ) for further information.
CDC does not disclose, share, sell, or transfer any information about CDC digital media visitors or users 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’s digital media are maintained by the U.S. Government and is protected by various provisions of Title 18, U.S. Code. Violations of Title 18 are subject to criminal prosecution in Federal court.
If you choose to provide your personal information to CDC via its mobile application or the CDC website – for instance by sending us an e-mail message or completing a questionnaire, form, or other online survey found within the mobile applications or on the CDC website – CDC will handle, use and maintain the information in accordance with all applicable federal laws. Learn more about how we handle personal information that is sent to us.
CDC uses social media and third-party (non-CDC) websites to share public health information and to engage the public. Your activity on those sites is governed by the third-party website’s security and privacy policies.
