+Within the CDC, we restrict access to personally identifiable information to employees, contractors, and vendors subject to non-disclosure requirements who require access to this information in order to perform their official duties and exercise controls to limit what data they can view based on the specific needs of their position. If you choose to share information with us, we may in some cases, share that information or automatically generated information with other government agencies in response to lawful law enforcement requests or to protect CDC.gov from security threats.
+### Using CDC's Mobile Application
+When you use CDC's Mobile Applications (Apps), certain information will be gathered and stored about your usage of the 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 [third-party tools list](http://www.cdc.gov/other/third-party-pages.html)). We also receive aggregate data from the platforms that distribute our Apps (currently the iTunes Store, Google Play Store, and the Windows Store), 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). Please consult the privacy policies of these third parties for further information.
+- You may sign up to receive "push notification" messages via a third party provider (please refer to the [third-party tools list](http://www.cdc.gov/other/third-party-pages.html)). 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 the mobile device. While we may be able to access a list of the tokens, the App and tokens do not reveal your identity, unique device ID, or 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.
+CDC does not disclose, share, sell, or transfer any information about CDC digital media visitors or users unless required by law enforcement or by statute.
+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.
+### Email Subscriptions
+Email and text message subscription services are offered by CDC as a convenience to users who choose to receive information via these channels. All information published via email subscriptions and text messaging services is available on CDC.gov without the requirement to provide email address or phone number.
+In order to manage CDC email subscription lists, we retain the names and email addresses of our email subscribers, as well as other information they may have shared with us (e.g., addresses and phone numbers), logs of emails we send, and automatically generated email data used to improve our email communications. Email subscriber service providers may collect and provide non-identifying information about the number of messages sent, clicks and open rates.
+To get more information about current email subscription service providers and their privacy policy, please refer to the [current third-party tools/pages list](http://www.cdc.gov/other/third-party-pages.html). The email subscriber information is secured and only available to CDC managers, members of the CDC's communication and web Teams, and other designated staff who require this information to perform their duties. If, at any time, you wish to stop receiving our messages, simply click on the "Unsubscribe" link at the bottom of each email message.
+### Survey Tools
+Invitations to CDC surveys are sent via a pop up or external links to a random sampling of visitor. Your acceptance of a survey is completely optional. If you decline any survey, you will still have the same access to the information and resources provided in all of the CDC's digital media channels, as those who opt to take a survey.
+CDC uses online surveys to collect opinions and feedback from visitors on all type of digital media channels. Please refer to the [current third-party tools/pages list](http://www.cdc.gov/other/third-party-pages.html) for the current survey service providers. These survey service providers obtain feedback and data on visitor's satisfaction on behalf of the CDC. Surveys conducted on behalf of the CDC do not collect any Personally Identifiable Information (PII), and the aggregate results are only available to CDC staff (e.g., subject matter experts, health communication staff, and other designated staff) who require this information to perform their duties.
+Mobile surveys (i.e., those accessed via your mobile device) may request an email address and a phone number from you in order to send an external link to the survey. CDC does not receive your personal information, nor will the CDC have access to your information. To get more details on the data collected by any of these survey service providers, please refer to their specific privacy policy.
+### Official CDC Presence on Third-Party Websites
+All official CDC information available on third-party websites is also available on CDC.gov site. The CDC maintains official pages or accounts on third-party websites in order to better engage and communicate with the general public ([a current third-party tools/pages list](http://www.cdc.gov/other/third-party-pages.html) is here). Your activity on those sites is governed by the third-party website's security and privacy policies. Users of third-party sites often share information with the general public, user communities, and/or the third-party operating the site. Consequently, you should review the privacy policies of third-party sites before using them and ensure that you understand how your information may be shared and used. You should also adjust privacy settings on your account on any third-party site to match your preferences.
+For the sole purpose of complying with the [Presidential Records Act](http://www.archives.gov/about/laws/presidential-records.html), the CDC archives some information that users submit or publish when engaging with the CDC through official CDC pages or accounts on third-party websites (e.g., by sending a message, posting a comment, "following," "friending," or taking similar actions). This information may contain personal information, such as an individual's username and other public account information, when such information is available based on the user's privacy settings and the terms of the site. For example:
+- On Twitter, the CDC automatically archives "tweets" from official CDC accounts, "direct messages" sent to or from official CDC accounts, and "mentions" (tweets from other users to official CDC accounts; these tweets contain an @ and the username of an official CDC account (e.g., [@CDCgov](https://twitter.com/cdcgov)). The CDC also automatically archives any status that official accounts have "favorited."
+- On Facebook, the CDC archives all content created by official CDC pages, content that tags an official CDC page, and any content posted on official CDC pages (for example, the number of likes to the page and comments posted).
+- On Google+, the CDC archives all content posted by official CDC accounts, as well as the number of likes/comments/shares on each of those posts (including the comments themselves). The CDC also automatically archives the total number of Google+ users that have added our page to a "Circle," and the list of users that CDC accounts have added to "Circles."
+For aggregate statistical analysis and to improve the quality of our services, we may integrate web measurement tools with our social media pages. To see current list of web measurement tools, please refer to the [current third-party tools/pages list](http://www.cdc.gov/other/third-party-pages.html). These tools enable basic analysis of social media traffic (such as the number of people visiting a certain page) and do not collect personally identifiable information.

+## How Information is used
+If you choose to [provide us with information](http://www.cdc.gov/Other/privacy.html), we may use that information to contact you, respond to your message, or provide you the information or services you requested. In order to serve you better, we may analyze multiple sources of data you have provided (for example, to look up whether you previously contacted the CDC about the same topic so that we do not send you a duplicative response). We may also use messages or comments collected through CDC.gov sites, Apps, or official social media pages for our own purposes, such as to inform policy decisions or in public advocacy.
+We may use data you provide and automatically generated data for statistical analysis to assess, for example, what information is of interest to users, technical design specifications, and system performance. This allows us to make general improvements to our site as well as to offer tailored content to email subscribers (e.g., a follow-up message to subscribers interested in a specific topic based on information they have provided or automatically generated data).
+[Top of Page]()
+## Sharing of this Information
+[Information you choose to share with the CDC](http://www.cdc.gov/other/privacy.html) (directly and via third party sites) may be treated as public information. We may, for example, publish compilations of messages or comments collected through CDC.gov or official social media pages and provide them to national leaders, members of the press, or other individuals outside of the Federal Government. However, we exercise discretion to limit such disclosures to protect your privacy (for example, we generally do not publish last names of commenters).
+The CDC uses a third-party analytics provider (for current provider please see [current third-party tools/pages list](http://www.cdc.gov/other/third-party-pages.html)) to collect and summarize this information in conjunction with cookies. The third-party analytics provider does not receive personally identifiable information through these cookies and is prohibited from combining, matching or cross-referencing CDC.gov information with any other information.
+Within the CDC, we restrict access to personally identifiable information to only those employees, contractors, and/or vendors who require access to this information in order to perform their official duties and exercise controls to limit what data they can view based on the specific needs of their position. If you choose to share information with us, we may in some cases share that information (or automatically generated information) with other government agencies in response to lawful law enforcement requests or to protect CDC.gov from security threats.
 We do not use or share your information for commercial purposes and, except as described above, we do not exchange or otherwise disclose this information.

+## Web Measurement and Customization Technologies
+## Data Retention
+All uses of Web measurement and customization technologies will comply with existing policies with respect to privacy and data safeguarding standards. Information Systems owned and operated by CDC are assessed using Privacy Impact Assessments (PIAs) posted for public view on the Department of Health and Human Services (HHS) Website (http://www.hhs.gov/pia/). Groups of records that contain information about an individual and are designed to be retrieved by the name or other personal identifier linked to the individual are covered by the Privacy Act of 1974, as amended (5 U.S.C. Section 552a). For these records, CDC Systems of Record Notices are published in the Federal Register and posted on the CDC Web site at: [http://www.cdc.gov/SORNnotice](http://www.cdc.gov/SORNnotice)/.
+Submitting personal information (name, address, telephone number, email address, etc.) is voluntary and is not required to access information on our website. However, if you choose to provide CDC with personally identifiable information -- for example by completing a "Contact Us" form, leaving a comment, sending email, or completing a survey -- we may use that information to respond to your message and/or help us get you the information or services you requested.
+CDC Websites use a variety of different Web measurement and customization technologies to collect and analyze the information with regard to users' visits. Some pages on CDC.gov may include web content or functionality from third parties. For example, content or functionality from the following third parties may be present on some CDC.gov pages, including but not limited to:
+We retain the information only for as long as necessary to respond to your question or request. Information submitted electronically is maintained and destroyed as required by the Federal Records Act and records schedules of the National Archives and Records Administration. It may be subject to disclosure in certain cases (for example, if required by a Freedom of Information Act request, court order, or Congressional access request, or if authorized by a Privacy Act System of Records Notice (SORN)). It is subject to the Privacy Act if maintained in a Privacy Act system of record.

+For more information, see:
+CDC uses online surveys to collect opinions and feedback from a random sample of visitors. CDC.gov uses the ForeSee Results' American Customer Satisfaction Index (ACSI) online survey to obtain feedback and data on visitors' satisfaction with the CDC.gov Website. This survey does not collect personally identifiable information. Although the survey invitation pops up for a random sample of visitors, it is optional. If you decline the survey, you will still have access to the identical information and resources at the CDC.gov site as those who do not take the survey. The survey reports are available only to CDC.gov staff, such as subject matter experts, health communication staff and other designated staff who necessarily require this information to perform their duties. CDC retains the data from ACSI survey results as long as needed to support the mission of the CDC.gov Web site, but for no longer than one (1) year. ForeSee's privacy policy is available at: [http://www.foreseeresults.com/privacy-policy.shtml](http://www.foreseeresults.com/privacy-policy.shtml)

+CDC uses GovDelivery to send e-newsletters, alerts and other messages to visitors who subscribe to them. To subscribe to a CDC product, you must provide an email address and indicate your subscription preferences, including the items you want to receive. The email subscriber lists are password protected by GovDelivery. Only the CDC managers who send newsletters, alerts or memos via GovDelivery and staff members who monitor the results of GovDelivery email initiatives have access to the subscriber lists. GovDelivery never allows access to the subscriber lists to anyone outside of CDC for any purpose. GovDelivery collects and provides non-identifying information about the number of messages sent, clicks and open rates. This information is password protected and only available to CDC.gov managers, members of the CDC.gov Communications and Web Teams, and other designated staff who require this information to perform their duties.

+## Use of Cookies
+## Third-Party Tools and Sites
+The Office of Management and Budget (OMB) Memorandum M-10-22, _Guidance for Online Use of Web Measurement and Customization Technologies_ (June 25, 2010), (_available at_ [http://www.whitehouse.gov/sites/default/files/omb/assets/memoranda\_2010/m10-22.pdf](http://www.whitehouse.gov/sites/default/files/omb/assets/memoranda_2010/m10-22.pdf)) allows federal agencies to use session and persistent cookies. When you visit any Web site, a small text file called a "cookie" may be placed on your computer. The "cookie" allows the server to "remember" specific information about your visit while you are connected to that Website. The cookie makes it easier for you to use the dynamic features of Web pages. Cookies from CDC Web pages only collect information about your browser's visit to our site; they do not collect personal information about you.
+CDC content gets published on third-party sites as a convenience to users who prefer to use these channels. All information published on these third-party sites is also available on CDC.gov site.
+CDC uses two types of cookies on its Websites: single session (temporary) and multi-session (persistent):
+### Links to External Sites
+- Session Cookies: We use session cookies for technical purposes to improve the user experience while visiting our Website. Session cookies are temporary text files that expire when you leave our Websites. Once you close your browser, the cookie is destroyed and automatically deleted from your computer. Under OMB M-10-22, our use of session cookies is defined as Usage Tier 1 single session. The policy states that this tier encompasses any use of single session Web measurement and customization technologies.
+- Persistent cookies are stored on your computer for a longer period. These multi-session cookies are stored on your computer and expire 1 year after your last visit to a Website. After 1 year, they are automatically deleted from your computer; however, you may also choose to delete persistent cookies from your computer at any time. We use persistent cookies to collect non-PII data about users who frequently visit our Websites, and to test variations of our site design and content to optimize our Web pages. In the Office of Management and Budget (OMB) Memo 10-22 Guidance, our use of persistent cookies is defined as "Usage Tier 2 Multi-session without Personally Identifiable Information (PII)," which "encompasses any use of multi-session Web measurement and customization technologies when no PII is collected."
+CDC.gov pages and other CDC digital media platforms may link to websites created and maintained by other public and/or private organizations and individuals. When you follow a link to an external site, you are leaving CDC.gov and are subject to the external site's privacy and security policies. We do not control or guarantee the accuracy, relevance, timeliness, or completeness of information contained on an external site. We also do not endorse the site's sponsor, any views they express, or any products or services they offer.

+### CDC Pages on Third-Party Websites
+## You Can Opt Out or Disable Cookies
+Your activity on third-party sites ([a current list is here](http://www.cdc.gov/other/third-party-pages.html)) is governed by the third-party website's security and privacy policies. Please contact third-party site's Privacy Office if you have any questions or need further information.
+If you do not wish to have session or persistent cookies placed on your computer at all, you can choose not to accept cookies from the CDC Website by changing your browser settings. By not accepting cookies you will still have access to all information, and resources on our Websites, identical to that received by individuals choosing to accept the cookies. Instructions to opt out or disable cookies using some of the most popular browsers are available at [http://www.usa.gov/optout\_instructions.shtml](http://www.usa.gov/optout_instructions.shtml).
+### CDC Content Embedded in Third-Party Sites
+ [Top of Page]()
+In some instances, CDC's content may be embedded on third-party websites as a way to increase public awareness of CDC activities (for example CDC's Content syndication, microsite, data widgets, etc.). The integration of these products is intended to provide a seamless user experience and to enhance users' ability to access public information provided by CDC. The embedded CDC.gov content automatically generates CDC server logs, web metrics and may set a CDC cookie (see [Cookies](https://www.cdc.gov/other/cookies.html)). Additionally, all other cookies, web metrics and server logs etc. are governed by the third-party website's security and privacy policy.
+## If You Send Us Personal Information
+[Top of Page]()
+You do not have to give us personal information to visit the CDC Websites. If you choose to provide us with additional information about yourself, as in an e-mail message, questionnaire, form, online survey, or other tool, submitted through our website, we only use that information to respond to your message.
+## Interaction with Children on CDC Digital Media Channels
+We will maintain any information you provide in accordance with applicable federal law. CDC will not disclose, give, sell, or transfer any personal information about visitors to our websites, unless required for law enforcement or by statute. Moreover, we do not create individual profiles with the information you provide or give it to any private organizations. CDC does not collect information for commercial marketing.
+Remember, however, that e-mail is not necessarily secure against interception. Therefore, if your communication is sensitive or includes personal information, you may prefer to send it to CDC via postal mail instead.
+We believe in the importance of protecting the privacy of children online. As such, we will take all reasonable steps to protect the privacy and safety of any child from whom information is collected as required by the [Children's Online Privacy Protection Act (COPPA)](http://www.business.ftc.gov/privacy-and-security/childrens-privacy). A child's parent or guardian is required to provide consent before CDC collects, uses, or shares personal information from a child under age 13.
+If you choose to provide us with personally identifiable information (PII) - that is to say, information that is personal in nature and may be used to identify you - as in an e-mail message, questionnaire, form, online survey, or other tool, submitted through our website, we will maintain the information that you provide only as long as needed to respond to your question or to fulfill the stated purpose of the communication. If we store your personal information in a records system designed to retrieve contact information about individuals by personal identifier (e.g., name, personal e-mail address, home (mailing) address, personal or mobile phone number, etc.), we will safeguard your information in accordance with the Privacy Act of 1974, as amended (5 U.S.C. 552a).
+When a CDC Web site needs to collect information about a child under 13 years old, COPPA required information and instructions will be provided by the specific Web page that collects information about the child. The Web page will specify exactly what the information will be used for, who will see it, and how long it will be kept.
+If, in order to accomplish its mission, CDC operates a system of records from which it retrieves information that you submit, there will be a Privacy Act Notice prominently displayed on the public-facing website or form that requests your PII. If applicable, such Notice must state the following five criteria:
+Personal information about children under 13 years of age may be needed to respond to his/her communication to us. Personal information about your child will be destroyed immediately upon completion of its intended purpose. On rare occasions, it may be determined that a communication from a child under 13 years old should be maintained for historical purposes. Should such an occasion occur, CDC will obtain the necessary consent from the child's parent.
+- The purpose for which CDC is collecting your information
+- CDC's legal authorization to collect your information
+- The Routine Uses for which your information will be disclosed outside of CDC
+- Whether providing your information is voluntary or legally mandatory
+- The effects, if any, of nondisclosure of your information should you choose not to provide it.
+Finally, we provide many on-line tools and services in support of CDC's mission. A child under 13 years old may inadvertently provide personal information to one of these services. If this should happen, the information about the child will be deleted immediately upon discovery.
+For further information about CDC privacy policy, please contact the CDC Senior Official for Privacy at [mailto:privacy@cdc.gov](mailto:privacy@cdc.gov), or call 770-488-8660.
+Our digital media channels are not intended to solicit information of any kind from children under age 13. If you believe that we have received information from or about children under age 13, please contact the CDC Privacy Office (see [Contact information](http://www.cdc.gov/other/privacy.html) here).

+This site is maintained by the U.S. Government and is protected by various provisions of Title 18 of the U.S. Code. Violations of Title 18 are subject to criminal prosecution in Federal court.
+All CDC digital media offerings, including the CDC.gov site, are maintained by the U.S. Government and protected by various provisions of Title 18 of the U.S. Code. Violations of Title 18 are subject to criminal prosecution in Federal court.
+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. Unauthorized attempts to upload or change information on this Website are strictly prohibited and may be punishable by law, including the Computer Fraud and Abuse Act of 1986 and the National Information Infrastructure Protection Act of 1996.
+At CDC, reasonable precautions are taken to protect CDC's digital platforms, including information automatically collected by or voluntarily submitted to CDC.gov or an official CDC page on a third-party site. For example, we restrict access to personally identifiable information to employees, contractors, and vendors who require access to this information in order to perform their official duties, and exercise controls to limit what data they can view based on the specific needs of their position. Access to official CDC accounts on third-party sites is limited to the individuals who administer those accounts, and all official CDC accounts are clearly labeled.
+ [Top of Page]()
+Also, commonly used practices and technical controls are utilized to protect the information in our possession or control, along with CDC.gov itself. These practices and controls include, but are not limited to: encrypting the transfer of personal information over the internet via secure sockets protocols such as Transport Layer Security (TLS), Secure Sockets Layer (SSL) etc., using high-strength firewalls and intrusion detection systems (IDS) to safeguard personal information, and maintaining strict technical controls and procedures to ensure the integrity of all data on CDC.gov.
+## Third-Party Websites and Applications
+We periodically review our processes and systems to verify compliance with industry best practices and to ensure the highest level of security for CDC's all digital platforms.
+In addition to CDC's official website on [www.cdc.gov](http://www.cdc.gov/), CDC uses social media and third-party (non-CDC) websites to share information and to engage the public. For example, there may be third-party applications and/or services linked to or embedded on [www.cdc.gov](http://www.cdc.gov/) to improve its functionality. Likewise, applications created by CDC may be embedded on third-party websites as a way to increase public awareness of CDC activities. Our integration of these products is intended to provide a seamless user experience and to enhance users' ability to access information and communicate with CDC.
