How Your Information Is Used Our Use of Web Analytic Tools
The ODNI uses a third-party analytics provider (currently Google Analytics) to analyze data from cookies. The third-party analytics provider does not receive PII through these cookies and is prohibited from combining, matching or cross-referencing DNI.gov information with any other information. We have also limited the provider’s ability to see your full IP address (a process known as “IP masking”). Please review Google Analytics’ privacy policy for additional information.
ODNI websites use multi-session cookies to differentiate between new and returning users. These cookies also gather aggregated statistical data and measurements on website usage that ODNI uses to improve website functionality. These cookies do not collect PII about you and are not persistent (i.e., ODNI does not use these cookies to track your use of the Internet. If you do not wish to have these cookies placed on your computer, you can adjust your Web browser’s settings. Instructions for disabling or opting out of cookies in the most popular browsers can be found at usa.gov.
We may use data that your site visit automatically generates for statistical analyses to assess, for example, what information is of interest to users, what technical design elements users prefer, and how users rate system performance. This allows us to make general improvements to our sites as well as to offer tailored content to DNI 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).
In some instances, third party platforms, such as Facebook, Tumblr or Twitter, offer their own embedded analytics that provide users with aggregate information that ODNI uses in the same limited manner described above. These services generally do not provide, nor do we seek, IP related information. Rather these analytic tools commonly available to all users of a given platform allow ODNI to assess engagement with specific content and to evaluate engagement trends over time.
