This cookie contains a unique randomly-generated value that enables the Platform to distinguish browsers and devices.
It is matched against information – such as advertising interest segments and histories of ads shown in the browser or device – provided by clients or other third parties and stored on the Platform.
This information is used by clients to select advertisements for delivery by the Platform, and to measure the performance of, and attribute payment for, those advertisements.
In addition, we use this cookie to enable clients to use data which does not reveal or use an Internet user’s real-world identity or data they collect outside of the Platform or acquire from other third parties.
This cookie is also sometimes matched to clients’ or other third parties’ cookies so that they can use data they collect outside of the Platform to serve more relevant advertisements to Internet users.
When a user opts out of having the Platform used to select ads based on online behavior, the unique value in uuid2 is deleted and replaced with the non-unique value “-1”. For more information about the Platform opt out, click here.
For more information about information collected and used on the Platform, see our Platform privacy page.

We use this cookie to measure how often people do things like click on or view ads.
Our clients use this cookie to help deliver ads to people who have previously visited their websites, purchased their products or used their apps and to recommend products and services based on that activity.
When you opt out of the use of interest-based advertising on our Platform this cookie is set with a non-unique value (-1) and sellers using our Platform may show you less relevant ads because neither they nor advertisers can use data about your preferences to show you ads.

Persistent. 90 days.
Please note that our uuid2 cookies may be reset on subsequent calls from a browser to our servers, and the expires property will be reset at that time. Cookies are set and reset this way because many different companies use our Platform, and may be setting, reading, and associating data with cookies at various times and in various places. The retention of data associated with cookies is more relevant than the expiration of the cookie itself. Xandr discloses in its public-facing Privacy Statement a data retention maximum of 18 months. However, most data is retained for a much shorter period than 18 months. Moreover, customers of the Xandr Platform exercise control over much of the data associated with this cookie.
