Like many common online services, our technology uses cookies to store a unique user-id on your computer/browser when you visit a site that uses our measurement technology. The only information stored in these cookies is your user-id and a session-id. They contain no personally identifiable information.
We use your user-id to count the unique viewers on our customers' and partners' video assets. The user-id can also be used to measure unique visitors to a site hosting ads or other video content. We use the session-id to count viewing sessions. These sessions expire after 30 minutes of no viewing activity.
Our measurement services are powered by common browser cookies. Some of our older APIs still use "Flash cookies," also known as Flash Shared Objects. We are committed to moving away from Flash cookies and will keep you informed on our progress.
