6.  What about other tracking technologies, like web beacons?

Cookies are not the only way to recognize or track visitors to a website. We currently do not use, but in the future may use, other similar technologies from time to time, like web beacons (sometimes called “tracking pixels” or “clear gifs”). These are tiny graphics files that contain a unique identifier that enables us to recognize when someone has visited our Website or opened an email from us. Web beacons allow us, for example, to monitor the traffic patterns of users from one page within a website to another, to deliver or communicate with cookies, to understand whether you have come to the website from an online advertisement displayed on a third-party website, to improve site performance, and to measure the success of email marketing campaigns. In many instances, these technologies are reliant on cookies to function properly, and so declining cookies will impair their functioning.

If you do not want Flash Cookies stored on your computer, you can adjust the settings of your Flash player to block Flash Cookies storage using the tools contained in the Website Storage Settings Panel. You can also control Flash Cookies by going to the Global Storage Settings Panel and following the instructions to, for example, delete existing Flash Cookies (referred to “information” on the Macromedia site), prevent Flash LSOs from being placed on your computer without your being asked, and (for Flash Player 8 and later) block Flash Cookies that are not being delivered by the operator of the page you are on at the time.

Please note that setting the Flash Player to restrict or limit acceptance of Flash Cookies may reduce or impede the functionality of some Flash applications, including, potentially, Flash applications used in connection with our services or online content.

We do not serve cookies on your computer or mobile device for advertising purposes.  However, third parties may serve cookies on your computer or mobile device to serve advertising through our Website. These companies may use information about your visits to this and other websites in order to provide relevant advertisements about goods and services in which you may be interested.
