These clear GIFs allow Us to measure the usage of Our Website by Our visitors and the effectiveness of certain communications and marketing campaigns. We may also use clear GIFs in a similar manner in Our own emails and on Our Website. <br> <br> Clear GIFs can "work with" existing cookies on a computer if they are both from the same website or advertising company. That means, for example, that if a person visited "www.companyX.com", which uses an advertising company's clear GIF, the Website would match the clear GIFs identifier and the advertising company's cookie ID number, to show the past online behavior for that computer. <br> <br> This collected information can be shared with the advertising company. We may provide such information to our Service Providers but that information can only be used by our Service Providers for Our benefit. </p> 3.
