Pfizer may collect information from you by using “cookies”. Cookies are a small file of letters and numbers that we put on our computer if you agree. These cookies can tell us how and when pages in a website are visited and by how many people. With the information we receive through this technology, we hope to improve our sites. Although cookies do not normally contain personally identifiable information, if you have provided us with information about yourself, we may associate your registration information with cookies or other tracking utilities our website places on your computer's hard drive. Associating a cookie with your registration information allows us to offer increased personalization and functionality. Without cookies, this functionality would not be possible.
Your web browser can be set to allow you to control whether you will accept cookies, reject cookies, or to notify you each time a cookie is sent to you. If your browser is set to reject cookies, websites that are cookie-enabled will not recognize you when you return to the website, and some website functionality may be lost. The Help section of your browser will tell you how to prevent your browser from accepting cookies. To find out more about cookies, including how to see what cookies have been set and how to manage or delete them, visit http://www.allaboutcookies.org (link is external).
In addition, we may use other tracking systems like pixel-tags. Pixel tags, sometimes called web beacons, are similar in function to cookies but because of their insignificant size, they are not visible. However, they are used to pass certain information to our servers to personalize our websites and to track your usage across other Pfizer websites. In addition, we may also use pixel tags in our HTML based emails.
