Cookies and Other Web Tracking Techniques And How We Use Them

When you use our sites, Parexel will assign cookie files (“cookies”) to you, which are a small amount of information we send to your web browser. Cookies enable the computers operating our websites to differentiate between visitors and to track the patterns of activities engaged in by different visitors. By tracking such activities, the computers operating our websites can recognize a visitor and customize certain features for that visitor. We may also use aggregated, non-identifiable information regarding persons who visit our site in order to learn more about the use of the site and how we can improve it.

You may be able to modify your browser preferences to accept all cookies, to be notified when a cookie is set, or to reject all cookies. If you choose not to accept cookies, you may not be able to use those functions of the websites that require registration.

We may also collect IP addresses in the normal course of the operation of our website. An IP address is a number assigned to you by your Internet service provider so you can access the Internet. Although we do receive IP addresses, we do not use them to identify you personally. If you give consent, the IP address may be shared with third parties working with or on behalf of Parexel and will not be used by these third parties for secondary purposes without your consent. 

This website uses the following web analytic tools. The tools use cookies to help the web team analyze how users use the site.

Cookie List

A cookie is a small piece of data (text file) that a website – when visited by a user – asks your browser to store on your device in order to remember information about you, such as your language preference or login information. Those cookies are set by us and called first-party cookies. We also use third-party cookies – which are cookies from a domain different than the domain of the website you are visiting – for our advertising and marketing efforts. More specifically, we use cookies and other tracking technologies for the following purposes:

Strictly Necessary Cookies
