VI. Third-Party Advertising and Targeted Advertising

You may be provided with online advertisements of our products and services on third-party websites and mobile services that are tailored to you, for example, on the basis of information that you provide to us or a third-party website you are visiting, or of your browsing activity, purchases or interests. These types of tailored online advertisements may come through several sources, such as the following:

  • We may share with our advertising service providers your non-identifying information that we have obtained from cookies and other tracking technologies on the Regeneron Sites.
  • Some sites participate in online targeted advertising (this is also sometimes called re-target advertising or interest-based advertising). You can identify these sites by the “Advertising Choices” link in the footer. Our advertising network partners may place and use cookies on our websites and on other third-party websites to collect information about your activities in order to provide you with online advertisements that are based on your interests. When an online targeted advertisement is delivered to you, you will see an “Ad Choices” icon. Clicking on the icon or link will take you to a website where you can manage or opt out of the use of data about your browsing history that is used for the delivery of online behavioral advertisements. If you opt out, you may still see advertisements online, including advertisements from us that are based on other information (e.g., based on the content of the page being viewed rather than your prior clickstream activity). In some cases, data may still be collected about your browsing activity by these third-party advertisers, but they will not use this data to deliver advertisements that are based on your past online browsing behavior. You can also opt out now by visiting youronlinechoices.
  • Some web browsers may transmit “do-not-track” signals to websites with which the browser communicates. As of the effective date of this Privacy Policy, an industry standard has not yet been established on how to respond to these signals. Therefore, Regeneron does not currently respond to these signals. As discussed above, you can opt out from advertisers that use your browsing history to deliver online targeted advertisements by visiting youradchoices.

VII. Social Media

Regeneron is not responsible for the information collection, use, disclosure or security policies or practices of other organizations such as Facebook, Apple, Google, Microsoft, RIM or any other social media platform provider, operating system provider, wireless service provider or device manufacturer, including with respect to any personal data you disclose to other organizations through or in connection with our Social Media Pages.

Regeneron may provide the option for individuals to participate in polling activities. Additionally, Regeneron may monitor social media channels for mentions of our brand, competitors, and products, which gives Regeneron an opportunity to track, analyze and respond to conversations about us on social media.

VIII. How Long Do We Retain Your Information?

We retain your personal data for the period necessary to fulfill the legitimate business purposes or uses outlined in this Notice, unless a longer retention period is required or allowed by applicable data protection law or to otherwise fulfill a legal obligation. We generally do not retain the information collected on the Regeneron Sites for longer than five years unless we have a need to retain it.

What are cookies?

Cookies are small text files that are stored on the browser of your computer. They store certain information (e.g., site settings) which your browser may (depending on the lifespan of the cookie) retransmit to us upon your next visit to our Website. 

Most browsers automatically accept cookies by default, but you can adjust the preferences in the browser of your computer or device to warn you each time a cookie is being sent, or to block some or all cookies. While you may still use the Regeneron Sites if you reject cookies, your ability to use some areas of the Regeneron Sites may be limited.

A cookie can temporarily store anonymous information about the use and users of a website.

Website Analytics

Regeneron Sites use Google Analytics, a web analysis service of Google Inc. 1600 Amphitheatre Parkway, Mountain View, CA 94043, United States (“Google”).

Google will analyze your use of our Website on our behalf. The information collected by Google in connection with your use of our Website (including your IP address) will be transmitted to a server of Google in the US, where it will be stored and analyzed. The respective results will then be made available to us in anonymized form. Your usage data will not be connected to your full IP address during this process. We have activated on our Website the IP anonymizing function offered by Google, which will delete the last 8 bits (type IPv4) or the last 80 bits (type IPv6) of your IP address.

Google will use this information for the purpose of evaluating your use of the website, compiling reports on website activity for website operators and providing other services relating to website activity and internet usage.

You can opt out of the use of web analysis at any time, either by downloading and installing the  Google Browser Pluginor through the Privacy Preference Center link in the footer.

Both options will prevent the application of web analysis only as long as you use the browser on which you installed the plugin.
