Cookies are small text files that are placed on your computer or other web-accessing device by this website that allow us to recognize you and maintain your preferences when you return to our website. Cookie technology collects “clickstream” data, which does not include direct personal identifiers, but which reflects your activities on the website and helps us to customize our website experience and anticipate what may be of interest to our users, by monitoring traffic in popular areas and modifying the services and information to meet customer demand.

We use the following types of cookies:

  • First-party cookies – cookies set by the website displayed in the browser window – identified by the domain name in the address bar of the browser window.
  • Session cookies – cookies that expire at the end of a browser session, starting with the time when a user opens the browser window, and finishing when the user exits the browser.
  • Persistent cookies – cookies that ‘persist’ (are stored) in the device after the end of a browser session and therefore can allow the preferences or actions of the user to be remembered when they return to the website.

Internet tags

Occasionally, we may use Internet tags (also known as web beacons, action tags, single-pixel GIFs, clear GIFs, invisible GIFs and 1-by-1 GIFs) on this website. We may deploy these tags and cookies through a web analytical service partner, which may locate and store the respective information, including your IP address, in a foreign country that may protect the protection of personal data differently than the country where such information is collected. These tags are placed on different pages of this website and we use this technology to measure the registered user’s responses to our websites, including how many times a page is opened and which information is consulted, as well as to measure the use of this page.

Google Analytics

This website uses Google Analytics, a web analytics service provided by Google, Inc. ("Google"). Google Analytics uses cookies. The information generated by the cookie about your use of this website is generally transferred to a Google server in the United States and stored there. Because we have activated “internet protocol anonymization” on this website, Google shortens your IP address at a point within the European Economic Area before transfer to the United States. This means that the full IP address will be transferred to Google in the United States only in exceptional circumstances for shortening there. Google will use the received information to evaluate your use of this website for Biogen, to compile reports on website activity, and to provide other services related to website usage and internet usage. The IP address provided by your browser as part of Google Analytics will not be merged with any other Google data.
