This Privacy Notice describes what “personal data” (meaning any information relating to an identified or identifiable natural person) we need to collect from you on the website, how we use it and why, as well as your rights in relation to this collection and use. You are under no obligation to provide personal data to us, but should you decide not to, you will be unable to gain complete access to the website and its content.

Information we collect and how we use it

The website collects different types of personal data depending on how you use it.

If you choose to register to use the website, you will need to create an account and user profile on the website. We may collect the following necessary personal data from you to do this: your name; title; e-mail address; password; postcode; and practitioner/physician licence or identification number.

If you decide to register by using the Google, LinkedIn, or Apple Single Sign-on options, we will receive from these platforms a unique identifier, your first name, last name and email address. To finish your registration, you will then be asked for your postcode; and practitioner/physician licence or identification number.

You can find more information on how Google, LinkedIn, or Apple will process your personal data if you decide to use their Single Sign-on options in their relevant privacy policies.

It is in Biogen’s legitimate interest to process your personal data in this way, and we require this information to: (a) verify that you are a neurosciences healthcare professional; (b) create and manage your account; (c) tailor your user experience and provide you with information that matches your specialty and areas of interests; and (d) provide you with local technical and administrative support, where necessary.

If you provide your consent by ticking the relevant tick box on the website during registration or within the account preferences page, Biogen will use your personal data to send you direct marketing communications (including newsletters, therapy information, insights about diseases, clinical trial information, patient education materials, and invitations to attend meetings or congresses or participate in market research surveys). You may unsubscribe from, and withdraw your consent to, receiving such communications at any time and you may also manage your preferences on the website by logging in to your account. This does not, however, affect the lawfulness of the processing before your withdrawal of consent.

Analytics information

Biogen analyses this information automatically, using an algorithm designed to improve the website and to deliver content tailored to its user’s specialty and areas of interests. The website also uses Google Analytics to collect aggregated personal data from you to assess: (a) the number of times the website is visited; (b) the number of accounts that are created; and (c) the amount of times an article is read or a video is viewed. This data collection technology allows us to distinguish you from other users of this website and to enhance this website and your experience when you use it.

(b) Hotjar – We also use Hotjar to analyse users’ behaviour in their usage of the website to improve the user experience.

Online advertising

We also use Facebook Matching and DoubleClick Manager, to manage our online advertising programme. These data collection technologies are provided by our ad management partners and other third parties. We, and our ad management partners, may use the technologies to track the actions of users of the website, to measure statistics of our marketing efforts, and to deliver advertisements on third party websites. We support the Self-Regulatory Principles for Online Behavioral Advertising of the Digital Advertising Alliance. This means that we allow you to exercise choice regarding the collection of information about your online activities over time and across third-party websites for online interest-based advertising purposes. More information about these principles can be found at If you want to “opt out” of receiving online interest-based advertisements, please follow the instructions at or An “opt-out” cookie will be placed on your device indicating that you do not want to receive interest-based advertisements. If you delete cookies on your device generally, you will need to opt-out again. Please note that when you “opt-out” of receiving interest-based advertisements, this does not mean you will no longer see advertisements from us. It means that the online ads that you do see will not be based on your interests.
