Privacy policy

This Privacy Policy (the “Policy”) describes practices of Biogen Inc., its subsidiaries, affiliates, and agents (collectively, “Biogen”, “we”, “our”, or “us”) in connection with information we collect, use, and disclose through a cognitive health study called “Intuition” (or the “Study”) presented by Biogen, in collaboration with Apple Inc. (“Apple”), featuring a mobile application (the “Study App”) used with the Apple Watch and iPhone and a Study website,, (the “Study Website”).

The Study combines sensor, health, and usage data to allow participants to complete certain thinking and memory activities, respond to surveys, and receive notifications about cognitive health activities. This Study is available to residents of the United States who meet certain criteria for participation and have agreed to the “Informed Consent Form” (or “ICF”) for the Study. This Policy describes the collection, use, and/or disclosure of all data and/or information collected or accessed by the Study (called “Intuition Data”). Intuition Data includes “Study Data” as defined in the ICF. Participants will be emailed a copy of their signed ICF and can also view an unsigned copy of the ICF in the Study App.

By participating in the Study and/or otherwise providing us with your information, you consent to our collection, use, and disclosure (including transfer) of your information in accordance with this Policy. Please do not provide us with any information if you do not accept this Policy.

What types of information do we collect?

We may collect two types of information when you participate in the Study or otherwise access Study-related materials, including through the Study App and Study Website: Personal Information and Non-Personal Information. When this Policy uses the term “Intuition Data”, this includes both Personal Information and Non-Personal Information.

By “Personal Information,” we mean data that is associated with an identifiable individual, such as a name, physical address, phone number, or email address. Personal Information includes, for example, personally identifiable demographic information, mental health or medical information, behavioral or lifestyle survey responses, or medical history information, including information collected through the Study App on your Apple Watch or iPhone and other Study-related activities.

By “Non-Personal Information,” we mean information that is not associated with an identifiable individual. Non-Personal Information may include information which would otherwise be Personal Information, but which has been de-identified or aggregated.

How do we acquire and use your information?

We acquire Intuition Data through your participation in the Study and when you access or seek out Study information, including through the Study App and Study Website.

After you consent to participate in the Study, certain Intuition Data is collected through the Study App including your contact and demographic information, your health and activity information from the Apple Health app, as well as other Study activity information. For example, we collect information about how and when you use the Study App to help us better understand user behavior. The ICF describes the full listing of the categories of Intuition Data that may be collected, used, and/or disclosed as part of your participation in the Study, including information collected through the Study App, as part of enrollment identity verification, survey responses, and other information from virtual visits.

Your Intuition Data will never be sold or used to drive sale of any products. It may be used in accordance with the Terms of Use which may include using the information you share in support of the Study, to adjudicate rewards, to identify and deliver messages that may be helpful to your cognitive health and wellness or otherwise of interest to you.

When you access the Study Website, we may use "cookies" and other technologies such as pixel tags and web beacons. These technologies are used to monitor website activity such as the number of users, their frequency of use, and which parts of the website they have visited. When you visit the Study Website, our servers automatically log your internet protocol (IP) address. The IP address is a unique number assigned to your computer to identify it whenever you are surfing the Web. The IP address is not used to identify or track you personally but is used to maintain communications with you as you move about the Website. While these technologies can tell us when you use the Study Website and which pages you visit, it cannot read data off your hard disk or mobile device. You can set your cookies when you first enter the Study Website by choosing your cookie preferences in the box that appears in front of the webpage. A link is provided at the bottom of the Study Website’s homepage that you can click anytime to bring up the cookie settings box to confirm or change your preferences.

We may collect, use, and disclose your Intuition Data, which includes your Personal Information, for the purposes listed below and, if you choose to participate in the Study, as otherwise described in the ICF:

  • providing you and other users with the services and functions of the Study, including setting up the Study App, informing you about Study or service updates, and managing and redeeming the points you accumulate for completion of Study activities;
  • to identify and deliver Study-related messages that may be of interest to you;
