It might be required that you share some of your data with third parties to use specific services. In such cases Well will ask for your explicit consent to share it, such that you can always decide what should happen to your data. 

When you register in Well, you are asked for consent to duplicate your registration data to Zur Rose (this is to ensure that you are able to receive e-prescriptions and medical documents and is therefore a prerequisite in order to have a registered user profile with Well).
