  • Place of residence

The data listed above will not be stored by Medians. Only the reference of the trial and the timestamp (date and time) are stored in our Medians database. This data is important to us because we can gain (statistical) insight into the number and diversity of the registrations.

Subscriptions for the Medians newsletter

If one indicated one wants to follow Medians news and subscribes to the newsletter (directly through the newsletter subscription form or via through the trial application form) we save, after the user has (re)confirmed this by clicking a confirmation link (double opt-in), the following user data:

  • Email address 
  • First name
  • Last name
  • Date of birth

Mailchimp’s servers are located in the United States, and the company therefore has to comply with the Privacy Shield: regulations that American companies need to adhere to in order to bring the treatment of personal data in line with European regulations.
