We share your travel document data with the Royal Netherlands Marechaussee to make the border passage possible. Schiphol also shares your email address with providers of social media services, so that you can be invited to join the Privium groups on social media. If your email address cannot be reached, your contact details will be disclosed to an external company, to be able to send your invoice by post. Contact details are also disclosed to external parties to be able to send or offer a gift to you in certain cases. If your membership is paid or will be paid by third parties (for instance, if your employer or company has entered into a Privium Corporate Membership), we will disclose your correspondence name, initials and date of birth to those third parties to ensure that invoicing can take place in the correct manner.
