Market research and scientific research

Information about the use of your information for the conduct of market research.


What personal information do we use? 

Depending on the subject of the research, we may use information such as your contact details, travel preferences, and derived travel information, such as how you spend your free time.

What do we use your personal information for? 

We regularly conduct research into the satisfaction of our travellers and visitors to our stations, regarding the stations, the train journey, and other products and services. You may volunteer to participate in these studies.

The principle behind processing the information is: permission.

If you have signed up to participate, we will send you one or more invitations to express your opinion on an NS product or service. This will involve processing your contact details. You can decide on an invitation-by-invitation basis whether you would like to participate or not. If you would no longer like to receive invitations, simply click on the 'cancel participation' link at the bottom of the e-mail. Your details will then be deleted, and you will not receive any more invitations to participate in market research surveys.

We may ask you to participate in a traveller survey during your train journey. Depending on the type of traveller survey, we may ask:

  1. whether we may scan your travel product, such as your OV-chipkaart,
  2. whether we may send an invitation to participate in the customer satisfaction survey to your e-mail address,
  3. whether you would be willing to fill in a survey about your travel experience.

Compatible use: scientific research and statistical purposes.

Finally, we may conduct or commission scientific or other research for statistical purposes. Such research may involve the processing of personal information. In that case, we will implement sufficient safeguards to ensure that the information is only processed for scientific purposes.

With whom do we share this information? 

We contract third parties to provide IT services. These third parties process our information solely for our own internal use, and for no other purpose. We have made agreements with these parties pertaining to the processing of personal information.

We may contract an external marketing bureau to conduct research on our behalf and to collect and/or analyse the data. These third parties process our information solely for our own internal use, and for no other purpose. We have made agreements with these parties pertaining to the processing of personal information.

It is possible that we will share your personal data with scientific organisations such as universities for the purposes of scientific research. In such cases, we will reach agreements with them regarding the processing and protection of your personal data.

We are authorised to provide your personal information to parties outside the European Economic Community under certain circumstances. In that event, we will take suitable measures with these parties, for example by agreeing to the standard provisions required by the European Commission.

How long do we store your information?

We will store your registration and contact details for an unlimited period, until you indicate that you would no longer like to participate in market research surveys.
