Apps from NS & NS International

Information about the use of your data when you use one of the apps provided by NS: NS-app, NS International app and NS Lab-app


What personal data do we use?

When you use any of our apps, the data we use will in any case include your device's screen resolution and operating system, your IP address, your station search history and keys for identifying the device. In addition, you can also choose to enable location data, any discounts entered various notifications and push messages and your device's camera.

You can link our apps to your Mijn NS, Mijn NS Zakelijk and/or Mijn NS International account. If you do so, we will use your contact details, travel history, ticket details, e-ticket, accompanying transaction details and travel balance in the app.

You can link the NS-app and  NS Lab App to your OV-chipkaart. In that case your most recent check in/check out will be used to guide you on your journey.

If you have an NS-Business Card from NS Zakelijk, we will use your business contact details if possible.

What do we use your personal data for?

The basis for processing information is: permission.

If you give us permission to use your personal data, we will use your information in the NS app, the NS Lab app, and the NS International app. With these apps, we can provide you with travel information, send push notifications about delays and changes to your planned journey, put you in contact with NS Customer Services or the Expertise Centre, send NS International online tickets and provide station information.

You can also use the app to view your travel balance and travel history or provide feedback to NS. In the NS app, you can grant permission to share your location along with the feedback provided, and you can grant permission to share your check-in/check-out data when the app is active on your telephone. In that case, we will send you a push notification with an invitation to provide feedback at a suitable moment during or after your journey.

You can also give the application access to your smartphone's camera and photo gallery. The use of the camera can only be offered for the functionality 'Automatically scan your OV-chipkaart', when you would like to upload an avatar to Mijn NS, and/or add a photo of your favourite location. Photos are only stored in the app, and will only be used for that application, with the exception of the photos uploaded to the Mijn NS environment. When the app automatically scans your OV-chipkaart, we will only detect the text on the card, and will not store photos in the app or upload them to the server.

We use the NS Lab-app to test new functionalities that we would like to add to the other apps. You can disconnect Mijn NS, Mijn NS Zakelijk or Mijn NS International from the app or delete your OV-chipkaart data from the app at any time. If you do this, you also withdraw permission for the app in question to use your data.

The basis for processing information is: justified interest.

The NS apps use a variety of tracking SDK’s (software development kits), such as Google Analytics, Firebase and Firebase Crashlytics. An SDK is part of the app's source code, and is used to analyse the use of the app. We analyse the duration of the visits to the app, the frequency of use, the order of pages visited, OS versions, language settings and time zone information in order to optimise the apps and analyse any problems that may occur. We can then use the information collected to make our apps even more user-friendly. To collect this information, the apps uses Google Analytics SDK, Google Analytics Firebase SDK and Firebase Crashlytics. We also use IP-adres anonimisation to make it impossible to trace the data collected to individual users.

With whom do we share this data?

We contract third parties to provide IT and marketing 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 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 data?

If you no longer wish to use an NS app, you can remove the app from your account, delete your account, or delete the app and all data saved. In that case, we will no longer use your data for the app. We will store your IP address for 24 hours in order to be able to block attacks and large numbers of requests from a specific IP address. We use 'server-side logging' to allow the apps to function properly and to track defects. That means we will log the activity on the servers and store the logs for 30 days. No personal information, such as the purchase of an e-ticket, will be included in the logs.

The configuration settings for the app, such as the OS type and the language settings, are stored on your own device in order to ensure a consistent user experience. The apps' configuration settings are stored locally on the device until the app is deleted. Any push notifications sent via the NS app or NS Lab app are stored for 30 days in order to enable the apps to function properly and to trace any defects, after which they will be deleted automatically.

The NS app feedback function will delete your data and preferences automatically six months after the last feedback is sent. We will store your feedback for six months for the monthly reports sent to the Ministry of Infrastructure regarding the realisation of performance indicators. After that, the feedback will be made anonymous unless you choose to have your data deleted earlier.
