We would like to inform you about the processing of your personal data

KWF Dutch Cancer Society and Pink Ribbon have joined forces. The organizational management of both organizations has been combined. Your personal data is processed by KWF. You can read how KWF processes your data below.

KWF depends on your help to achieve our goals: less cancer, more cure, and a better quality of life for cancer patients. Whether you do this by making a donation, working as a volunteer, sharing a campaign or signing a petition (online or otherwise): all help is very welcome and vital if we want to achieve our mission. In order to create mutual trust between you and KWF, we want to inform you in a transparent manner about the way in which we process your personal details.

We are responsible for your personal data

KWF Dutch Cancer Society is responsible for processing your personal data and thinks it is very important that this data is dealt with prudently. Among other things, this means that we treat your personal data in confidence, that we have taken security measures to protect your personal data against loss, unauthorized access or theft and that we will delete data if we no longer need it for our activities.

When do we receive your personal data?

In order to fund cancer research, we depend on our donors and volunteers. When they register with us, we receive personal data. When you make a donation to KWF Dutch Cancer Society, for instance, your name, address and account number are processed. This information is required in order to register and process your donation. If you are a KWF collector, you signed a petition, you created your own fundraising event for KWF or if you commit yourself to KWF in another way, we will also collect your data for our records.

We may also process your personal data when you use our services. This takes place when you contact our Public Service Desk by email or telephone, for example, when you subscribe to our newsletter. In those cases, we will process data such as your telephone number, your email address, or your name.

Our Privacy Statement relates to KWF and all websites managed by us

Our Privacy Statement applies to the use of personal data by KWF Dutch Cancer Society and by websites managed by KWF. This Privacy Statement relates to those of our websites listed at:

We use your personal data in order to achieve our mission

We use your personal data because we need them to process donations. We can also use your data to help us optimise our service provision and to spread our message further. Sometimes we also keep data because this is required by financial and fiscal obligations (including statutory obligations).

We only process the personal data that is required for the processing of donations or that helps us achieve our mission. Specifically, we process your personal data, so that we can:

  • process and manage your donation
  • keep records with regard to your efforts as a collector or volunteer
  • inform you about new campaigns and can ask you to make a new donation
  • provide you with details relevant to your voluntary work
  • keep a record of who we may and may not approach for our campaigns
  • manage our accounts and fulfil all financial and fiscal obligations (including statutory obligations)
  • test and improve the quality of our service provision, such as gaining an insight into the performance of the Public Service Desk and our website (or websites)
  • carry out market research, enabling us to gear our services more effectively to the needs of our clients
  • update web statistics and make it possible to share them via social media
  • recruit new collectors and volunteers
  • record details of who has signed a petition
  • process any disputes
  • carry out internal and external audits of our services

To inform you about new campaigns and to send donation requests, KWF Dutch Cancer Society also uses the e-mail address of our contributors to reach out to them through social media, e.g. Facebook. We only do this when you have given us permission to use your e-mail address. If you don’t want us to use your e-mail address, you can unregister with us at any time.


KWF Dutch Cancer Society strives to inform (potential) donors in the most appropriate and relevant way. To offer the most accurate personalized information, we use lifestyle and socio-demographic data on a household level (e.g. estimated data regarding age or family composition) from EDM, a reliable external source. More information about EDM can be found on their website We also use public sources such as Statistics Netherlands (CBS).

Combining these sources with our own database, such as data you provided by filling out one of our forms, donations and clicks in our e-mails, we gain insights into your interests and preferences. This allows us to provide relevant information and also reduce marketing costs. In some cases, we use desk research. This means that we collect publicly available information such as known presidencies, prosperity figures, public messages on LinkedIn or newspaper articles. If you wish to object to this approach, please contact us via [email protected].

We do not use your data for any purposes other than those listed above

KWF Dutch Cancer Society does not sell your personal data to third parties. We do, at times, share personal data within joint ventures, when this is required for the purposes of our mission. In addition, we make use of our suppliers’ IT systems in certain cases. On these occasions, the supplier in question may also have access to the system on which your personal data is processed.

In all cases, we ensure these third parties comply with appropriate safeguards in the areas of privacy and security.

We do not retain your personal data for any longer than is necessary

Your personal data is not retained for any longer than is necessary. Our aim is to destroy the personal data of donors once they are no longer needed to help us achieve our goals. Some data is retained because financial and/or fiscal obligations require it. In such cases, your data will be retained for seven years. When this period has elapsed, we will ensure your personal data is deleted prudently.

You have various rights when it concerns your personal data

  1. You are entitled to make a request to inspect your personal data, or to have them corrected or deleted.

  2. You have a right to object. This means you can object to DCS using your data for charitable purposes. This would include the use of your data for our campaigns or for some other purpose, on account of particular personal circumstances on your part.

You can always submit a complaint about the use of personal data by KWF Dutch Cancer Society in general, either to KWF itself or to the Dutch Data Protection Authority.

If you wish to make a request, we will first assess the matter to see if we can process your request. We cannot process your request if we are unable to confirm your identity or if you have recently made a similar request (less than six months ago).

Once we have started to process the request, there are a number of situations in which we have to reject the request. For instance, we have to reject requests in cases when the protection of third-party rights carries more weight. This could be the case if your inspection request also involves the personal data of third parties. If we deny a request, we will provide a written explanation of our reasons for doing so.

You may not agree with our decision about a request concerning inspection, correction, deletion or objection. In that case, you can also lodge a complaint with the Dutch Data Protection Authority:

You can unsubscribe from campaigns and newsletters

If you have made a donation, we may use your address, email address or telephone number to notify you about our new campaigns. This can be done by post, email or telephone. In every email and following every telephone call, we give you the option of unsubscribing from this form of communication. You can also send an email to [email protected] in order to unsubscribe.

Our websites contain links to third-party websites

Our website contains several links to third-party websites. We recommend that you read the Privacy Statement of any website you visit through our site. We are not responsible for the way in which these third-party websites process your personal data.
