Privacy Statement

This is the Privacy Statement for users of our Select service and our other solutions to align the supply and demand of a contingent workforce. Select is an online hiring platform where independent professionals and suppliers of professionals can meet. Select is provided by HeadFirst B.V. and its affiliated entities. In what follows, we will use HeadFirst, we, our and us to refer to the data controllers in this Privacy Statement.

We process your personal data when you use Select, when you visit one of our websites, including, and when you contact us. For example, you can contact us via email, request information and chat with us via our website. We may also process your personal data when a supplier you work with enters your personal data in Select.

Carefully handling your personal data is important to us and we like to be clear about this to all Select users and other persons whose personal data we process (hereinafter referred to as “Data Subjects”). In this Privacy Statement, we will explain how we handle your personal data.

Who are the controllers?

The controller is the party that determines how and why personal data are processed. The controller determines the purpose of and the means for the data processing. Under the General Data Protection Regulation (GDPR), most obligations rest with the controller and it is also the first point of contact for you as the Data Subject.

HeadFirst has joint data controllers. This means that several parties jointly determine how your personal data are processed. We have designated a principal controller to make sure it is clear to Data Subjects who they can contact if they have queries or complaints. This is HeadFirst B.V., with its registered office at Polarisavenue 33, 2132JH in Hoofddorp. You can reach us by telephone on +31 (0)23 568 56 30 and by email via Other entities from our group that may process your personal data as a controller are the following:

  • Associates B.V.
  • Designated Professionals B.V.
  • HeadFirst Germany GmbH
  • HeadFirst IT B.V.
  • HeadFirst Poland sp. z o.o.
  • Jenrick Nederland B.V.
  • Jenrick Payroll Services B.V.
  • Myler B.V.
  • Oyster Coast B.V.
  • Proud ICT B.V.
  • Proud Payroll B.V.
  • Source Automation B.V.
  • Source Automation BV. (Belgium)
  • Source Automation Luxemburg SA
  • Source Payroll Services B.V.

If you are a professional whose personal data are provided to us by a supplier and you yourself are therefore not using Select, that supplier is classified as an independent controller. In that case, the supplier determines the purpose and the means, and is the first point of contact for you if you want to exercise your rights under the GDPR. The supplier may have its own privacy statement and its own terms and conditions. We advise you to read them.

What personal data do we process?

What personal data we process depends on the services you are using and the capacity in which you are using those services.

In that context, we may process your name, email address, or other contact details. We will also process other personal data insofar as you disclose such data in your query or request or during the chat.

We may process your personal data for the purposes specified in this Privacy Statement under ‘Services’ and ‘Compliance and security’. We have a legitimate interest in this further processing, i.e. to be able to provide our customary services, to comply with agreements with and assignments from suppliers and clients, and to be able to meet the applicable market quality standards. We also have a legitimate interest in ensuring that the supplier who works with us can fulfil its obligations to you and in ensuring that you can be used for the selected assignment. We always weigh up our interests and your privacy interests as a Data Subject. If you want more information on this weighing up of interests, please contact us via the contact details stated under ‘Who are the controllers’ in this Privacy Statement.

If you were signed up by a supplier, you do not have your own account with your own password. The supplier provides your personal data to us and is the controller in that respect. If you want to know more about how the supplier handles your personal data and which of your personal data it discloses to us, we advise you to read the supplier’s privacy statement or to ask the supplier for information. We are neither responsible nor liable for the personal data that the supplier processes. This Privacy Statement solely covers the further processing of personal data by us.

For what purposes do we process personal data?

On what grounds do we process personal data?

We process personal data only if there is a legal basis for doing so.

  • Performance of the agreement.We conclude agreements with professionals, suppliers and clients on the basis of which we process personal data. These agreements relate to the services we provide. It is also conceivable that we request personal data from you before concluding an agreement to enable us to form the agreement.
  • In certain situations, we may ask for your consent prior to the data processing. For example, we ask for your consent before sending you certain news reports. After giving your consent, you may revoke it at any time, following which we will refrain from any further processing of your personal data for the purposes covered by the consent.
  • Legal obligation. In some cases we are required by law to process certain personal data. For example, pursuant to the Foreign Nationals Employment Act (Wet arbeid vreemdelingen) or tax obligations. A legal obligation may also mean that we are required to share certain personal data with clients, supervisory authorities or other third parties for further processing.
  • Legitimate interest. We may process personal data because we have a legitimate interest in doing so, or because the organisation to which we disclose your personal data has a legitimate interest. For example, to prevent tax liability or reduce the risk of such liability, or to prevent and investigate fraud. We also have a legitimate interest in further processing personal data of professionals who are signed up to Select with their consent in order to be able to provide our services and to put the professional on an assignment. We always weigh up our interests and those of the Data Subjects. If you want more information on this please contact us via the contact details stated under ‘Who are the controllers’ in this Privacy Statement.

Pre-employment screening

We carry out pre-employment screening for some assignments. We do so because the client requests it, e.g. because it is required by law (e.g. under the Financial Supervision Act (Wet financieel toezicht)) or because it follows from the nature of the assignment. Where necessary, we will inform you that screening is part of the selection procedure for the assignment you are eligible for and we will explain how we are going to carry out the screening.

If a client indicates that screening is desired or required, we will always check the nature of the assignment, how the screening needs to be carried out and what the client’s legitimate interests are. We will weigh up the client’s interests and your privacy interests. We will only carry out the screening if your privacy interests do not impede it.

If we carry out screening, we will process data about your suitability, reliability and integrity that are relevant to the performance of the assignment. The extent of the screening depends on the assignment. We may, in any event, check the data that you or the supplier completed in Select as part of the screening. Added to that, and depending on the nature of the screening, we may process information about references, former employers/clients, antecedents, data on previous performance, suspension or dismissal, a certificate of good conduct or a certificate of no-objection and a list of ancillary positions.

Depending on the nature of the screening, we disclose your personal data to the client. We may also ask you to fill in a screening form provided by the client. The information completed on the form is only processed for the deployment at the client stated on the form and shared with this client, unless otherwise agreed. It is also conceivable that we carry out screening and only let you know whether you completed the screening with a positive result. In that case, we will not share any other data with the client.


If you are a professional, we may analyse the personal data you have disclosed which relate to your professional background and prepare profiles based on those data. That helps us to ascertain which assignments and which clients would best suit your knowledge and experience. We prepare profiles using the keywords you have filled in and one of our staff members will check the result. Added to that, we may use special software to match the text in your profile and CV with an assignment.

We will not take fully automated decisions (without human intervention) that significantly impact you as a professional on the basis of the profiles prepared by us and the outcomes of the matching software.

Direct marketing

We offer you the option to subscribe to our newsletters and to other direct-marketing communications from us or from other companies within our group. If you have consented to this, we may also send you messages about initiatives taken by our associate partners. You can easily unsubscribe from our communications at any time by using the unsubscribe link in the emails or by updating your preferences in your profile environment.

We use conventional tracking techniques that provide information on the reach and effectiveness of our direct marketing communications. This enables us to improve our service provision and to focus our information and communications on the relevant target groups.


We use cookies and similar technologies on our Websites and in our apps. We find it important for you to know how and why we use cookies because we want to guarantee your privacy and improve the user-friendliness of Select. We recommend that you read the cookie statements on our Websites.

Who can access your personal data?

Our staff members can access your personal data on a need-to-know basis. This also means that people working for the companies affiliated to us can access your personal data to the extent necessary to provide our services.

In certain situations, we may share personal data with third parties. We will do so only if this is necessary to provide our services and if it is in keeping with the purposes described in this Privacy Statement.

  • From within our group, we may share personal data with affiliated entities, whether or not they qualify as joint controllers. We may also share personal data with legal successors (including envisaged legal successors) as well as with potential and new group entities and/or their shareholders if they intend to work with us or continue to provide our services.
  • We may share professionals’ personal data with our clients and with any supplier who has registered the professional in Select. These parties can be classified as independent controllers.
  • We may share personal data with service providers we work with who qualify as independent controllers, such as financial service providers, legal advisers, consultants, auditors and credit and security providers. We may also use services provided by a third party for pre-employment screening. We always decide in advance which personal data need to be disclosed to such parties to enable them to provide their services. If necessary, we make additional arrangements about the division of responsibilities.
  • We use service providers for aspects such as managing Select and for hosting. We also use service providers to check your identity document on our behalf, and we use software solutions for the automated processing of CVs and to match CVs with assignments. Where such service providers process personal data on our behalf as processors, we set out the arrangements in a processing agreement.
  • We only share personal data with supervisory authorities, tax authorities and investigative bodies if and to the extent that we are obliged to do so by law.

Will your personal data be safe?

We have taken appropriate technical and organisational security measures in order to protect the personal data we process against loss or unlawful use. For example, we secure our systems and applications in accordance with the information security standards currently in force. In addition, we have made arrangements with our service providers and obliged them to take adequate security measures.

Will your personal data be processed outside the EEA?

In principle, we process your personal data within the European Economic Area (EEA). We use servers that are in Europe and our group companies are established in the EEA. Because we may use the services of processors who have their main establishment outside the EEA, it cannot be ruled out that we may share personal data with organisations outside the EEA, either directly or indirectly. Where this is the case, we will take appropriate measures to legitimise such processing, including entering into a transfer agreement on the basis of standard contractual clauses (SCCs) approved by the European Commission. If required, we will take additional measures to ensure an adequate level of protection. If you want to know more about the transfer of personal data and how this is legitimised, contact us using the contact details provided in this Privacy Statement.

How long do we retain your personal data for?

We retain personal data only for as long as this is necessary for the purposes described in this Privacy Statement. We have drafted a retention policy in this regard. This includes the following retention periods:

  • We retain personal data of our business customers, including suppliers, clients and professionals, for up to two years after our business relationship with them has ended. This applies inter alia to the profiles in Select.
  • We retain business agreements and any correspondence about them for seven years after the contractual relationship has ended unless there are still disputes or proceedings pending in that regard.
  • We retain personal data relating to the verification of your identity for five years after our business relationship has ended.
  • We retain registration data for the newsletters until you have unsubscribed from them, up to a maximum of two years after our business relationship ends.
  • We retain complaints, correspondence about disputes and reports on incidents for seven years after they have been fully dealt with.
  • We retain documents on payrolling as well as salary records for seven years.
  • We refer you to our Cookie Statements on the Websites for the retention periods that apply to cookies.
