The Hague, June 2025
According to the General Data Protection Regulation (GDPR), every processing of personal data must be lawful, including the processing activities carried out by Ad Hoc Data in the context of its services to customers. Such processing must be based on a legal ground as referred to in Article 6(1) of the GDPR. This document specifically focuses on the processing of personal data by Ad Hoc Data in the context of its services, based on legitimate interest within the meaning of Article 6(1)(f) of the GDPR.
The principle is that processing is lawful if it is necessary for the legitimate interests of Ad Hoc Data or a third party, unless the interests, fundamental rights, and freedoms of data subjects override those interests. In this explanation, this legal basis is elaborated according to the three-part test, which requires that (i) a legitimate interest exists, (ii) the processing is necessary, and (iii) the interests are carefully balanced.
This analysis is exclusively concerned with the processing of personal data in the context of Ad Hoc Data’s services, including the recording and making available of personal data in its database. Other processing activities by Ad Hoc Data based on legitimate interest, such as internal processes or marketing activities, are outside the scope of this document. The purpose of this document, in addition to clarifying the balancing of interests conducted by Ad Hoc Data, is also to demonstrate how Ad Hoc Data complies with legal obligations and contributes to a more transparent and fair economic ecosystem.
The personal data processed by Ad Hoc Data have an explicitly business and public character and concern only data relating to enterprises. Part of the data in Ad Hoc Data’s database qualifies as personal data. The processing of personal data by Ad Hoc Data is carried out within a careful legal framework and with extensive safeguards, including transparency and clear contractual arrangements with customers.
Disclaimer regarding this English translation This document is an English translation of the Legitimate Interest Assessment originally drafted in Dutch. This translation has been provided for the convenience of data subjects. In case of any discrepancies or differences in interpretation, only the Dutch version of the Legitimate Interest Assessment is legally binding and rights may only be derived from the Dutch version.
The first step in the three-part test concerns the analysis of the legitimate interests involved in the processing activity (or activities). There must be a current interest in the processing by Ad Hoc Data in order to make this available to its customers. The interest(s) must also be legitimate.
Ad Hoc Data, in the context of its services, processes in its database only personal data that are related to enterprises. Removing personal data from the Ad Hoc Data database would have several negative effects on both business operations and its role in commercial transactions. The relevance and usability of the database would be significantly reduced, as essential personal data, including the names of legal representatives and part of the contact information, would be missing. As a result, Ad Hoc Data’s commercial opportunities would come under significant pressure, especially in comparison to competitors who do provide such data, as its core activity—delivering up-to-date and reliable business information—could no longer be carried out in a comparable manner. The socially relevant role that Ad Hoc Data plays in commercial transactions, contributing to economic transparency and fair competition by making current and relevant data available at an accessible rate, would also be greatly restricted, as the database without personal data would contribute less effectively to a level playing field for enterprises.
It is relevant to note that, according to the case law of the Court of Justice of the European Union, it has been determined repeatedly that a purely commercial interest can also constitute a legitimate interest. Case law of the European Court of Justice1 supports the lawfulness of processing by Ad Hoc Data.
The legitimate interest of Ad Hoc Data
Ad Hoc Data has a direct, own interest in processing personal data relating to enterprises. This interest lies in its core activity: providing customers with up-to-date, reliable, and structured business data about enterprises. By processing this data, Ad Hoc Data can, among other things:
The Legitimate Interest of Ad Hoc Data’s Customers and Third Parties
In addition to Ad Hoc Data’s own interest, the interests of its customers (including potential customers) are also served by Ad Hoc Data’s processing activities. Customers are supported in, among other things:
The processing of personal data by Ad Hoc Data takes place on the basis of a legitimate interest, where both commercial and functional considerations play a role. For Ad Hoc Data, this interest lies in conducting its business by providing customers with accurate and up-to-date business information in support of their business activities. The processing of personal data relating to enterprises is in line with legal frameworks regarding the use of enterprise data, including Article 2 of the Dutch Trade Register Act. In addition, case law1 shows that commercial interests, under certain conditions, can be considered a legitimate interest, provided that the processing is proportionate and within the reasonable expectations of data subjects.
The processing of personal data must be necessary for the realization of the legitimate interests. It must be assessed whether these interests cannot reasonably and equally effectively be achieved by other means that are less detrimental to the rights of the data subject, including the application of measures to minimize the impact on data subjects.
Essence of the Processing
Ad Hoc Data focuses on processing data of enterprises, including personal data, which are essential for the provision of its services. The processing of this data is a crucial part of Ad Hoc Data’s core activities and services.
Limitation to Business Purposes
The processing by Ad Hoc Data is strictly aimed at business purposes and is limited to personal data that are essential for the professional activities of enterprises. As a result, the impact on the private lives of data subjects is minimized.
Assessment of Less Intrusive Alternatives
In accordance with the GDPR, Ad Hoc Data has thoroughly examined whether less intrusive alternatives are possible. The conclusions are as follows:
In all of the above cases, if Ad Hoc Data does not process these data, there is a risk that (potential) customers will obtain comparable or even more extensive personal data via data brokers in countries with less strict privacy legislation. This enables such providers to offer more attractive and relevant services, thereby forming a more appealing alternative for customers. This increases the likelihood of a shift in the market toward such parties, which leads to greater risks for data subjects due to less transparent, less controllable, or even potentially unlawful processing of personal data. This not only entails additional risks for the data subjects themselves but also for the users of such services. Ultimately, this could mean that the data offered by Ad Hoc Data becomes less relevant and attractive for its (potential) customers, with a significant impact on the market and competitive position of Ad Hoc Data as a result.
Data Minimization
Ad Hoc Data has taken extensive measures to limit the processing of personal data as much as possible and processes only data that are necessary for its business services, including:
The processing is necessary to achieve the intended purposes. Alternatives, such as the use of fully anonymized data or only data that do not qualify as personal data in themselves, have been examined but have proven insufficiently effective to achieve the same results to an equivalent extent given the purposes and legitimate interests.
In the balancing test, a weighing of interests is conducted between the legitimate interests for processing by Ad Hoc Data and any infringement by the (intended) processing on the interests, fundamental rights, and freedoms of data subjects, taking into account the specific circumstances of the case, in particular the reasonable expectations of the data subject as well as the scope of the processing and its consequences for those data subjects.
Business and Public Nature of the Data:
The personal data processed by Ad Hoc Data have a distinctly business and public character. Because the processing concerns personal data with a business and public character, the infringement on the rights of data subjects is minimized. These data, such as the names and functions of directors or representatives of enterprises, are generally already publicly available through sources such as business registers (including the Trade Register). The processing of personal data from public sources constitutes a less significant and less frequent infringement on the privacy of data subjects. Precisely because these personal data are already publicly available via such sources, there is a lesser impact on the private lives of data subjects.
Nature of the Data:
Ad Hoc Data processes only personal data that are relevant in a business context, such as names and business contact details (of representatives) of enterprises. No special or sensitive personal data are processed, such as data concerning religion, health, criminal records, data of minors, or personal data that by their nature would be regarded as particularly sensitive. By focusing on non-sensitive, business data, the impact on the privacy of data subjects remains limited.
Source of the Data:
The personal data processed by Ad Hoc Data originate from reliable, recognized data provider(s). These provider(s) ensure that the data have been lawfully obtained and are suitable for the intended business purposes of Ad Hoc Data. By collaborating with parties who meet all legal requirements, Ad Hoc Data guarantees the lawfulness and quality of the personal data it processes.
Currency of the Data:
Ad Hoc Data ensures (among other things) the currency of its database by erasing all data on a monthly basis and replacing them with current information. This approach prevents obsolescence within the database and ensures that the processing of personal data is limited to up-to-date data. In addition, Ad Hoc Data conducts internal quality controls to ensure that the processed data at least meet market-standard levels of accuracy and consistency.
Reasonable Expectations of Data Subjects:
Data subjects can reasonably expect that their personal data will be processed in a professional context for purposes such as those of Ad Hoc Data, given the nature and purpose of these data. The information processed by Ad Hoc Data, such as names and contact details (of representatives) of enterprises, is deliberately made public in order to enable participation in commercial transactions and to support business interactions. This business and public nature of the personal data reinforces the expectation that these will be used for business purposes, as is also the case with processing by Ad Hoc Data.
Legal Obligations and Publicity:
Enterprises are required by the Trade Register Act to make certain (personal) data public by registering in legally designated registers. Such data include, among others, business addresses, contact information, and names of representatives. This obligation serves, among other things, to increase transparency and legal certainty in economic transactions and to promote the economic interests of commerce, industry, trade, and services.
Freedom of Choice for Entrepreneurs:
Entrepreneurs make a conscious, voluntary decision to start a business and thus deliberately participate in economic activity. Likewise, the business address of their enterprise and the contact details (including any personal data) that they wish to use for registration in the legally prescribed registers are a free choice of the entrepreneurs. These data are provided with the aim of increasing transparency and legal certainty in economic transactions and to promote the economic interests of commerce, industry, trade, and services. Ad Hoc Data aligns with these voluntary choices by only processing data that entrepreneurs have deliberately disclosed and intended for commercial use, and furthermore, Ad Hoc Data itself chooses not to include certain contact details in its database. This processing respects the freedom of entrepreneurs to participate in economic activity under circumstances they themselves have determined, while at the same time contributing to a transparent and accessible market, taking into account the GDPR.
Impact on Data Subjects and Safeguards:
The impact of Ad Hoc Data’s processing on the privacy of data subjects is limited, as only business and publicly available personal data are processed. The nature of these personal data corresponds with professional purposes and does not include sensitive or special categories of personal data. To further protect the rights of data subjects, Ad Hoc Data has implemented extensive safeguards. For example, Ad Hoc Data responds very favorably to requests for deletion of personal data and regularly goes beyond what is legally required by also removing non-personal data if deemed desirable.
Transparency:
Ad Hoc Data publishes both its Privacy Statement and this comprehensive explanation of the Legitimate Interest Assessment (LIA) on its website. The Privacy Statement informs data subjects about which personal data are processed, for what purposes, and what rights they have under the GDPR. This LIA provides a detailed explanation of the balancing of interests made in this context regarding the processing of personal data in the Ad Hoc Data database on the basis of legitimate interest. These documents have been made accessible to provide insight into how Ad Hoc Data structures its processing and to ensure transparency.
The interests of Ad Hoc Data, its (potential) clients, and the broader economic interest, the interest of legal certainty in commercial transactions, and competition outweigh the limited infringement on the personal privacy of the data subjects. The processing takes place within a professional context and concerns only publicly available, business-related data connected to enterprises, and corresponds to the reasonable expectations of data subjects. In addition, various safeguards are in place to ensure compliance with applicable privacy legislation, such as transparency, data minimization, and organizational and technical security measures. In doing so, Ad Hoc Data goes further than most other comparable market participants in protecting the interests of data subjects.
The processing of personal data in its database for the purpose of providing services to its clients by Ad Hoc Data is an essential part of its business operations and its mission to promote economic transparency, fair competition, and strategic business decision-making. This processing, based on Article 6(1)(f) of the GDPR, meets legal requirements and is carried out within the legal framework.
By focusing on business data with a public and professional character, Ad Hoc Data minimizes the impact on the rights and freedoms of data subjects. The personal data processed, such as names, functions, and contact information of legal representatives, are indispensable for its services and contribute to the objectives of both Ad Hoc Data and its (potential) clients. Furthermore, the processing supports broader societal legitimate interests (including those of third parties), such as safeguarding economic stability, access to business information, legal certainty in commercial transactions, promoting competition, and access to such information, which are essential for entrepreneurship.
Ad Hoc Data has fulfilled the three elements of the tripartite test. The processing of personal data by Ad Hoc Data is therefore, given the elaboration in the above three steps, necessary for the protection of the legitimate interests of Ad Hoc Data, its (potential) clients, and third parties. The interests, fundamental rights, and freedoms of the data subject(s) that require protection of their personal data do not outweigh these interests in the given circumstances, leading to the conclusion that a legitimate interest exists for the processing of personal data by Ad Hoc Data.
1) 1) The KNLTB judgment (C-621/22) confirms that commercial interests can be regarded as legitimate, provided that the processing is proportionate and takes into account the reasonable expectations of data subjects. Furthermore, the Meta Platforms Ireland judgment (C-252/21) indicates that processing within a professional context, provided it meets legal requirements and is transparent, can fall within the boundaries of legitimate interest.
