WP260 rev.01 – Adopted on 29 November 2017 – As last Revised and Adopted on 11 April 2018

Introduction

1. These guidelines provide practical guidance and interpretative assistance from the Article 29 Working Party (WP29) on the new obligation of transparency concerning the processing of personal data under the General Data Protection Regulation (the “GDPR”). Transparency is an overarching obligation under the GDPR applying to three central areas: (1) the provision of information to data subjects related to fair processing; (2) how data controllers communicate with data subjects in relation to their rights under the GDPR; and (3) how data controllers facilitate the exercise by data subjects of their rights. Insofar as compliance with transparency is required in relation to data processing under Directive (EU) 2016/680, these guidelines also apply to the interpretation of that principle. These guidelines are, like all WP29 guidelines, intended to be generally applicable and relevant to controllers irrespective of the sectoral, industry or regulatory specifications particular to any given data controller. As such, these guidelines cannot address the nuances and many variables which may arise in the context of the transparency obligations of a specific sector, industry or regulated area. However, these guidelines are intended to enable controllers to understand, at a high level, WP29’s interpretation of what the transparency obligations entail in practice and to indicate the approach which WP29 considers controllers should take to being transparent while embedding fairness and accountability into their transparency measures.
2. Transparency is a long established feature of the law of the EU. It is about engendering trust in the processes which affect the citizen by enabling them to understand, and if necessary, challenge those processes. It is also an expression of the principle of fairness in relation to the processing of personal data expressed in Article 8 of the Charter of Fundamental Rights of the European Union. Under the GDPR (Article 5(1)(a)), in addition to the requirements that data must be processed lawfully and fairly, transparency is now included as a fundamental aspect of these principles. Transparency is intrinsically linked to fairness and the new principle of accountability under the GDPR. It also follows from Article 5.2 that the controller must always be able to demonstrate that personal data are processed in a transparent manner in relation to the data subject. Connected to this, the accountability principle requires transparency of processing operations in order that data controllers are able to demonstrate compliance with their obligations under the GDPR.
3. In accordance with Recital 171 of the GDPR, where processing is already under way prior to 25 May 2018, a data controller should ensure that it is compliant with its transparency obligations as of 25 May 2018 (along with all other obligations under the GDPR). This means that prior to 25 May 2018, data controllers should revisit all information provided to data subjects on processing of their personal data (for example in privacy statements/ notices etc.) to ensure that they adhere to the requirements in relation to transparency which are discussed in these guidelines. Where changes or additions are made to such information, controllers should make it clear to data subjects that these changes have been effected in order to comply with the GDPR. WP29 recommends that such changes or additions be actively brought to the attention of data subjects but at a minimum controllers should make this information publicly available (e.g. on their website). However, if the changes or additions are material or substantive, then in line with paragraphs 29 to 32 below, such changes should be actively brought to the attention of the data subject.
4. Transparency, when adhered to by data controllers, empowers data subjects to hold data controllers and processors accountable and to exercise control over their personal data by, for example, providing or withdrawing informed consent and actioning their data subject rights. The concept of transparency in the GDPR is user-centric rather than legalistic and is realised by way of specific practical requirements on data controllers and processors in a number of articles. The practical (information) requirements are outlined in Articles 12-14 of the GDPR. However, the quality, accessibility and comprehensibility of the information is as important as the actual content of the transparency information, which must be provided to data subjects.
5. The transparency requirements in the GDPR apply irrespective of the legal basis for processing and throughout the life cycle of processing. This is clear from Article 12 which provides that transparency applies at the following stages of the data processing cycle:

• before or at the start of the data processing cycle, i.e. when the personal data is being collected either from the data subject or otherwise obtained;
• throughout the whole processing period, i.e. when communicating with data subjects about their rights; and
• at specific points while processing is ongoing, for example when data breaches occur or in the case of material changes to the processing.
