On Thursday, November 30th, Homo Digitalis submitted a request (reference number 865/30-01-2025) to the Hellenic Personal Data Protection Authority (HDPA), asking for the exercise of its investigative powers regarding the use of the Deepseek platform by data subjects within the Greek territory, in accordance with Article 58 of the General Data Protection Regulation (GDPR). The request is available here (ΕL).

In recent days, the Deepseek platform has become particularly popular among users within the Greek territory due to related media publications. Supervisory authorities from other EU member states, such as the Italian and Irish supervisory authorities, have already taken significant interventions to limit the use of the platform. This is because, based on the data processing practices taking place and the way they are described in its Privacy Policy, serious challenges to the protection of users’ personal data are apparent.

In the request we submitted, we are asking the HDPA, in accordance with Article 58(1)(a) and Article 58(2)(f) of the GDPR, to instruct the data controllers, namely Hangzhou DeepSeek Artificial Intelligence Co., Ltd. and Beijing DeepSeek Artificial Intelligence Co., Ltd., to provide all the information necessary to perform its duties in order to clarify the challenges to the rights of the data subjects we highlight in our submission. Furthermore, we request the HDPA to immediately impose restrictions on the processing of personal data of users within the Greek territory by the Deepseek platform, temporarily prohibiting its availability and use in the Greek market.

Today, Sunday, February 2nd, our statements are also featured in an article by journalist Giannis Papadopoulos in the Sunday edition of the newspaper “Kathimerini,” which provides a detailed description of the related developments, including statements from Professors Thodoris Christakis, Dimitris Papaheliopoulos, Vasilis Vlahos, and security researcher Dimitris Siatiras. We sincerely thank the journalist for his interest in our actions! For Homo Digitalis, comments were provided by Eleftherios Chelioudakis. You can read this press coverage online here.
