Data processing

The intervention framework of the PEReN is mainly declined according to three modalities defined by its creation decree and the law of October 25, 2021:

All data processing carried out by PEReN is in compliance with the General Data Protection Regulation (RGPD) and the French Data Protection Act.

Experimentation and automated data processing

The experiments conducted by PEReN are proofs of concept that can rely on the collection and exploitation of publicly accessible content from digital platforms. In this context, the data collected :
  • are kept for no longer than nine months;
  • are not used for any purpose other than the development of a tool or test.
An experiment may consist in designing a digital tool to verify whether a platform's algorithm is fair or works as described, and personal data may be collected during the tests carried out (for example, the names of users who have left comments on a page). These collections are specifically implemented under the conditions and limits provided by Decree No. 2022-603 of April 21, 2022 (articles 2 to 6) and comply with the rules specified in the PEReN Decision of July 1, 2022 .

Each experimentation provides for:
  • minimization of the data collected: only strictly necessary data are collected;
  • the use of secure protocols for content retrieval and processing;
  • the recording of all the operations carried out within the framework of the treatment of the collected data: consultation, modification, communication, deletion. This recording is kept for three years.
  • the automatic destruction of all data collected at the end of the work and at the latest nine months after their collection.

Exercising your rights

As part of its activities defined by the October 25, 2021 law and the August 31, 2020 decree, PEReN is currently conducting projects that may lead to the collection of personal data regarding the following platforms:

In the same context, PEReN may also use the following pre-trained models or training datasets:


In accordance with the French Data Protection Act of January 6, 1978, you have the right to access, rectify, limit, oppose and delete data concerning you that may be collected in the context of these experiments and research projects. Data will be deleted no later than 9 months after collection, unless otherwise specified in the case of public research projects
You can exercise this right by sending a message to the PEReN team: refdcp.peren [at]
