Headquartered in France and handling data that concerns residents of the European Union, Mersen also complies with the fundamental principles of the revised version of the French data protection law of January 6, 1978 and European Regulation no. 2016/679 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data.

This privacy policy seeks to protect personal data and applies to all Mersen Group entity and subsidiary employees responsible for the management of personal data, from its collection and processing to its use, distribution, transfer and storage (hereinafter “Data Controllers”). This policy guarantees a high level of personal data protection in all countries.

The purpose of this policy is to provide an overview of the way in which Mersen operates with a broad spectrum of Data Subjects (customers, external service providers, prospective clients, etc.). Accordingly, not all provisions may apply to you.
