The CNS and personal data protection

The CNS only processes your personal data to fulfil its legal missions. In this context, it may have to pass your information to other organisations associated with social security.

All these organisations, including the CNS, must respect the legal framework relating to the protection of personal data.

Regulation 2016/679 of the European Parliament and of the Council on the protection of natural persons with regard to the processing of personal data and on the free movement of such data (GDPR) took force on 25 May 2018.

The GDPR places additional responsibilities on anyone processing personal data.

The CNS assures you that your personal data is well protected. The CNS Data Protection Officer (DPO) works full-time to protect personal data. In addition, the CNS maintains a list of all the operations it carries out that involve the processing (collection, use, storage, transfer) of your personal data.
