The data from the Ecmoss surveys are protected by statistical secrecy and are intended for INSEE and DARES (the statistical service of the Ministry of Labour).

These responses, as well as the data obtained by matching, are kept for 5 years from the end of the collection for the purposes of the survey. They will be archived beyond this period. At all times, their use and access are strictly controlled and limited to the compilation of statistics or to scientific or historical research.

The General Regulation 2016/679 of the European Parliament and of the Council of 27 April 2016 on data protection (RGPD) as well as the (French) law n°78-17 of 6 January 1978 on data processing, files and freedoms apply to these surveys. For personal data, a right of access, rectification, deletion or limitation of processing may be exercised during the 6-month retention period for identification data.
