Processing related to platform security and technical analysis is based on our legitimate interest (GDPR article 6.1.f): maintaining a high level of security and the proper technical operation of the site.

Application files are kept for 12 months after each edition of the competition closes. Technical logs are kept for up to 6 months.

7. Data recipients

Access is limited to Association Entrelacé members in charge of running the competition, and to the following technical providers, bound by confidentiality obligations:

The platform and the team managing it implement the following measures:
