Consent and future changes

In the current configuration, ECK has activated no non-essential service, so no consent banner is displayed. Any future analytics, marketing or other non-essential service will remain blocked until consent is obtained where required by law; refusing consent will be as easy as giving it, and this page will be updated.

Current technical state

The code controlled by ECK does not activate any non-essential cookies, advertising or marketing tools, or additional third-party analytics tools. The hosting platform nevertheless measures website traffic automatically through technical data and may use mechanisms strictly necessary for transmission, delivery and security.

Any future non-essential cookie or storage mechanism will remain blocked until consent is obtained where required by law; refusing or withdrawing consent will be as easy as giving it. CNPD · cookie rules ↗
