Cookie Policy
This is a translation provided for convenience only. In the event of any discrepancy, the French version alone is legally binding.
This page explains how SYNAPTIIK uses cookies and similar technologies (localStorage, sessionStorage, pixels, technical fingerprints). In line with CNIL recommendations and the ePrivacy Directive, your choices are respected equally for all cookies that are not strictly necessary.
1. What is a cookie?
A cookie is a small text file stored on your device when you visit a website. It allows information to be remembered (preferences, authentication session, audience measurement) between two visits.
2. Consent banner
On your first visit, a consent banner offers 3 buttons of equal visual weight, in line with the CNIL recommendation of 17 September 2020:
- Accept all — consent to all non-necessary categories;
- Reject all — rejection of all non-necessary categories, with the same visibility as the accept button;
- Customize — opens a fine-grained settings panel, category by category.
No box is pre-checked. Non-necessary cookies are only activated after an explicit action.
You can change your choices at any time via the "Cookie settings" link in the footer.
