@synapxlab/cookie-consent manages the collection, recording, and proof of consent for trackers (cookies, localStorage, etc.), via an optional logging system. The website operator integrating this module remains responsible for the processing of collected data, including consent logs. This component does not constitute legal advice and does not replace a complete GDPR compliance solution (processing register, DPIA, DPA, rights management, etc.). Always validate your configuration with your DPO or legal counsel.
Note on exempted analytics: Cookie Consent manages consent for trackers that require it. For audience measurement tools exempted according to CNIL criteria, refer to CNIL documentation for their compliant deployment.
