Cookie Notice

Effective 14 October 2026. CLIREN uses essential cookies for security, sessions, account sign-in, forms, preferences and shopping functions. Optional analytics or campaign measurement may be used to understand aggregated site use and improve journeys.

Your choices

Essential cookies cannot be disabled through the site because core functions depend on them. Optional analytics should operate according to the consent choices presented on the site. Browser controls can remove or block cookies, but doing so may affect sign-in, checkout or learning functions.

Third-party services

Embedded media, payment services and connected learning tools may set their own cookies under their notices. CLIREN does not send passwords, research records, payment-card data or free-text service enquiries to general marketing analytics.
