What is used now
- Authentication and security cookies supplied by the selected sign-in provider.
- Checkout security cookies set on the payment provider’s own pages.

Analytics and advertising
No optional analytics or advertising tracker is enabled in this release. If CasaCerta later introduces non-essential analytics, personalisation or advertising storage, it must remain off until the visitor makes a clear choice, and that choice must be as easy to withdraw as to give.
Your controls
You can remove the language preference through browser site-data controls. Blocking strictly necessary authentication or security storage may prevent account, enquiry or payment features from working.
