Transparent choices for a more responsible web.
Policy version 1.0 · Last reviewed September 2026
This Cookie Policy explains how NEST uses cookies and similar technologies on this website. Our approach is deliberately simple: we try to use the minimum technology needed to run NEST, keep our digital footprint lightweight and give visitors a clear choice whenever optional technologies are involved.
Some technologies are essential for the website to work securely and remember your privacy choices. Others, such as analytics or external media, are optional and are kept inactive until you decide to allow them. You can accept all optional technologies, reject them, or choose individual categories. Rejecting optional cookies does not prevent access to the main content of NEST.
How cookies work on NEST
Cookies are small files or pieces of information that a website can store on your device. They may be used to keep a service secure, remember a preference, understand how a website is used or load content supplied by another provider.
The website owner and controller for this Cookie Policy is NEST. Privacy-related questions can be sent to admin@nestspain.org.
Essential
Required for security, consent preferences and core website functions. These remain active because the site cannot operate properly without them.
Analytics
Used only with permission to understand aggregated website use and improve content, navigation and performance.
External media
Used only with permission to load content supplied by third parties, such as video or map providers.
Cookies currently registered
The table below lists the cookies currently registered in NEST Green Consent. It should be reviewed whenever the website adds, removes or changes analytics tools, embeds or other services.

Your choices remain under your control
Optional technologies stay disabled until you choose to allow the relevant category. You can change or withdraw that choice at any time by selecting . Withdrawal applies to future use of optional technologies and does not affect processing that was lawful before the withdrawal.
You can also delete or block cookies through your browser settings. Browser controls are separate from the preferences stored by NEST and may affect how this and other websites work.
External content and third-party services
Some NEST pages may include videos, maps or other material supplied by external services. When you have not consented to external media, NEST attempts to prevent those embeds from loading and shows a privacy placeholder instead. If you choose to load the content, the external provider may receive technical information or set its own cookies under its own terms.
Legal framework and official references
NEST's cookie approach is designed around European data-protection rules and the Spanish rules governing storage and access to information on a user's device. In practical terms, optional cookies should be based on a clear choice, information should be understandable and accessible, and withdrawing consent should be as easy as giving it.
