1. What are cookies and what do we use them for?
A cookie is a small file of information that is stored on your computer, smartphone or tablet when you visit a website. It contains no viruses and cannot harm your device, but it may collect information about you, such as your browsing habits or preferences. That is why, except for technical cookies, they require your prior consent. This policy also covers similar technologies, such as the browser’s local storage.
- By purpose: technical cookies are necessary for the website to work, do not require your consent and are the only ones enabled by default. Other cookies are used to analyse how the website is used, to personalise it or to show advertising.
- By who manages them: first-party cookies are our own; third-party cookies belong to external companies that provide services for our website, some of them located outside Spain.
- By duration: session cookies are deleted when you close your browser; persistent cookies remain on your device for a set period.
