Cookies policy of Iberdrola España
What are cookies?
Cookies are small, widely-used files or devices that are installed on the user's browser in order to store, retrieve or update data. They enable a website administrator to record user preferences when browsing the website and customise the services offered based on those preferences.
On www.iberdrolaespana.com we use first-party and third-party cookies for usage analysis and measurement purposes to make sure that our website is working properly and to enable us to improve our services.
The third-party Cookies Iberdrola España, S.A.U. (hereinafter "Iberdrola España") uses to obtain information on visits, measure and analyse browsing habits on the website and customise some services are owned by OneTrust and Google Universal Analytics. Only Google Universal Analytics has access to the data collected by its devices.
Types of cookies
Depending on their purpose, cookies can be:
Technical cookies: technical or necessary cookies are essential for a website to function properly and include basic functionalities such as identifying the session or giving registered users access to restricted access areas. This is why technical cookies cannot be deactivated.
Statistical cookies: these are cookies that allow us to see how the user interacts with the website, collecting anonymous information during the time they are browsing. The purpose of collecting this information is to make improvements to the web based on analysis of the aggregated data.
Preference cookies: these are cookies that allow the website to remember information during a user's browsing time associated with the way the page behaves or looks, such as the preferred language or the region in which they are located.
Marketing cookies: marketing or advertising cookies are used to analyse a user's behaviour while visiting the website and so that, from time to time, other providers can offer personalised and relevant advertising depending on the browsing profile.
Depending on who owns the cookies, they can be:
First party cookies: these are those that are sent to a computer or device (for example: computer, mobile or tablet) from a computer or domain managed by a website and from which the service requested is provided.
For example, the cookie that we use to manage consent (OptanonConsent) is generated by Iberdrola España from its website and sent to your computer or device to keep a record of your consent.
Third-party cookies: these are those that are sent to your computer or device by another entity other than the owner of the website that processes the information obtained through cookies.
For example, if the website operates video viewing via YouTube (external to Iberdrola España), this provider will display certain cookies so that the video can work. These cookies are not sent by Iberdrola España to your computer or device; they are sent directly by YouTube.
Depending on how long they remain activated on your computer, cookies can be:
Session cookies: these are cookies designed to compile and store data while the user is visiting the website.
Persistent cookies: these are cookies designed to keep the data stored on the user's device so they can be accessed and processed for a period of time defined by the cookie manager. This period may vary from a few minutes to several years.
