What are cookies?

Cookies are a set of data that a server deposits in the user’s browser to collect standard Internet log information and visitor behavior data on a website. In other words, they are small text files stored on the computer’s hard drive that serve to identify the user when they reconnect to the website. Their purpose is to record the user’s visit and save certain information. Their use is common and frequent on the web because they allow pages to function more efficiently and achieve greater personalization and analysis of user behavior.

 

What types of cookies exist?

The cookies used on our website are session cookies and third-party cookies, and they allow us to store and access information related to language preferences, the type of browser used, and other general characteristics predefined by the user, as well as track and analyze the activity carried out with the aim of making improvements and providing our services in a more efficient and personalized manner.

Cookies, depending on their duration, can be divided into session or persistent cookies. Session cookies expire when the user closes the browser. Persistent cookies expire based on when their purpose is fulfilled (for example, to keep the user logged into Eugenio Trillo León’s services) or when they are manually deleted.

Additionally, depending on their purpose, cookies can be classified as follows:

 

Performance Cookies

This type of cookie remembers your preferences for tools found in the services, so you don’t have to reconfigure the service every time you visit. For example, these include: volume settings for video or sound players, video transmission speeds that are compatible with your browser, and items saved in the “shopping cart” in e-commerce services like stores.

 

Geolocation Cookies

These cookies are used to determine which country you are in when you request a service. This cookie is completely anonymous and is only used to help direct content to your location.

 

Registration Cookies

Registration cookies are generated once the user has registered or has subsequently opened their session, and they are used to identify the user in the services with the following objectives:

  • Keeping the user identified so that if they close a service, the browser, or the computer, and later re-enter the service at another time or another day, they will remain identified, thus facilitating navigation without needing to re-enter their credentials. This functionality can be disabled if the user clicks the [log out] option, in which case the cookie will be deleted, and the next time they enter the service, they will need to log in again to be identified.
  • Checking if the user is authorized to access certain services, for example, to participate in a contest.

Additionally, some services may use connectors to social networks like Facebook or Twitter. When the user registers for a service with social network credentials, they authorize the social network to save a persistent cookie that remembers their identity and guarantees access to services until it expires. The user can delete this cookie and revoke access to the services via social networks by updating their preferences on the specific social network.

 

Analytics Cookies

Every time a user visits a service, a tool from an external provider generates an analytical cookie on the user’s device. This cookie, which is only generated during the visit, will serve in future visits to the services of Eugenio Trillo León to anonymously identify the visitor. The main goals pursued are:

  • Allowing the anonymous identification of browsing users through the cookie (identifies browsers and devices, not people) and thus enabling the approximate counting of the number of visitors and their trend over time.
  • Anonymously identifying the most visited content and therefore the most attractive to users.
  • Knowing whether the user is new or a repeat visitor.

Important: Unless the user decides to register for a service from Eugenio Trillo León, the cookie will never be associated with any personal data that could identify them. These cookies will only be used for statistical purposes to optimize the user experience on the site.

 

Advertising Cookies

This type of cookie allows for expanding the information of the ads shown to each anonymous user on the services of Eugenio Trillo León. Among other things, it stores the duration or frequency of viewing of advertising positions, the interaction with them, or the user’s navigation patterns and/or behaviors, as they help to create a profile of advertising interests. In this way, it allows advertising to be offered that matches the user’s interests.

 

Third-party Advertising Cookies

In addition to advertising managed by the websites of Eugenio Trillo León within their services, the websites of Eugenio Trillo León offer advertisers the option to serve ads through third parties (“Ad-Servers”). Thus, these third parties can store cookies sent from the services of Eugenio Trillo León from users’ browsers and access the data stored in them.

The companies that generate these cookies have their own privacy policies. Currently, the websites of Eugenio Trillo León use the Doubleclick (Google) platform to manage these services. For more information, visit:
