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

Performance Cookies
This type of cookie remembers your preferences for the tools found in the services, so you don’t have to reconfigure the service every time you visit. For example, this category includes: Volume settings for video or sound players. Video transmission speeds compatible with your browser. Items saved in the “shopping cart” in e-commerce services such as stores.
Geo-localization Cookies
These cookies are used to determine which country you are in when a service is requested. This cookie is completely anonymous, and is only used to help tailor content to your location.

Registration Cookies
Registration cookies are generated once the user has registered or subsequently logged in, and are used to identify you in the services with the following objectives:
Keep the user identified so that, if they close a service, the browser or the computer and at another time or another day re-enters that service, they will remain identified, thus facilitating their navigation without having to identify themselves again. This functionality can be suppressed if the user clicks the [cerrar sesión] functionality, so that this cookie is deleted and the next time the user enters the service, they will have to log in to be identified.
Check if the user is authorized to access certain services, for example, to participate in a contest.
Additionally, some services may use connectors with social networks such as Facebook or X. 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 them access to the 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
Each time a user visits a service, a tool from an external provider generates an analytics cookie on the user’s computer. This cookie, generated only during the visit, will be used in future visits to BLS services to anonymously identify the visitor. The main objectives pursued are:
To allow anonymous identification of browsing users through the cookie (identifies browsers and devices, not people) and therefore the approximate counting of the number of visitors and their trend over time.
To anonymously identify the most visited content and therefore the most attractive to users. To know if the accessing user is new or a returning visitor.
Important: Unless the user decides to register for a BLS service, the cookie will never be associated with any personal data that could identify them. These cookies will only be used for statistical purposes that help optimize the user experience on the site.

Advertising Cookies
This type of cookie allows extending the information of ads shown to each anonymous user in BLS services. Among others, the duration or frequency of display of advertising positions, interaction with them, or user browsing patterns and/or behaviors are stored as they help form an advertising interest profile. In this way, they allow offering advertising relevant to the user’s interests.

Third-Party Advertising Cookies
In addition to the advertising managed by BLS websites in their services, BLS websites offer their advertisers the option to serve ads through third parties (“Ad-Servers”). In this way, these third parties can store cookies sent from BLS services originating from user browsers, as well as access the data stored in them.
The companies that generate these cookies have their own privacy policies. Currently, the BLS website uses the Google Marketing Platform platform to manage these services. For more information, please visit https://policies.google.com/
