Cookies and local storage are part of the technology necessary for a website operation and both are not inherently harmful, but it is important that you know the implications that they have for your privacy.


A cookie is a small text file that is stored on the user's device (computer, phone, tablet, etc.) when it is visited almost any web page.

Among others, Cookies allow a web page to store and retrieve technical information, personal preferences, content customization, usage statistics, links to social networks, access to user accounts, etc.

The user's browser memorizes the cookies on the hard drive (or its equivalent), occupying a minimum memory space and not harming the computer (or device).

Cookies do not contain any kind of specific personal information and most of them are deleted at the end of the browser session (session cookies).

Once a website creates a cookie, the user's device store the following information:

  • The address / domain of the web that created the cookie.
  • The duration of the cookie, which can be from a few minutes to several years.
  • The content of the cookie.
Most web browsers accept cookies as a standard and, regardless of them, they allow or prevent temporary or memorized cookies in the security settings.

The user can configure their browser at any time to prevent (block) the use of cookies by certain websites, as well as delete previously stored cookies.


  • Essential technical cookies: These are those that allow the user to navigate through a web page, platform or application and use the different options or services that exist in it, such as, for example, controlling traffic and data communication, identify the session, access parts of restricted access, remember the elements that form an order, carry out the process of purchasing an order, make a request for registration or participation in an event, use security elements while browsing, store content to broadcasting videos or sound or sharing content through social networks. When disabling them, it is possible that some section of the web does not work correctly.

  • Personalization cookies: These are those that allow the user to access the service with some predefined general characteristics based on a series of criteria in the user's terminal, such as the language, the type of browser through which the user accesses the service, the locale from where you access the service, etc.

  • Analysis cookies: These are those that, processed by us or by third parties, allow us to quantify the number of users and thus carry out statistical measurement and analysis of the use made by users of the service. For this, we can analyze the navigation in order to improve the offer of products or services.

  • Behavioral advertising cookies: These are those that allow the management, in the most efficient way possible, of the advertising spaces that, where appropriate, the editor has included in a web page, application or platform from which the requested service is provided. These cookies store information on the behavior of users, obtained through the continuous observation of browsing habits, which allows the development of a specific profile to display advertising based on it.

  • Cookies for social sharing: These are those that allow the user to be identified in their social networks and thus allow him to share content.


Local storage means any file created by the web on your browsing device. Cookies are a form of local storage, but there are others, as example:

  • The browser's local storage: Some websites use local storages called "sessionStorage" and "localStorage" to store information; "sessionStorage" is automatically deleted when the browser program is closed; instead to delete the "localStorage" the user must delete the browsing history.

  • Flash local storage (Flash Local Shared Objects): Flash is a browser add-on that allows you to incorporate interactive and multimedia elements on a web. Flash also allows the visited website to store files on the user's device.

  • Silverlight local storage (Isolated Objects): Silverlight is a browser add-on that allows you to incorporate interactive and multimedia elements on a web. Silverlight also allows the visited website to store files on the user's device.

  • The web beacon: It is a tracking technique that consists of inserting an image hosted on an Internet server on the web or in an email so that, when the browser or email program connects to said server to download and view the image, the access is logged. Sometimes these images are very small or transparent so that the user is not aware of their existence.

Among them are session cookies, used to remember the website navigation options chosen by the user.
