Cookies policy

1. What is a cookie?

A 'cookie' is a data file written on an user's computer hard drive by a website that identifies it and allows it to remember it, customize your preferences or eliminate the need to fill out forms or data in future visits. It also allows a website or advertising companies to monitor the browsing pattern or behaviour of users.

Users can configure browsers to alert them with an alert for the existence of 'cookies' on the visited websites, or to directly prevent cookies from being installed on your hard disks.

2.- Types of Cookies

Own Cookies: These are the ones that are sent to your computer by the website itself.
A typical example could be a cookie that a portal sends to its users to know in which language they prefer to read their content. When you select that you want to read the contents in Spanish inside the portal this will send you a cookie with your preferences. From that moment, whenever you have that cookie installed, the portal will show you the information in the language you have previously selected.

Third party cookies: These are those sent by other websites.
We use them in trenes.com and we explain them in detail below, but in summary, when you visit our website, Google Analitics sends a cookie to you in order to identify and follow your navigation on our website. In this case, the cookie is not stored by us directly, it is performed by Google as a free service.

3.- Types of cookies according to the term that remain active

All cookies are stored on your computer with an expiration time. If these cookies expire when the browser is closed we are talking about session cookies, on the contrary, if these remain in operation, even when you have closed the browser, we are talking about permanent cookies.

For example, one use of a session cookie would be when shopping online. When you select a product to buy it you are sent a cookie. With this cookie on your computer, the web can read it and recognize that you want that product and add it in your basket when shopping online. Without this cookie you will not be able to differentiate it from the rest of the visitors. Once the process is complete the cookie is deleted from your computer.

An example of a permanent cookie: An online store that sees that you are interested in one of their products could send a cookie with that data 'this visitor is interested in my series of cameras of the brand Canon' and with that cookie installed it would show banners advertising that product in the following days.

4.- Types of cookies according to their purpose

According to their purpose we can distinguish the following cookies:

Technical Cookies: Generally sent by the site itself that facilitate the navigation through the portal. An example could be the social network Facebook. When you add your username and password, Facebook sends you a cookie to identify it from the rest of your visitors and show your personal information which is restricted to other users.

Personalization Cookies: These are the ones that save your preferences within the portal, for example your language.

Analysis Cookies: They are used to evaluate how users use the website. Data like what pages do they visit, how many seconds they stay in each section, etc ... These cookies are useful for improving the services that a portal gives based on how users interact with it.

Advertising Cookies: They are used to customize the advertising that a portal displays to its users based on the content of the website and the frequency at which the ads are displayed.

Behavioural Advertising Cookies: These cookies store the information of the users and their behaviour so that they can offer in the available advertising spaces information which might be relevant to the user.
