What are cookies?
Cookies are small text files or storage devices that are downloaded to the user’s computer, smartphone, tablet, or other device when accessing certain web pages. Cookies allow the website to remember the user’s actions and preferences (for example, selected language, font size, and other display preferences) for a certain period, so they do not have to be reconfigured every time you return to the site or browse its pages.
In more technical terms, cookies are information files that a website’s server sends to the user’s browser (Explorer, Firefox, Chrome, Safari, etc.) and which are stored on their device. The information collected through cookies may include the date and time of visits to the site, the pages viewed, the time spent on the site, and the sites visited just before and after it, among other aspects.
Cookies fulfill a wide variety of functions, such as recognizing you as a user, obtaining information about your browsing habits, or customizing the way content is displayed. They can also be used to improve the security of the web and for statistical or advertising purposes.
It is important to note that cookies do not damage the user’s device. In many cases, they are deleted automatically after a certain time (for example, at the end of the browsing session, in the case of session cookies). In others, they may remain on the device to remember information on successive visits to the same website, without prejudice to the user’s ability to delete them at any time.
Types of Cookies Used
At aruxingenieria.com we mainly use the following types of cookies, according to the purposes they pursue:
-
Technical or strictly necessary cookies: These are essential for the proper functioning of the website and the provision of the services offered. They allow navigation through the page and the use of its different basic options or services. For example, controlling traffic and data communication, identifying the session, accessing restricted areas, remembering the elements that make up an order, applying for registration or participation in an event, using security elements during navigation, storing the user’s preference on cookie acceptance, etc. These cookies do not require the user’s consent, as their use is based on the need to guarantee the technical operation of the website. On our site, we may use our own technical cookies, for example, to remember if the user has accepted (or closed) the cookie notice, preventing it from being shown repeatedly.
-
Analysis or measurement cookies: These are cookies, either our own or from third parties, that collect information, in an anonymous or pseudonymized way, about how users interact with the website, with the purpose of understanding visitor behavior and thus being able to improve the user experience. In our case, we use third-party cookies provided by the Google Analytics service to obtain aggregate statistics on visits (number of visitors, browsing time, most viewed pages, approximate geographic origin of the visit, etc.). These cookies help us understand how users use the web and thus be able to optimize its content and services. Although these analysis cookies do not directly identify the user (Google Analytics uses IP anonymization methods, for example), they collect information that could be considered personal (such as IP address, online identifiers associated with the device, etc.), so they require the user’s consent for their installation.
On the other hand, on this site we do not use behavioral advertising or profiling cookies that store browsing habits to offer targeted advertising, nor other third-party cookies apart from the analytical ones mentioned. In the event that these types of cookies are used in the future, the user will be informed in advance and their corresponding consent will be sought.
Cookies we use on aruxingenieria.com
Below are the specific cookies used on our website, along with their purpose and approximate duration:
-
cookie_notice_accepted (Own technical cookie): This cookie is used to remember the user’s preference regarding the cookie notice. It indicates if the user has already accepted the cookie policy so as not to show the notice banner again. Duration: persistent, usually expires in 1 year.
-
_ga (Analysis cookie – Google Analytics): Used to distinguish users by assigning an anonymous identifier. It is a third-party cookie (domain: aruxingenieria.com / Google) of a persistent type, with a typical duration of 2 years.
-
_gid (Analysis cookie – Google Analytics): Used to distinguish users and store statistical information on how the user uses the web in an aggregate way. It is persistent but short-term, with a duration of 24 hours.
-
_gat (Analysis cookie – Google Analytics): Used to limit the number of requests made to Google Analytics, avoiding server overload. It has a very short duration, approximately 1 minute. (Note: Google Analytics cookies may be defined with slightly different or additional names depending on the version and configuration implemented; for example, Google Analytics 4 may use cookies with the “_ga” prefix followed by an additional identifier. However, their function remains audience analysis.)
Important: The information collected by Google Analytics cookies is transmitted to and stored by Google on its servers, which may be located in the United States or other countries outside the EU. Google may use this information on behalf of the Owner for the purpose of evaluating the use of the website, compiling activity reports, and providing other services related to the site’s activity. Google undertakes not to associate the user’s IP address with any other data it may have. In any case, the user can reject the use of Google Analytics cookies by not granting their consent in the initial banner, or by configuring their browser to block them (see the next section). Please note that if the user chose to reject analytical cookies in the initial cookie banner, Google Analytics will not be installed and therefore will not collect your browsing information.
Third parties (in this case, Google) are solely responsible for the correct operation and use of the cookies they manage. The Owner has configured Google Analytics to operate anonymously (masking users’ IP addresses so that they are not recorded in full) and has signed the corresponding data processing agreement with Google, which stipulates that this data will be used solely for the indicated purpose.
