We at Cerdá Group wishes to inform you that our website uses cookies to analyse the navigation habits of our USERs. Cookies are files that are installed in the browser from which you access our website for the purposes described on this page. Cookies are used on the Internet for many purposes; a cookie usually identifies an access point so that the website you are visiting knows what actions you perform on your visit (for example, to identify whether you are signing up or whether you are logged in). In the worst case, a cookie can be used to offer you advertising that is filtered to match your interests (based on your browsing habits) and this can pose a privacy problem. For example, a social network or a search engine, instead of offering you random publicity, could offer you an advertisement targeted to what they would consider are "your interests" because they would supposedly control which websites you visit thanks to the installation of their scripts or social buttons on websites around the world. That is why the Internet law (according to paragraph 2 of Article 22 of the LSSI) obliges us to inform you of cookies that could endanger your privacy before you install them, with cookies intended purely for usual navigation exempt from this law.

We can classify cookies into two types: own and third-party cookies.
  - Own cookies  (from cerdagroup.com) are generated by us and therefore we can guarantee that these are cookies intended solely for the navigation of our website and that, therefore, are exempt from the application of Internet law (for further information, please see pages 4 and 5 of the "Guide for the use of cookies" from the Spanish Data Protection Agency: http://www.agpd.es/portalwebAGPD/canaldocumentacion/publicaciones/common/Guias/Guia_Cookies.pdf ) 
- Third-party cookies , however, are not installed by us, but come with the various standard plugins we use (for example, video insertion plugins, maps, "like" buttons or visitor analyses). We are unaware of fraudulent practices existing on the part of these companies when handling your privacy, but as these companies are independent from Cerdá Group we cannot guarantee the cookies that are installed, or their purpose. Therefore, the name and number of those third-party cookies that we mention on this Cookies Policy Page refer exclusively to the cookies that we have detected on the date that this page was last revised, and note that these could change over time Therefore, when visiting our website, our own cookies intended for navigation will be installed by default, and third party cookies will be installed only if you accept our Privacy Policy, according to the notice that appears in the header, if appropriate. Applying the law in this case involves controlling all content, item by item, that contains some third-party plugins, so we are constantly reviewing content, especially older content. If you detect a case, please let us know using our Contact Section, indicating the URL of the website so that we can update it as described. Third party cookies are usually installed under the domain name of such third party (YouTube, Facebook, Google, etc.), so you may have these cookies installed because you have visited other websites and accepted their own Cookies Policies. In order to verify which cookies are installed by each website, you will need to have a single webpage (tab) open in your browser, remove all cookies, navigate the particular website and then once again review any cookies are installed. This process will cause the browser to delete any preferences you had included concerning websites you have visited, so if you have chosen to remain logged in to a network or site, or saved a password then you will simply have to login again, so it may be advisable not to use your usual browser to undertake this activity.
