    Gestion du consentement

    The Internet pages of the Luma-Metall AB use cookies. Cookies are text files that are stored in a computer system via an Internet browser.

    Many Internet sites and servers use cookies. Many cookies contain a so-called cookie ID. A cookie ID is a unique identifier of the cookie. It consists of a character string through which Internet pages and servers can be assigned to the specific Internet browser in which the cookie was stored. This allows visited Internet sites and servers to differentiate the individual browser of the dats subject from other Internet browsers that contain other cookies. A specific Internet browser can be recognized and identified using the unique cookie ID.

    Through the use of cookies, the Luma-Metall AB can provide the users of this website with more user-friendly services that would not be possible without the cookie setting.

    By means of a cookie, the information and offers on our website can be optimized with the user in mind. Cookies allow us, as previously mentioned, to recognize our website users. The purpose of this recognition is to make it easier for users to utilize our website. The website user that uses cookies, e.g. does not have to enter access data each time the website is accessed, because this is taken over by the website, and the cookie is thus stored on the user’s computer system. Another example is the cookie of a shopping cart in an online shop. The online store remembers the articles that a customer has placed in the virtual shopping cart via a cookie.

    The data subject may, at any time, prevent the setting of cookies through our website by means of a corresponding setting of the Internet browser used, and may thus permanently deny the setting of cookies. Furthermore, already set cookies may be deleted at any time via an Internet browser or other software programs. This is possible in all popular Internet browsers. If the data subject deactivates the setting of cookies in the Internet browser used, not all functions of our website may be entirely usable.
    4. Collection of general data and information

    The website of the Luma-Metall AB collects a series of general data and information when a data subject or automated system calls up the website. This general data and information are stored in the server log files. Collected may be (1) the browser types and versions used, (2) the operating system used by the accessing system, (3) the website from which an accessing system reaches our website (so-called referrers), (4) the sub-websites, (5) the date and time of access to the Internet site, (6) an Internet protocol address (IP address), (7) the Internet service provider of the accessing system, and (8) any other similar data and information that may be used in the event of attacks on our information technology systems.

    When using these general data and information, the Luma-Metall AB does not draw any conclusions about the data subject. Rather, this information is needed to (1) deliver the content of our website correctly, (2) optimize the content of our website as well as its advertisement, (3) ensure the long-term viability of our information technology systems and website technology, and (4) provide law enforcement authorities with the information necessary for criminal prosecution in case of a cyber-attack. Therefore, the Luma-Metall AB analyzes anonymously collected data and information statistically, with the aim of increasing the data protection and data security of our enterprise, and to ensure an optimal level of protection for the personal data we process. The anonymous data of the server log files are stored separately from all personal data provided by a data subject.

    ”_ga” is a cookie which terminates after 2 years.
    ”_gat” is a cookie which terminates after a minute.
    ”_gid” is a cookie which terminates after 24 hours.
