To make the website of Lhoist work properly, we sometimes place small data files, called cookies, on your device. 

1. What are cookies?

A cookie is a small text file that a website stores on your computer or mobile device when you visit our website. 

  • First party cookies are cookies set by the website you’re visiting. Only that website can read them. In addition, our website uses also external services, which also set their own cookies, known as third-party cookies. 

  • Persistent cookies are cookies saved on your computer and that are not deleted automatically when you quit your browser, unlike a session cookie, which is deleted when you quit your browser. 

Every time you visit the Lhoist website, you will be prompted to accept or refuse cookies. 

The purpose is to enable the site to remember your preferences (such as language, etc.) for a certain period of time. That way, you don’t have to re-enter this information when browsing around the site during the same visit. Cookies can also be used to establish anonymized statistics about the browsing experience on our sites.
