Cookie List
A cookie is a small piece of data (text file) that a website - when visited by a user - asks your browser to store on your device in order to remember information about you, such as your language preference or login information. Those cookies are set by us and called first-party cookies. We also use third-party cookies - which are cookies from a domain different than the domain of the website you are visiting - for our advertising and marketing efforts. More specifically, we use cookies and other tracking technologies for the following purposes:
Strictly Necessary Cookies

They are usually only set in response to actions made by you which amount to a request for services, such as setting your privacy preferences, logging in or filling in forms. You can set your browser to block or alert you about these cookies, but some parts of the site will not then work. These cookies do not store any personally identifiable information.
