What are cookies?
Cookies are short text files downloaded to your device by a website. Cookies are normally used to provide a more personalized experience and to remember a user’s profile without the need for a specific login. Also, it can be placed by third parties (such as an advertising network) in end users’ devices and may be used to track users when surfing across different websites associated with that third party.
First-party cookies are cookies set by the website you are visiting. Only that website can read them. In addition, a website might potentially use external services, which also set their own cookies, known as third-party cookies.
Persistent cookies are cookies saved on your computer that are not deleted automatically when you close your browser, unlike a session cookie, which is deleted when you leave your browser.
What is the duration of cookies?
We may use “session cookies” or “persistent cookies.” Session cookies are temporary and expire once you close your browser or once your session ends. Persistent cookies remain on your device for much longer or until you or your browser erase them. Persistent cookies have varying durations that are dependent on their expiration date. For more information about the specific duration of cookies used, please see Addendum 1 entitled “Active Cookie Collection List” below.
What are the main types of cookies?
Essential/Functional Cookies. These cookies enable core functionality such as security, network management, and accessibility. You may disable these by changing your browser settings, but this may affect how the website functions.
Analytics Cookies. Analytics cookies are used internally for improving your website experience. The cookies assess your interactions with the website – as an anonymous user (the data gathered does not identify you personally). The data is not shared with any third parties or used for any other purpose. The cookies can be either accepted or refused by you – either through selecting your preference in the bottom of this page or the site's cookie banner when you first visit the site.
Marketing Cookies. These cookies track your online activity to help deliver advertisements that are relevant to you and your interests and measure the effectiveness of the advertising campaigns. They also limit how many times you see a certain advertisement. The information collected through these cookies may be shared with others, such as advertisers.
