What are cookies?
A cookie is a small piece of text sent to your browser by a website that you visit. It enables the website to remember your actions and preferences (such as language) over a period of time, so you don't have to keep re-entering them whenever you come back to the site or browse from one page to another.
The cookie-related information is not used to identify you personally and the pattern data is fully under our control. These cookies are not used for any purpose other than those described here.
