To make this site work properly, we sometimes place small data files called cookies on your device. Most websites do this too.
A cookie is a small text file that a website saves on your computer, tablet or mobile device when you visit the site. It enables the website to remember your actions and preferences (such as login, language, font size and other display preferences) 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 (this data is collected anonymously) and the pattern data is fully under our control. These cookies are not used for any purpose other than those described here.
