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 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.
Enabling cookies is not needed for the website to display public information. If you have an account, however, cookies are needed to log you into your account.
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.
You can control and/or delete cookies as you wish. You can delete all cookies that are already on your computer and you can set most browsers to prevent them from being placed. For details, see aboutcookies.org.
