sid | Set on your first visit. It protects our forms against cross-site attacks and keeps you logged in when you sign in. | Up to 30 days after your last visit |
sk_chat_v1 (local storage) | Only once you start a live chat: keeps the conversation open as you move between pages (see Live chat). | Cleared the next time you visit after 24 hours without using the chat, or straight away when you choose "Start a new chat" |
