The cookies we set and why.
Strictly necessary
A session cookie keeps you signed in. It is HttpOnly, Secure and SameSite=Lax, and it is required for the site to function.
Preferences
A language cookie remembers whether you chose the English or Chinese site, so you are not switched back automatically.
No advertising cookies
We do not set advertising or cross-site tracking cookies. Bot-protection on sensitive forms is provided by a challenge that sets its own short-lived cookie.
