What cookies are
A cookie is a small file placed on a device by a website, which allows the site to recognise the device on later visits. Cookies may be session-based, meaning they are removed when the browser closes, or persistent, meaning they remain for a set period.
They may be set by the site itself or, where permitted, by third-party services used on the site. Cookies do not themselves identify a person, but they may be linked to information held about a visit.
- Session Removed when the browser closes. Used to hold a state for one visit.
- Persistent Remain on the device for a set period, up to the expiry the service declares.
- Third-party Set by a service the site depends on — hosting, delivery, or analytics — under its own policy.
