What are cookies?
Cookies are small data files sent by a website’s server to a web browser, processor memory or hard drive and stored there. They can be used for a range of different purposes, such as customising a website for a particular user, helping a user navigate a website, improving that user’s website experience, and storing that user’s preferences and login information.
Essential and non-essential cookies
Cookies can be classified as either ‘essential’ or ‘non-essential’.
Essential cookies: these are cookies that are either:
- used solely to carry out or facilitate the transmission of communications over a network; or
- strictly necessary to provide an online service (e.g. our website or a service on our website) which you have requested.
Non-essential cookies: these are any cookies that do not fall within the definition of essential cookies, such as cookies used to analyse your behaviour on a website (‘analytical’ cookies) or cookies used to display advertisements to you (‘advertising’ cookies).
Cookies can be classified as either ‘session’ or ‘persistent’, depending on how long they last after they are placed on your browser.
- Session cookies: session cookies last for as long as you keep your browser open. They expire when you close your browser.
- Persistent cookies: persistent cookies expire at a fixed point in time or if you manually delete them from your browser, whichever occurs first.
Cookies can be classified as ‘first party’ or ‘third party’.
- First party cookies: these are cookies placed on your device by our website domain.
- Third party cookies: these are cookies placed on your device by third party website domains.
