Your PLATO database uses only one cookie.

If you click the “Keep Me Logged In” checkbox, the database uses a cookie on your computer to remember you. So you don’t have to keep entering your username and password every time you log in.

We classify this as an ‘essential’ cookie. We do not use any ‘non-essential’ cookies to provide information for advertisers, etc

If you continue to use the “Keep Me Logged In” facility, we'll assume that you are happy to receive the cookie that helps with this function.
