What are ‘cookies’?

‘Cookies’ are small text files that are stored by the browser (for example Chrome or Safari) on your computer or mobile phone. They allow websites to store things like user preferences. You can think of cookies as providing a ‘local memory’ for the website so that it can recognize you when you come back and respond appropriately.


Are cookies dangerous?

No. Cookies are small pieces of text. They are not computer programs, and they can't be executed as code. Also, they cannot be used to disseminate viruses.
