What are cookies?
Cookies are small files written to your computer by websites. They can contain anything but are usually used to store information about you which that website can then read back in next time you visit it.
This is useful, for example, if you like to avoid having to fill the same address details in every time you use a website – they are saved in a cookie and then can be automatically read in and re-filled next time you visit the page which stored them.
Cookies can also be used to store your browsing history and be shared across different websites so they can, for instance, display targeted advertising based on your history or shopping habits. Websites you didn’t really give permission to see your information are still using it. You might like the fact websites tune themselves to you and act in a customised way based on a profile or this may be a privacy issue for you as you don’t know what they are doing with your information. If the latter is the the case you should look in your web browser’s help system and find out how to limit cookie usage.
Secure information like credit card details are never stored in cookies.
