Websites today normally offer some level of interaction – whether it’s sending and receiving messages, buying goods or choosing how you wish to view the site. To manage this, small text files called cookies are stored on your computer.
For more information on cookies and how you can manage your privacy settings, read through our FAQs below
Are cookies viruses?
No. Cookies are not viruses, Trojans, spy ware, or worms or any other kind of malware.
Are cookies programs?
No. Cookies are not programs. They can’t install things you don’t want on your computer.
Can cookies see what’s on my computer?
No, cookies can’t see what is on your computer. Nor can they collect any other information from your computer, nor snoop on your files.
Can the cookies I’ve got be seen by other people?
No. A cookie can only be read by the site that gave you the cookie in the first place. And of course you can see your own cookies, as described later.
What is in a cookie?
A cookie contains seven main pieces of information:
Domain The domain of the website that set the cookie. A cookie can ONLY be ready by the site that set it.
Name The name of the cookie
Value The identifying information the cookie is carrying. This is normally an encrypted string of letters and numbers, that is only meaningful the website that set the cookie.
Expiry How long the cookie lasts for. If this is not set, the cookie will disappear when you close your browser (session cookies). Otherwise it will delete itself on the date set in the expiry field.
Path This is not always used, but can be set so that the cookie is only sent when the user is in a particular part of the website. For example if the domain is set to acme.com, and the path is set to /accounts, the cookie will only be used when the user is in the acme.com/accounts part of the site.
Secure This attribute can be used to tell the browser to only use the cookie when it is using a secure or encrypted connection.
Can I control the cookies I get?
How can I see and manage my cookies in my browser?
Virtually all modern browsers allow you to see what cookies you’ve got, and to delete them individually or delete all of them.
Many browsers can also be set up to ask consent for each individual cookie before it is set. This gives you very fine control over what cookies you get, but it can slow down your browsing experience if you have to check each and every cookie.
Most browsers also give you the right to block third party cookies. Most of these third party cookies will be the behavioural advertising cookies. Therefore blocking 3rd party cookies is effectively opting out of most behavioural advertising.
Some browsers let you block cookies from particular sites. So for example if you are happy to get cookies from a site you trust, but you don’t want to get cookies from a site you don’t particularly trust, you can set up your browser to black list the site you don’t trust and refuse any cookies it tries to give you.
Most browsers will let you delete all cookies when you close your browser. You should be aware that any preferences including any opt outs you have set will be lost if you do this.
Finally, you can tell your browser to block all cookies from being set. You should be aware that if you do choose this option many sites will not work as smoothly as you are used to, and some functionality that is reliant on cookies to enable services you want to use will not work at all.
