Cookies are small text files that web sites can send to your computer. A cookie can be thought of as an internet user's identification card, which tells a web site when the user has returned. Cookies are not computer programs, and can't read other information saved on your hard drive. They cannot be used to disseminate viruses, or get a user's e-mail address etc. They only contain and transfer to the web site as much information as the users themselves have disclosed to that web site.
The Privacy and Electronic Communications (EC Directive) Regulations 2003 ("the Directive"), recognises that cookies are a "legitimate and useful tool" for many activities, including verifying the identity of web site users. The Directive makes it compulsory for web sites to inform users if cookies are being used, and to provide some information on how cookies are used. Please note that users can set their computers to reject cookies and you can find the instructions on how to do this, and more information about cookies, at allaboutcookies.org. However, you should be aware that the Store Excel website (in common with most other web sites) may not work correctly without cookies being fully enabled.
