Cookies may have been explained to you as evil and intrusive spying tools tracking your every move on the Internet. They are simple text files mainly designed to make your life easier.
Cookies are NOT programs; they do not do anything at all. They are simple text files that can only be read by the website that put them there and you on your local PC. Primary, they are used to store your user id and name for a particular site, also, sometimes the date and time you last visited, and how many times you have visited.
Some cookies are a bit more sophisticated. They may record how long you spend on pages on a site, what links you clicked and your choices for layouts and colour schemes. They are often used to store the products in your “shopping cart” adding and removing items as you select them. The uses of cookies are extensive; their role is usually beneficial, making your interaction with favourite sites smoother with less input on your part. Without cookies, online shopping would be much more challenging.
There is no great secret or anything exceptional about the information gathered by cookies; you can view the contents of those on your PC in Notepad.
But, you may just dislike the idea of companies adding your name to their marketing lists, or your information being used to target you with special offers, but they can do that anyway if you shop with them both online and in the high street stores. If you do not want this, that is your right, just as others are entitled to go along with the process.
