The Cookie Law is a piece of privacy legislation that requires websites to get consent from visitors to store or retrieve any information on a computer, smartphone or tablet.
It was designed to protect online privacy, by making consumers aware of how information about them is collected and used online, and give them a choice to allow it or not.
There are other technologies, like Flash and HTML5 Local Storage that do similar things, and these are also covered by the legislation, but as cookies are the most common technology in use, it has become known as the Cookie Law.
What are Cookies Anyway?
