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.
Why Cookie Law?
If you own a website, you will need to make sure it complies with the law, and this usually means making some changes.
If you don't comply you risk enforcement action from regulators, which in the IT means The Information Commissioners' Office (ICO). In exceptional cases this can mean a fine.
