What are cookies?
How do they work
The site then ’knows’ that you have been there before, and in some cases, tailors what pops up on screen to take account of that fact. For instance, it can be helpful to vary content according to whether this is your first ever visit to a site – or your 71st.
Some cookies are more sophisticated. They might record how long you spend on each page on a site, what links you click, even your preferences for page layouts and colour schemes. They can also be used to store data on what is in your ‘shopping cart’, adding items as you click.
The possibilities are endless, and generally the role of cookies is beneficial, making your interaction with frequently-visited sites smoother – for no extra effort on your part. Without cookies, online shopping would be much harder.
There is nothing especially secret or exceptional about the information gathered by cookies, but you may just dislike the idea of your name being added to marketing lists, or your information being used to target you for special offers. That is your right, just as others are entitled to go along with the process.
When cookies first started to appear, there was controversy. Some people regarded them as inherently sneaky – your PC was being used (without warning) to store personal information about you, which could then be used to build a picture of your browsing habits.
What is the cookie law
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.
