What are cookies?
A cookie is a small file of letters and numbers that is downloaded on to your computer when you visit a website. Cookies are used by many websites and can do a number of things eg remembering your preferences, recording what you have put in your shopping basket, and counting the number of people looking at a website.
The rules on cookies are covered by the Privacy and Electronic Communications Regulations. The Regulations also cover similar technologies for storing information, eg Flash cookies. The Regulations were revised in 2012, and the ICO is responsible for enforcing these new rules.
What do the new rules mean?
How will these new rules impact on me when I use the internet?
As organisations start to comply with these rules you are likely to start to see more information about cookies on sites and be given more choices about these cookies. This might include, for example, being asked to agree to a cookie being used for a particular service, such as remembering your preferences on a site.
Organisations will need to decide on the best way to provide clear information about cookies and to give people using their websites the right choices. They will also want to make sure that these changes do not adversely affect the experience of people using the internet. This should ensure they find a solution which meets the requirements in a way that works well for their site and meets the needs of people using it.
How can I control my cookies?
You can use your web browser eg Internet Explorer to:
- delete all cookies
- block all cookies
- allow all cookies
- block third-party cookies
- clear all cookies when you close the browser
- open a private browsing session
- install add-ons and plug-ins to extend broswer functionality
- A number of websites provide detailed information on cookies, including AllAboutCookies.org and AllAbout Cookies.org.uk .
- The Internet Advertising Bureau website Your Online Choices allows you to install opt-out cookies across different advertising networks.
- Google has developed a browser add-on to allow users to opt-out of Google Analytics across all websites which use this popular analytics product.
- New technologies such as Mozillas Do Not Track allow you to tell websites not to track you.
- Internet Explorer has a feature called Tracking Protection Lists which allows you to import a list of websites you want to block.
What should I do if Im concerned about cookies?
In May 2011 we gave organisations 12 months to work towards complying with the new rules, and we expect website owners to have looked at the cookies they use and where necessary put in place steps to get your consent.
Report your cookie concerns
Were asking people to report your cookie concerns . This will help us find out how organisations are complying with the new cookie law. Rather than reply to each person individually, we will publish information about numbers and types of concerns reported, and let you know what were doing about them.
