UK Cookie Consent is a WordPress plugin by catapult that helps compliance with the UK interpretation of the EU regulations regarding usage of website cookies.
UK Cookie Consent Plugin for WordPress
A user to your site is presented with a clear yet unobtrusive notification that the site is using cookies and may then acknowledge and dismiss the notification or click to find out more. The plug-in automatically creates a new page with pre-populated information on cookies and how to disable them, which you may further edit if you wish.
The plug-in does not disable cookies on your site or prevent the user from continuing to browse the site – it comes with standard wording on what cookies are and advice on how to disable them in the browser. The plug-in follows the notion of “implied consent” as described by the UK’s Information Commissioner and makes the assumption that most users who choose not to accept cookies will do so for all websites.
