OpenGlobal Cookie Law Tool for Joomla
Simply install the plugin in the usual fashion and configure the plugin in the Plugin Manager with the link to your Privacy Policy page and enable the plugin.
You can optionally set a countdown timer to automatically accept the cookies and you can add javascript functions to be called when acceptance is given.
This plugin places a small discreet acceptance box in the top right hand corner of the page when a visitor first arrives at the website. The visitor can click "Yes" to accept cookies and continue through the website, or click "No" and are directed away from the website altogether.
If the visitor chooses to ignore the acceptance box but continues using the website, the tool uses implied consent. When the visitor clicks a link to another page on the website, this is considered acceptance. The visitor will not see the tool again (unless they clear their cookies or use another computer).
