We’re aware of the recent EU privacy directive and the related UK Cookie Law. As of now, the relevant authorities haven’t issued concrete guidance on the actions that are necessary to comply with the law. We’ll be watching as the situation develops and may make changes to our services in the future, if required.
For now – since sites hosted at WordPress.com do make use of cookies, you may like to flag this fact for visitors to your site. One way to do this is to add a text widget to your side bar and include a link to our privacy policy (which contains information on the cookies that we use).
