The new UK rules apply to all websites hosted in Europe and websites hosted elsewhere if they target UK residents. U.S. websites that market their sites to UK residents or that have a large number of UK users may be subject to the new rules and be required to comply.
The AddThis toolset does use cookies to enable some aspects of the service, such as menu personalization and content analytics. Though the legal requirements don’t specify any specific steps required over the course of the next year, we’ve already been evaluating different ways to make sure that if your website falls under the jurisdiction of the UK regulations, we can help you be fully compliant while using AddThis. Expect updates via this blog and our support forums as we roll out configuration features to support the opt-in capabilities, and if you have any questions at all, please don’t hesitate to contact us.
