Social networking buttons

We use social networking buttons to allow our users to share webpages or select them as favourites. These buttons connect to external social network websites which may record information about your internet activities, including on our website. Please read the terms of use and privacy policies of these websites to find out exactly how they use the information and how to eliminate or delete it.

External web services

Sometimes we use external web services to show content on our webpages, for example, to show images or videos. As is the case with social networking buttons, we cannot stop these websites or external domains from gathering information about the use of these incorporated contents.
