Different service providers on the Web formulate their privacy policies based on their business scope. However, the progress of HTML5 has largely facilitated the acquisition of user-relevant data via Web browsers (e.g. location, device battery level, network information). Users can give their consent on the use of this sensitive information, but should have the right to express their privacy preferences, so that Web applications can adapt themselves accordingly. In this work, we address the above by specifying a privacy preferences language for users tailored to HTML5 Web applications employing the eXtensible Access Control Markup Language, whereas we introduce a mechanism that adapts the Web application considering these user preferences. Our approach does not rely on complex structures allowing the easy specification of the policies and the context of its use utilizing a browser installed extension mechanism. We describe the process followed for the creation of the privacy preferences, the process of application adaptation and the benefits this approach provides to end-users via a demonstration and evaluation of the use of the extension.
