In the European Union, the Directive 2009/136 / EC the Personal data protection when visiting websites. The EU Cookie Directive, which was passed in 2009, was supposed to be implemented by all member states by 2011 at the latest - but this did not happen.
The Cookie Directive essentially stipulates that visitors to a website are informed about the use of cookies in an easily understandable form and must consent to their storage. According to the directive, cookies may only be used set without asking will if they technically necessary – for example, to implement a service requested by the user. These include Session cookies to store the language setting, log-in data and shopping cart or Flash cookies to play media content.
However, website operators require user consent to use most cookies. This applies to all cookies that are not technically necessary for the functioning of the website. In particular, advertising cookies that are necessary for the Retargeting used, but also analysis and social media cookies are included. However, the EU directive does not specify exactly how the requirements mentioned are to be implemented. There is uncertainty, especially with regard to the consent of website visitors.
