What disclaimers should be on the site?

Question

Law in IT

Often I began to see that on the sites at the bottom there is a mention that "we use cookies to collect information of a technical nature and process the IP address of your location. By continuing to use this site, you consent to the use of cookies."

Look at the posts on Habré about the GDPR - General Data Protection Regulation (Regulation (EU) 2016/679), which comes into force on May 25, 2018. Relevant for sites and shops that work with personal data of EU citizens.
