GDPR (General Data Protection Regulation) is a Regulation prepared by the European Parliament, the Council of the European Union, and the European Commission. It replaced the 1995 European Data Protection Directive (95/46EC). The idea behind GDPR is to provide individuals with full control over their personal data, as well as to strengthen and unify rules governing data collection from individuals within the European Union.
GDPR entered into force on 25 May 2018. One of the most important obligations under the law is that companies must now obtain the consent of data subjects in order to store and process their personal data.
