The purpose of the “GDPR in Your Pocket” mobile application, developed and validated under the REC Programme of the European Union, is to introduce GDPR to citizens and SMEs in an easy-to-use and easy-to-understand way, and to give them practical knowledge and advice with respect to their rights and obligations under the EU data protection law. Under Work Package 3 project activities, the application content was supplemented with relevant legislation and case law in the field of personal data protection and currently includes a rich collection of legal documents of the European Union and four EU Member States – Bulgaria, Italy, Germany and France. The user interface, which initially was made available in English, Italian and Bulgarian, has also been translated into German and French. This upgrade of the tool has made it possible to reach more than 42% of the EU population in their mother language. In addition, “GDPR in your pocket” was developed as a hybrid application that can be installed on both iOS and Android devices and Windows 10/11 devices.
