However, the majority of the applications are lacking in security and compliance when dealing with information which result in severe problems. This article presents the key points of privacy, data protection, and the GDPR about mobile applications and pinpoints the most usual weaknesses. An informed guide with information about privacy-preserving techniques and their implementation in application development has been created. This paper will complement other researches about privacy and data protection in mobile applications and could raise concerns for users, application developers and researchers.
