Mobile health (mhealth) apps are commonly used to keep track of our health, well-being, and everyday activities. They assist users with a variety of functions, including health tracking, understanding personal health issues, online doctor consultations, and achieving fitness goals. Although these apps provide easy access to healthcare, they do so by collecting, storing, and sharing a great deal of personal and confidential data about users. Personal information protection and privacy are major concerns when using mHealth apps.

This paper identifies the privacy threats and security features of mHealth applications, how they are assessed, and how the users perceive the privacy of mHealth applications, based on a literature review. According to the findings, providing a single mechanism for categorizing mHealth applications in terms of security and privacy is essential and beneficial.
