Currently, it appears as though no conversation or financial transaction is private or secure. Recent technological advancements have fundamentally altered the concept of privacy, increased the value of collected data, accelerated data collection efforts, and sparked debates about the role of third parties, the degree of user involvement in privacy settings, and the commercialisation of user data. Nevertheless, consumers are often uninformed of the hazards and potential misuse of private data by internet marketers when they decide to share it or to talk online. Regarding mobile apps, the exposure of user data is complemented with rich data generated on the device, user location, and contact list – as well as other data that continuously monitor users' activities. It's nearly impossible to use a mobile messaging app without exposing our most private messages across public networks and entrusting them to the servers of the firms who operate them. From there, our texts and emails, as well as images and video recordings, are subjected to sophisticated algorithms designed solely to generate profit for businesses.
