title = "Privacy apps for smartphones: An assessment of users{\textquoteright} preferences and limitations",
abstract = "Smartphones are becoming our most trusted computing devices for storing and dealing with highly sensitive information which makes smartphones an essential platform to take under control utilizing privacy-preserving applications (apps). There exists a variety of privacy preserving apps on the mobile platform which claims to offer a potential way for people to protect data on their mobile phone. However, there has been no systematic study of these apps and what features and functionalities they offer or what may contribute to their under-utilization by mobile users. In this study, we analyzed the general functionalities of iOS privacy preserving apps by examining features designed to support user engagement and their privacy preserving functionalities. In addition, we examined user experiences, through a thematic analysis of publicly available user reviews of sampled apps. Our findings provide insight from users{\textquoteright} reviews and their usability challenges in use of these privacy apps as well as the fundamental privacy features they are seeking. We believe these findings will guide privacy application developers in building appropriate functionalities that is more realistic and relevant to mobile users{\textquoteright} daily life. In addition, this study provides the preliminary steps towards a comprehensive and actionable privacy tools/architecture for mobile phones that is human centered.",
