Privacy in mobile applications is an important topic, especially when it concerns applications that gather and process health data. Using MyFitnessPal as an example eHealth app, we analyze how privacy-aware its user interface is, i.e. how well users are informed about privacy and how much control they have. We find several issues with the current interface and develop five design ideas that make the interface more privacy-aware. In a small pilot user study, we find that most of the design ideas seem to work well and enhance end users' understanding and awareness of privacy.
