The use of mobile devices and wearables in healthcare is an important trend. To increase the motivation for regular use of such mHealth applications gamification elements have a huge potential. On the other hand for the integration of gamification concepts in mHealth applications personal health related data and usage data needs to be processed. Based on a categorization of gamification elements and examples for mHealth applications an overview about the aim of the use of gamification is given. It is analysed whether the processing of personal data is needed and if privacy is considered in the examples for the realization of gamification elements. Based on this analysis approaches for addressing privacy risks in gamification in mHealth are proposed.
