Abstract: The massive usage of mobile phones connected to the internet over the last years has changed the business model of all sort of companies and services around the globe. By turning on your mobile phone and connecting it to the internet, it is possible to reach a countless amount of information and the products are literally at your fingertips. In view of this new reality, the concept of a mobile app that aggregates services (i.e., super apps) seems to be the next game-changer for the mobile apps industry, and the challenges related to security and privacy are key aspects for keeping user data safe. In this paper, we propose a complete auditable decentralised super app architecture in order to prevent the risks of a centralised ownership, to provide a full log of shared data and to control data access between the stakeholders. An environment containing all the proposed implementations were built and successfully tested to prove the feasibility of deploying such architecture in real world applications.
