This document describes a design challenge to create a system for managing data flows and access within computational social science studies in a privacy-aware manner. The system should support multiple studies conducted by different researchers while reusing common functions like user management, informed consent processes, and data access controls. It should allow multiple users in different studies to continuously view collected data and manage their consent and authorizations. Privacy-aware approaches are needed as sensitive personal data is increasingly collected at scale, but current solutions are minimal; the goal is a simple yet effective system like Funf for data collection from phones.
