To become part of our everyday social environment, robots will need to be developed in a way to gain an appropriate level of trust of humans, both users and bystanders. One important aspect influencing trust is the handling of privacy. In this paper, we explore privacy challenges of social robots when acting in the role of mediators in human-human interactions within domestic assistance scenarios. We approach this topic by reviewing privacy research on related technologies that already exist in many households, namely smart home and smart speaker devices. We extract common user concerns and requirements with respect to general data sharing based on their experience with using these technologies and evaluate which of these will be relevant for a robotic mediator design. We also discuss research on privacy implications of shared devices and telepresence robots, which extend the use cases to possible data sharing between humans. Finally, we point out mediator-specific privacy challenges in the realm of social privacy to highlight open research questions that should be addressed when targeting a deployment of robotic mediators.
