As robots become more and more common in human environments, ensuring privacy-aware robot navigation becomes essential. Various methods have been proposed to address privacy, such as desensitizing, but they do not enable a fine grained contextual adaptation to a specific deployment site. Our ongoing work explores methods that enable service owners of office robots to fine tune and dynamically adjust robot navigation behavior to respect contextual privacy. We propose an end-user interface that integrates a multimodal Large Language Model (LLM), allowing users to define, refine, and enforce predefined privacy rules. In this paper we define generic office privacy rules and the reasoning required to make them contextual. These mechanisms enable robots to anticipate privacy-sensitive situations using time, location, service type, and human presence as contextual factors.
