This document discusses the information practices of humanitarian organizations serving undocumented populations and proposes a conceptualization of "digital sanctuary." It provides context on global migration trends and outlines current sanctuary models that provide safe spaces for those facing threats like detention. While humanitarian organizations rely on privacy-protecting methods, they lack data privacy training. A digital sanctuary framework is proposed, emphasizing collecting minimal data and relying less on technology. This would better protect vulnerable populations' information while supporting them through exposure and voice.
