Transgender individuals in the United States face significant threats to interpersonal safety; however, there has as yet been relatively little research in the HCI and CSCW communities to document transgender individuals' experiences of technology-mediated safety and harm. In this study, we interviewed 12 transgender and non-binary individuals to understand how they find, create, and navigate safe spaces using technology. Managing safety was a universal concern for our transgender participants, and they experienced complex manifestations of harm through technology. We found that harmful experiences for trans users could arise as targeted or incidental affronts, as sourced from outsiders or insiders, and as directed against individuals or entire communities.. Notably, some violations implicated technology design, while others tapped broader social dynamics. Reading our findings through the notions of 'space" and 'place," we unpack challenges and opportunities for building safer futures with transfolk, other vulnerable users, and their allies.
