Digital death and posthumous data: a glocal, relational perspective.

Persistent digital presence now routinely outlives biological death through memorialized profiles, algorithmic "memories," AI-mediated avatars, or biobank reanalysis. This perspective argues that decisions about such posthumous data-including postmortem genomic data-should be grounded in a glocally situated, relational view of personhood and practice, rather than in one-size-fits-all, individual-only rules. A small shared vocabulary is first proposed for use across disciplines: digital afterlife, digital immortality, posthumous lifespan, digital remains, and digital death. Digital death is treated phenomenologically as a lived, relational process: a hybrid online-offline experience in which dying, mourning, remembrance, and legacy unfold across digital and non-digital contexts. Second, it is argued that selves persist through relations, roles, and traces and that digital and genomic data amplify this relationality. Posthumous decisions, therefore, affect kin and communities and call for relational, kin-sensitive consent rather than static, individual authorizations. Third, a glocal lens is advanced: digital and data infrastructures always meet local death systems-institutions, rites, beliefs, and moral orders-that refract global capabilities into self-limiting "boundary solutions." To make this usable for genetics and allied fields, a brief action triage is outlined-focusing on stakes, relational radius, local death system, and time frame-and illustrate with a posthumous variant re-analysis/return-of-results scenario to help choose the least intrusive viable pathway. While approximate, such staged, glocally attuned practice can reduce foreseeable harm and support ethically coherent, clinically workable, and culturally credible uses of posthumous data.
