Privacy-First Indexing: Why Local Storage Protects Genetic Data
Genetic genealogy research involves some of the most sensitive personal data imaginable: DNA profiles, family relationships, medical predispositions, and the identities of living individuals who may not know they are being researched.

Local-first storage keeps genetic data where it belongs: on the researcher's own machine, under the researcher's sole control.
