# GEDminer

> GEDminer is a free, privacy-first, browser-based tool for analysing GEDCOM
> family-tree files. Parsing and analysis run in the user's browser and the
> GEDCOM file itself is not uploaded for analysis. The only data sent for the
> optional community comparison is an anonymous, aggregate Tree Health summary
> (four percentages, individual and family counts, and a one-way tree
> fingerprint computed locally from hashed identity signals); signed-in users
> may additionally choose to save parsed tree data to their account.
>
> It surfaces demographics, migration patterns, kinship relationships, data-quality issues, census gaps, and prioritised
> research suggestions for genealogists.
