01 / What it does

A DNA report that never leaves your browser.

  • 01

    Ancestry and lineage

    Ancestry composition plus maternal and paternal haplogroups, computed in client-side JavaScript.

  • 02

    Traits and a genome explorer

    Traits, carrier variants and a searchable explorer over the raw file you already downloaded.

  • 03

    Your file stays yours

    Parsing and matching run on your device. Close the tab and the only copy is the one you already had.

02 / The record

What it can prove, and where it stops.

Proven safeguard
The genome file is parsed on your device and never uploaded.
Limits
Not a medical device, not a diagnostic test and not medical advice.
