Your raw DNA file never leaves your browser, here’s the actual mechanism

“We take your privacy seriously” is a promise. Keeping your raw file on your device is an architecture. The difference is everything.

When you drop your raw data file into Verinome, it is read into your browser’s memory and parsed there, on your machine, by code already downloaded to your device. That file is about 24MB and holds 600,000+ markers, and it never uploads. To build your report, your browser reads only the specific marker positions our database scores, about 200 of them, a few kilobytes of readouts with no name and no file attached, and sends just those to our server. The server matches them against our evidence database, returns your findings, and stores nothing.

You don’t have to take our word for it. Open your browser’s Network tab while you analyze a file and watch your 24MB file stay put: it is never uploaded. When you run the report you will see exactly one small request to our server, carrying about 200 marker readouts, a few kilobytes, no file and no name. That request returns your findings and leaves nothing behind. Our privacy page spells out precisely what that request does and does not contain.

What we do see

To build your report, our server briefly receives about 200 marker readouts, holds them only long enough to return your findings, and stores none of them; they are never linked to you, never sold, never used for marketing. To take a one-time payment, Stripe collects your email and card details on its own secure form, never your raw file. We keep a minimal order record, and today, no analytics at all; if that ever changes it will be cookieless, aggregate, and self-hosted. That’s the entire list, and your raw DNA file with its 600,000+ markers isn’t on it.

See it for yourself: read exactly what leaves your browser, or watch your file not upload.
