Platform Features

Built for Precision and Privacy

Privacy Guard

Your raw DNA file is parsed entirely within your browser. Only the extracted variant strings (not the file itself) are transmitted to the server for analysis. Nothing is stored or logged.

Targeted VDR Analysis

Five well-studied VDR variants: FokI, BsmI, ApaI, TaqI, and Cdx2. Strand orientation is handled per variant so consumer-chip files are read correctly; any locus we can't read confidently is excluded, never guessed.

Plain-Language Report

Your report explains what your variants mean in everyday language, with an honest caveat about what genetics can and cannot tell you, and a practical next step. A "show the technical detail" expander reveals per-SNP rsIDs, genotype calls, and mechanism for anyone who wants the raw layer.

Process

Three Steps to Your Report

1

Upload

Drag and drop your raw .txt export from AncestryDNA or 23andMe into the secure upload zone. Both file formats are supported automatically.

2

Analyze

Your browser identifies the five target VDR variants. Only those small genotype strings are sent to the analysis engine, which applies strand handling per variant and calls each locus, or excludes it when the data doesn't fit the expected pattern.

3

Report

Get a short, plain language report: what variants you carry, an honest caveat about what genes can and can't tell you, and a practical 8-12 week experiment to find what works for you. Expand the technical detail layer if you want raw rsIDs and mechanism. Export to PDF in one click.
