Sequencings
Read your own DNA file.
Without uploading it.
Every other service that interprets your raw DNA asks you to send it to them first. This one does not. Your file is read by your own browser, and nothing leaves this device.
Drop your raw DNA file here
23andMe, AncestryDNA, MyHeritage or Family Tree DNA. The unzipped .txt or .csv file.
This file is read by your own browser and is never uploaded. You do not have to take that on trust: open your browser’s network tab, load the file, and watch that nothing leaves.
Why that matters more than it used to
In 2025 23andMe entered bankruptcy with the genetic data of more than fifteen million people listed among its assets, two years after a breach affecting 6.9 million accounts. Genetic data is not a password. You cannot rotate it, and it implicates relatives who never consented to anything.
So this site is built the only way that makes the question moot: there is nowhere to send it. No account, no upload, no database.
What your file can and cannot tell you
It is a sample, not a genome
A consumer test reads about 650,000 chosen positions out of 3,100,000,000. Roughly two hundredths of one per cent, chosen for being common rather than for being medically important.
A clear result is not an all-clear
If a chip tests three variants in a gene with thousands of known harmful ones, not carrying those three tells you very little about that gene. Nobody selling you a report says this.
An alarming result is often wrong
A clinical laboratory re-tested 49 people’s raw consumer files and found 40 per cent of flagged variants were false positives, with 8 more misread by interpretation services.
Clever analysis cannot fix it
Imputation fills in untested positions statistically and works well for common ones. For the very rare variants that actually matter clinically, 0 to 1 per cent are recovered reliably. More analysis does not make thin data thick.
