A free, privacy-first DNA tool
Explore your genome
without giving it away.
Upload your raw data from 23andMe, AncestryDNA, MyHeritage, or Living DNA. Crick checks it against 108 peer-reviewed variant matches, shows you what they mean in plain English, and discards the file the moment it's done.
Named after Francis Crick, co-discoverer of the structure of DNA.
Built around four promises.
Privacy isn't a setting — it's the architecture.
Your file never touches our disk
Parsing happens entirely in a request handler. No /tmp file, no S3, no database row. The buffer is garbage-collected the moment matches are computed.
There is no account
Nothing to sign up for, nothing to log into, nothing to delete. Your results live in the URL itself — bookmark it and come back any time.
Open source, peer-reviewed
Every match cites peer-reviewed literature. The match library lives in YAML you can read on GitHub. The code is MIT-licensed.
Calibrated, not gamified
We classify findings as definite, strong, elevated, mild, informational, or trait — and we err on the side of lower severity when uncertain.
A glimpse of the library.
Every match is honest about effect size, references the literature, and acknowledges what it doesn't know.
