DNA Layer and TellMeGen: your data, handled two ways
DNA Layer never stores your raw DNA file. Here's how that compares to TellMeGen's own GDPR-based privacy policies, and what it means for your existing TellMeGen raw data file.
Last verified 18 August 2026How DNA Layer handles your data
Your raw DNA file is read locally in your browser. DNA Layer does not store your original raw DNA file — only the derived findings needed to show your health layer are kept, DNA Layer never sells genetic data, and you can delete everything from your account at any time.
TellMeGen’s own stated privacy policies
TellMeGen is based in the EU and states it complies with the GDPR, processing data based on informed consent. TellMeGen’s own materials describe the user as, in their words, “above all, the owner of their genome” — and state that genetic data is not rented or sold to third parties, including insurers or pharmaceutical companies, and is not shared with third parties without your explicit authorisation. Under GDPR, you also have the right to access, rectify, delete, port, object to, and limit the processing of your data. TellMeGen states it applies encryption to data both in transit and at rest, alongside access controls.
If you already have a TellMeGen file
None of the above changes what you can already do with a TellMeGen raw data file you have already downloaded. DNA Layer reads that same file — the one from your existing TellMeGen account — to build your personalised health layer. You do not need a new test.
Frequently asked questions
Do I need to take a new DNA test?
No. DNA Layer is built for the raw data file from a test you have already taken. If you have never tested, any of the supported consumer providers will do.
What happens to my genetic data?
Your file is read locally in your browser. We keep the minimum needed to show your layer, we never sell genetic data, and you can delete everything from your vault whenever you want.
