How to analyze your 23andMe raw DNA data
When you test with 23andMe, the lab measures hundreds of thousands of positions in your DNA — and lets you download the results as a raw data file. That file is yours, and 23andMe's own reports only use a small part of it. Read with the right tool, the same file says much more: how published research links your variants to caffeine metabolism, lactose tolerance, sleep timing and dozens of other everyday traits.
This guide shows how to download your raw data from 23andMe and analyze it with DNA Is Mine, an app that reads the file entirely on your iPhone, iPad or Mac. Nothing is uploaded — there is no DNA server and no account. If privacy is your main concern, start with how private analysis works.
What is in a 23andMe raw data file?
The export is a plain-text table with one measured marker per line: a marker ID (an rsID such as rs762551), the chromosome, the position, and your genotype — the pair of DNA letters found there. Lines starting with # are comments describing the file, including the reference genome build it uses. 23andMe usually delivers it as a ZIP containing a single .txt file.
It is genotyping data, not a full genome sequence: the test measures a selected set of positions known to vary between people. That is plenty for research-based findings, but it is worth knowing what the file is — the raw DNA data guide explains the difference in plain terms.
How to download your raw data from 23andMe
- Sign in to your 23andMe account and open Settings.
- Find the 23andMe Data section and choose the raw data download.
- Confirm your identity — 23andMe asks for your password and date of birth before it prepares the file.
- 23andMe emails you a download link. Save the ZIP file somewhere you can find it again.
You do not need to unzip anything: DNA Is Mine opens ZIP and gzip containers directly. And treat the file like a medical record — it is effectively a partial blueprint of you, so store it somewhere private rather than emailing it around.
How to open the file in DNA Is Mine
- Download DNA Is Mine free from the App Store (iPhone, iPad or Mac).
- Import the ZIP or text file — on a Mac you can drop it onto the app; on iPhone and iPad you pick it from Files or share it from where you saved it.
- The format is detected automatically and the analysis runs on your device. You get a full overview of your file first, then your findings.
No file handy yet? The app includes a fictional sample genome, so you can explore a complete report before importing anything. DNA Is Mine is a raw DNA data reader built for exactly this: files stay on the device that opens them.
What you can learn from it
DNA Is Mine checks your markers against a knowledge base of 106 findings in five areas of everyday life — traits (33), nutrition (32), sleep (10), fitness (5) and metabolism (26) — drawn from 138 published papers. From a typical 23andMe file you can read, for example, caffeine metabolism (CYP1A2, rs762551), caffeine sensitivity (ADORA2A, rs5751876), lactose tolerance (MCM6/LCT, rs4988235) and eye color (HERC2, rs12913832).
Every finding shows the gene, the variant, your genotype, a plain-language explanation, an evidence-strength rating and the studies behind it. The free download includes your full data overview, 13 complete findings and 3 Ask My DNA questions; Pro unlocks all 106 findings and unlimited questions, as a monthly or annual subscription or a one-time lifetime unlock, all handled by Apple.
What DNA Is Mine does not do
- No ancestry percentages, ethnicity estimates or relative matching — 23andMe already does those; this app reads research findings instead.
- No disease diagnosis or risk prediction. Findings summarize published associations; an association is not a diagnosis.
- No uploads, no account, no ads and no cross-app tracking — see the privacy guide for exactly what that means.
- Not every file works: VCF, BAM, FASTQ and PDF reports are not supported, and neither are password-protected archives.
Format samples checked: 23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA Family Finder and Living DNA autosomal exports. Genebox exports have also been verified with an actual file. WeGene exports still need verification; not every vendor version is covered.
Import UTF-8 genotype text (.txt, .csv, .tsv), ZIP or gzip (.gz). Each row needs a marker ID, chromosome, position and genotype (or two allele columns). Password-protected archives, VCF, BAM, FASTQ and PDF reports are not supported. Available findings depend on the markers in your file.
Free download. No account. Your file is analyzed on your device, never uploaded.
Analyze your 23andMe dataQuestions
Is it free to analyze my 23andMe raw data?
The app is free to download, and the free version includes a full data overview, 13 complete findings and 3 Ask My DNA questions. Pro unlocks every finding and unlimited questions, as a monthly or annual subscription or a one-time lifetime unlock, all processed by Apple. Your exact local price is shown in the App Store.
Does DNA Is Mine upload my 23andMe file?
No. The file is parsed, matched and explained on your device, and the original file is not copied or kept. The app saves only summary statistics about the file and the genotypes of the markers your report uses. It counts a small number of anonymous usage events — never DNA, genotypes, findings or questions.
Which 23andMe files are supported?
DNA Is Mine imports UTF-8 genotype text files (.txt, .csv, .tsv), including ZIP and gzip containers, and 23andMe export samples have been checked against it. Compatibility depends on the export's layout, so not every vendor version is guaranteed; if your file will not import, contact support@dnaismine.com.
Can DNA Is Mine estimate my ancestry or find relatives?
No. It does not calculate ancestry percentages or match you with relatives. It explains research findings about traits, nutrition, sleep, fitness and metabolism found in the file you already have.
Is this medical advice?
No. DNA Is Mine is educational software. Findings describe what published studies associate with a genotype; they do not diagnose, treat or predict disease. For health decisions, talk to a qualified professional.
