Terms, disclaimer and privacy

Last updated 1 October 2026

The short version

  • DNA Signpost is run by one independent genetic genealogist. Articles and guides are personal opinion and analysis, offered free and in good faith.
  • It is not affiliated with, endorsed by or paid by any DNA testing company.
  • Tool results are estimates based on stated assumptions and the data available. They can be wrong. Check anything important.
  • Genealogy only. Nothing here is medical, health, legal or other professional advice.
  • Your raw DNA files are read in your browser and are never uploaded.
  • You use the site at your own risk.

Opinions and analysis

Articles reflect the author's own research and views at the date shown on each one. Genetic genealogy moves quickly: testing companies change their algorithms, reference populations and haplogroup trees are revised, and new evidence turns up. An older article may no longer be current. Where an article relies on someone else's data or research, it says so and links to the source.

No affiliation

AncestryDNA, 23andMe, MyHeritage, FamilyTreeDNA, GEDmatch and other company and product names mentioned on this site are trademarks of their respective owners. They are used only to identify the services being discussed. DNA Signpost is not affiliated with, sponsored by or endorsed by any of them.

The Y-DNA Consistency Checker looks up FamilyTreeDNA's publicly available haplogroup tree. That data belongs to FamilyTreeDNA, and the tool links to their site for the full picture.

What the tools can and can't do

Each tool works from what you give it and from published reference data, using the assumptions it states. Consumer DNA tests only read a sample of positions, so some questions can't be settled from them; the tools say so rather than guess. Results are not a substitute for a more detailed test where one is needed (for example a full mtDNA sequence or a dedicated Y-DNA test).

Do not rely on anything on this site as proof of identity, parentage or relationship for legal, immigration, inheritance or similar purposes. Those need an accredited laboratory.

Not medical or professional advice

This site covers genealogy and ancestry only. It does not interpret health, medical or trait information and nothing on it should be read that way. Nothing here is legal, financial or other professional advice.

No warranty, and limits on responsibility

The site, its tools and its content are provided free and "as is", without any promise that they are accurate, complete, current or available. As far as the law allows, DNA Signpost and its author accept no responsibility for any loss, cost or decision arising from use of the site or reliance on its content. Nothing in these terms limits any liability that cannot legally be limited.

Links to other sites

Links to other websites are provided for convenience. Those sites are run by others, who are responsible for their content, terms and privacy practices.
