Privacy & data handling

Telos is a private, friends-and-family tool. This notice explains how your genome data is handled — how your uploaded file is used to build your report, and what is never shared without your say-so.

Educational, friends-and-family positioning

This is an educational tool for friends and family. It explains your genome and suggests what is worth discussing, but it is not a medical device and not a substitute for professional care — a diagnosis and any treatment or medication decisions are made with a clinician.

Reports are confidence-bounded: they call strong findings clearly and flag the tentative ones, and point you toward the right conversation with a professional.

How your raw data is handled

You upload your DNA data — including raw files from services like sequencing.com. Telos uses that file only to run the analysis that builds your report, on infrastructure the operator controls. It is handled privately and is never sold or shared with advertisers.

Your uploaded file is retained for 30 days and then deleted automatically. We keep it that long for one reason: so you can run additional analyses over the same file without re-uploading — for example the genome-wide ancestry map, which is computed on demand and takes several hours. You can delete your uploaded file yourself at any time, from your report; that deletion is permanent and unrecoverable, and afterward any new analysis simply requires uploading the file again.

The readable report, data summary, and generated prompt are produced from the analysis, so raw genomic data is never present in the artifacts you read, download, or share.

What is and is not sent to external LLMs

The tool makes no calls to any external LLM on your behalf. It only generates a prompt for you to copy.

If you choose to paste that prompt into ChatGPT, Claude, Gemini, or another service, that is your decision and happens outside this tool.

  • Sent (only if you paste it): the descriptive report text and the structured data summary, including confidence tiers and caveats.
  • Never sent: raw VCF or genotype files, real names, contact details, secrets, or file paths.

Raw data is kept out of logs, analytics, errors, exports, and prompts

Your raw file is used to build your report and is otherwise kept out of every downstream surface. It is not written to application logs, analytics, or error reports, and it is not embedded in exports or generated prompts.

  • Logs — no raw genomic data is logged.
  • Analytics — no raw genomic data is sent to analytics.
  • Error reports — no raw genomic data is captured in errors.
  • Exports — export packages contain only the descriptive report and its artifacts.
  • Prompts — generated prompts contain only descriptive content, never raw data.
