Privacy
The best way to protect your data is not to collect it. This page lists exactly what we keep and what we don't.
What we keep
- The sample code you receive when you submit.
- The test results and chromatogram.
- Your notification address, only if you gave us one. We delete it after we send your result.
- Overall counts for reporting, such as samples per month and compounds tested.
What we never ask for
- Your legal name
- Your home address
- Your date of birth
- Your prescriber or pharmacy
- Any medical history
Shipping labels
- You don't have to include a return address. If you do, we keep it only until the sample arrives.
- We don't scan, photograph or store envelopes.
- Labels are shredded within 7 days of arrival.
Who can access what
- Two volunteers have access to the results system.
- The lab only ever sees the sample code, never contact details.
- Backups are encrypted and replaced every 90 days.
- No third-party analytics, no trackers, and no cookies beyond what the site needs to work.
Legal requests
- If we're legally required to share information, we can only share what we have.
- We deliberately keep very little.
- We publish a warrant canary every quarter.
