Privacy Policy

Last updated: June 17, 2026

Overview

Blood Labs is built on a simple principle: your health data belongs to you. This policy explains what data the app handles, where it lives, and the choices you have. The short version — your lab results stay on your device, encrypted, and we never see them.

Data we collect

The app stores the lab results you import: marker names, values, units, reference ranges, test dates, and lab names. You can optionally add profile details such as a name, color, date of birth, and sex to improve reference-range accuracy. We do not collect your real identity, location, or contacts.

How your data is stored

All results are kept in encrypted local storage on your device. Encryption keys are protected by your device’s secure enclave. Nothing is uploaded to our servers — there is no Blood Labs cloud account, and the app works fully offline.

What we never do

  • No AI models are trained on your health data.
  • No data is sold, shared, or rented to third parties.
  • No advertising and no cross-app tracking.
  • No analytics tied to your lab values.

Photos and lab reports

When you snap a photo of a lab report, recognition happens on your device. The original image and the extracted markers are stored locally and can be deleted at any time. Images are never transmitted to external services.

Family profiles

Profiles you create for family members live only on your device. Each profile’s results are stored separately and protected by the same encryption. You are responsible for obtaining consent from the people whose results you manage.

Your rights

Because your data never leaves your device, you are always in control. You can export your records, correct any value, or permanently erase all data by deleting a profile or uninstalling the app. There is no copy on our side to request or remove.
