Bloodwork Ledger stores your lab results only in the app's storage on your own phone or computer. There are no accounts, and we keep no copy of your results on any server.
When you connect a health system, you sign in on that health system's own page. Bloodwork Ledger receives read-only access to your lab results and basic patient record, and the results go directly from the health system to your device. We don't receive or store your portal password or your results. Access is used once to download your results and is not kept.
When you ask the app to read a PDF, photo or pasted text, that report is sent once to Anthropic's Claude service to extract the values, and the extracted results are returned to your device. Our server passes the report through without storing or logging it. Files from a portal's "Download my record" option are read on your device and are never sent anywhere.
No advertising, no tracking, no analytics, and no selling or sharing of health information.
Because results live only on your device, deleting the app or clearing its data deletes them. Use "Save a backup" to keep a copy you control.
Bloodwork Ledger keeps a record of your results. Talk to your doctor about what they mean.
Questions: contact the person who shared the app with you.
