Frequently Asked Questions
What do I get for $109?
You get the full LabsLedger app — forever. It's yours to keep, no subscription required. The app runs entirely on your Mac with all features unlocked: PDF import with OCR*, 900+ biomarker tracking, trend charts, doctor reports, session comparison, data export, and more.
Is this a subscription?
No. LabsLedger is a one-time purchase. You pay $109 and you own the app — with free updates for life covering all v1.x releases. No recurring fees, no renewal needed.
Can I use it on multiple Macs?
Yes! Your license works on up to 2 Macs that you own.
Is there a student or educator discount?
Yes! Contact us at support@sierranovalabs.com for academic pricing.
What is your refund policy?
We offer a 30-day money-back guarantee — no questions asked. If LabsLedger isn't right for you, just email us for a full refund.
Where is my data stored?
All data is stored locally on your Mac in a sandboxed database. LabsLedger never transmits your health data anywhere. You can optionally use iCloud for syncing between your own devices. We never access or transmit your data — we literally can't.
Is this a cloud app?
No. LabsLedger is a native macOS application that runs entirely on your Mac. There are no cloud servers, no accounts to create, and no internet required (except for one-time license activation). Your data lives on your device, not in someone else's cloud.
Which lab providers are supported?
You can import a PDF from any lab provider. We use Apple's on-device Vision OCR — not cloud-based AI — so your lab PDFs never leave your Mac. Parsing is optimized for Quest Diagnostics, LabCorp, and Health Gorilla. Results vary by format and PDF quality — the split-pane review lets you verify and correct extracted values before saving, and manual entry is always available.
