FreeStyle Libre data, in your own stack.
Abbott publishes no developer API for FreeStyle Libre, so there's no Libre connector. Its readings still arrive when the Libre app writes them to Health Connect on Android or Apple Health on iPhone.
- Source
- Continuous glucose monitors
- How the data arrives

How it works.
- 01
FreeStyle Libre writes to Health Connect or Apple Health
On the phone, the FreeStyle Libre app shares its data with Health Connect or Apple Health.
- 02
Your app uploads it
Your app reads Health Connect or Apple Health and uploads it, as on the Health Connect or Apple Health page. Each record keeps FreeStyle Libre as its source.
- 03
You read one model
The records land in the same model as every other source, over REST, MCP and FHIR R4.
Before you start.
- Abbott publishes no developer API, and LibreView integrations are by agreement only.
- Open Health Sync won't use the unofficial LibreLinkUp app API.
- Readings that arrive through Health Connect keep the Libre app as their source.
Where to start.
FreeStyle Libre has no connector of its own: set up the source its data goes through.

Do I need anything from FreeStyle Libre?

Where does the data go?
Only to the server you run. Open Health Sync is self-hosted software, not a service: no account with us and no call home. Each user can be deleted with one call, raw files included.
