Where Does LibreLink Store Glucose Data?
LibreLink FreeStyle sensor scans on the account with LibreView reports.
Last updated
LibreLink (FreeStyle LibreLink) uploads scanned and Bluetooth streamed glucose to the Abbott account with LibreView web reports for clinics, caching recent traces per phone for offline graphs. Sensors start per phone; one sensor talks to one app officially.
LibreView is the durable record with AGP analyses and care team sharing. Phone reinstalls restore account history while the active sensor needs starting fresh on the new device. Keep the reader or old phone running until overlap completes.
Where LibreLink stores this, by platform
Account cloud with LibreView (readings) plus app cache per phone
Start sensors in-app per device. Clearing app data drops local traces; LibreView keeps history. Export reports for appointments from either surface.
Account cloud with LibreView (same synced readings on iPhone)
Widgets and alarms configure per phone. Deleting the app clears cache only. New phones start a new sensor session; history syncs down regardless.
Frequently asked questions
can two phones share one Libre sensor
No, officially one sensor pairs with one app. The account merges nothing across simultaneous starters. Pick the daily driver phone for the sensor and share through LibreView instead.
how do I back up LibreLink history
It lives on the Abbott account with LibreView reports as the export path. Generate AGP PDFs per period for the clinic and personal archive. Phone cache needs no backup.
