Index
The FreeStyle Libre is a continuous glucose sensor whose readings are captured by the FreeStyle LibreLink phone app and uploaded to Abbott's LibreView cloud. It records your glucose history, and reports sent through the share function carry your first and last name and other health details to clinicians or connections via LibreLinkUp. Abbott integrates Libre data with electronic health-record systems and states it does not sell or license personal data except in a business transfer or joint-marketing program.
Why this rating
Deductions: continuous glucose monitoring is sensitive health data (-15); retention/processing language is vague (-7); a business-transfer clause means the account data could move in an acquisition (-5). Abbott's stated position that it does not routinely sell or license personal information — a stricter default than most consumer wearables — and TLS encryption keep the score comparatively high.

The evidence 1
Independent research, regulatory action, lawsuits, breaches and journalism about this device — the "what actually happens" axis. Each links to its source.
-
An FDA-posted Abbott safety notification concerning FreeStyle Libre reader hardware.
Why it matters here: Device-safety notification, not a data-privacy incident; included because no independent review of the app/LibreView privacy behavior exists — the privacy axis here is effectively unstudied.
