Your glucose data stays between your Mac and Dexcom.

Data RangeTrace accesses

RangeTrace accesses only the information needed to show the Dexcom Share account you follow and provide the features you enable:

• Dexcom account information. Your account name, password, and selected server region are used to authenticate directly with Dexcom Share. The password is stored in the macOS Keychain. The account name and region are stored in the app’s local preferences.
• Glucose readings. Current and recent readings are retrieved from Dexcom Share and processed on your Mac. A small latest-reading snapshot is stored locally so Current Glucose can work in Shortcuts and Spotlight without another network request.
• App preferences. Display choices, target ranges, alert settings, quiet hours, and related preferences are stored locally on your Mac.
• Notification permission. If you enable alerts, RangeTrace asks macOS for permission to deliver local notifications. RangeTrace does not use a remote push-notification service.

Data SKJ Apps collects

None. RangeTrace does not send personal information, health data, diagnostics, usage analytics, advertising identifiers, or crash reports to SKJ Apps. There is no SKJ Apps server or cloud account for RangeTrace.

Services RangeTrace communicates with

RangeTrace communicates with Dexcom Share to authenticate and fetch follower readings. Dexcom processes those requests under its own terms and privacy practices. Apple processes your Mac App Store purchase and any information associated with your Apple Account under Apple’s privacy practices. RangeTrace does not sell or share your data with advertisers or data brokers.

Retention, deletion, and your choices

Signing out removes the stored Dexcom credentials and latest-reading snapshot from RangeTrace. Display and alert preferences remain local until the app’s data is removed. To remove app-held information, sign out before uninstalling RangeTrace; macOS may otherwise retain Keychain items after an app is removed. You can revoke notification permission at any time in macOS System Settings.

SKJ Apps cannot retrieve or delete server-side account data because RangeTrace does not create an SKJ Apps account or transmit your data to SKJ Apps.

Security

The Mac App Store build runs in Apple’s App Sandbox, uses the macOS Keychain for your Dexcom password, and requests outbound network access only to retrieve Dexcom Share data. No security measure can guarantee absolute protection, so keep your Mac and Dexcom account secured with the protections available to you.
