Privacy Policy for CGM Glance

Effective Date: November 6, 2026
Application ID: ro.smakeru.cgmglance
Developer: Viorel D

1. Overview

CGM Glance is a free, open-source companion utility for Android phones and Wear OS watches that displays glucose readings already shown in the user's official Continuous Glucose Monitor (CGM) notification shade on a phone home-screen widget and on a paired Wear OS watch.

CGM Glance does not collect, transmit, store on external servers, sell, or share any personal or health data. The application does not even request the Android INTERNET permission.

2. Data Processed Locally on Your Device

Notification Reading (BIND_NOTIFICATION_LISTENER_SERVICE): Reads only the ongoing notifications posted by supported CGM companion apps (com.sinocare.cgm.ce for SinoCare LinX and com.dexcom.oneplus.* for Dexcom ONE+) strictly to extract the current glucose number, trend arrow, and timestamp. Notifications from all other apps are ignored.
Wear OS Sync: Transmits the latest glucose value locally to your paired Wear OS watch via the encrypted Google Play Services Wearable Data Layer.
Health Connect (Optional): If explicitly authorized by you, writes blood glucose records locally into Android Health Connect on your phone.

3. No Third-Party Sharing or Analytics

CGM Glance contains no advertising SDKs, no crash-reporting or analytics trackers, no cloud accounts, and no remote servers. All data remains strictly on your own phone and watch.

4. Medical Disclaimer

CGM Glance is a secondary informational display tool and is not a medical device. Always confirm glucose values in your official CGM manufacturer application before making any treatment or dosing decisions.
