MEDICAL DISCLAIMER

GlucoseSync is not a medical device. It does not diagnose, treat, cure, or prevent any medical condition. GlucoseSync is a companion display app that shows glucose data provided by third-party CGM systems. Always consult a qualified healthcare professional before making any medical decisions based on the information displayed in this app. Do not use GlucoseSync as a substitute for professional medical advice, diagnosis, or treatment.

IMPORTANT

GlucoseSync is a companion app. It reads glucose data from your CGM manufacturer's cloud service or from xDrip+ on your device. It does not read sensor data directly from CGM hardware (except via xDrip+). The manufacturer's app must remain installed and uploading to the cloud for cloud-based providers to work.
