Glucose Trends only accesses HealthKit for 1 purpose, to graph your glucose values. No Other data is requested by Glucose Trends App. The data itself is requested in Read Only mode so glucose data cannot be modified by The Glucose Trends App. Your data never leaves the confines of Glucose Trends and is never shared with anyone else.
