Abstract

The present disclosure relates to techniques for receiving glucose data from a continuous glucose sensor and controlling the use and redistribution of that data so it is used in an intended manner. In one aspect, a method includes obtaining one or more data points relating to glucose levels from a transmitter associated with a continuous glucose monitor device; distributing the one or more data points among one or more display devices and one or more servers; identifying a missing data point from among a display device of the one or more display devices or a server of the one or more servers, the missing data point being one of the one or more data points; and providing the missing data point to the display device or the server when the missing data point falls within a defined time period.

6. The method of claim 1, comprising:

identifying the missing data point from among a display device of the one or more display devices or a server of the one or more servers;

determining a number of the missing data points to backfill based on the device that missed the data; and

providing the determined number of missing data points to the display device or the server.

7. The method of claim 1, further comprising:

storing, by the one or more display devices or the one or more servers that was provided the missing data point, an indication that the missing data point comprises backfilled data.

8. The method of claim 1, further comprising:

storing, by the one or more display devices and the one or more servers, an indication that the one or more data points were received in real-time.
