FAQ

Is my Dexcom Data safe?

Yes, the data is from the Dexcom API and your information is not hard coded and only runs locally so no data leaks.

How accurate is the forecast?

While the accuracy will depend on the noise or variation of your bloodsugar, Ill test it soon to give an actual estimation of accuracy.

Does it cost money?

As of right now, no. The base website is free to use and you can find the code at Github, however the robotic part will require purchase but it is currently unreleased.
