3. What Dia is — and is not

Dia is a wellness and educational tool that connects your glucose state to real-world factors and explains, in plain English, the context behind it. Dia is not a medical device and does not diagnose, treat, cure, prevent, manage, or monitor diabetes or any other condition. Dia does not provide medical advice and is not a substitute for a CGM, glucose meter, or professional medical care.

You agree not to use Dia to make decisions about insulin, medication, food, exercise, or treatment. Please review our Medical Disclaimer in full before using the Service.
