How far back can I access my data?

It depends on how much data you have and your prescription i.e. how many times you use each sensor on a daily basis. You might be taking a controller/preventer medication twice a day and use your rescue/reliever medication as needed, but you can only access the most recent 5,000 logs recorded from each sensor you are using. Go to Where can I find my adherence data? and How does my Hailie™ app calculate my medication adherence? to learn about how your medication data is calculated and displayed in the Hailie™ app.
