Keep your information private
Inputs and logs stay in page memory. No account, upload, health-data analytics, browser storage or medical-record synchronization. Leaving or refreshing the page can clear the session; explicitly downloaded files contain your information. Exports are local PNG/PDF summaries, CSV schedules or logs, and a sleep calendar where offered. These tools are for general planning and estimates, not diagnosis or individualized treatment.
