Your health records never sit in a developer database.

Health Ledger separates where different types of data live so your personal records remain under your own Google account controls.

Your Health Connect Store

Weight, height, and sleep metrics stay inside Android Health Connect with local on-device caches. Read/write access adheres strictly to Health Connect permissions and Google API Services User Data Limited Use policies.

Your Google Drive appDataFolder

Food journal entries, meal photos, medical PDFs, medication courses, and AI chat threads are saved in your personal Google Drive hidden appDataFolder — inaccessible to the developer and erasable directly in Drive or the app.
