Privacy

We don't collect your data.

Corpus has no analytics and no advertising. Signing in with Apple creates one account record on our server: your Apple identifier, your email if you choose to share it, and a monthly usage count so we can meter the AI quota. Your health data, meal photos and conversations live on your iPhone and nowhere else.

01
Everything stays on your device
Apple Health readings, meals, goals, chat history and settings are stored locally. Deleting the app deletes them; “Delete account” in Settings erases the server record.
02
AI requests pass through, they are not stored
When you chat or scan a meal, the request is relayed through our server to the AI provider and the reply is sent straight back. We keep only token counts for the monthly quota; we do not log, read or retain the content.
03
No tracking, no third-party SDKs
No analytics, advertising identifiers or crash-reporting services that send data off your phone.
04
You control Apple Health access
Corpus only reads the categories you approve, and you can revoke any of them at any time in the Health app.
How a request travels
Your iPhone
Data stored here. Only the current question and the context you allowed leave the device.
Corpus relay
Forwards the request and the reply. Only the token count is written down; never the content.

Generates the answer, which comes back the same way.
