how can we help?

The coach only sees what you've told it (today's caffeine, your goals, bedtime). If a question needs context it doesn't have, it asks rather than guesses.

Open the Health app → Sources → Caffi → make sure "Dietary Caffeine" is toggled on under "Allow Caffi to write data". The app prompts for this on the Connect Health step in onboarding, but you can also grant it after the fact.

In the app: Settings → Restart onboarding (clears local logs and signs you out). To also delete server-side data, email technuttiez@gmail.com and we will purge your Firestore document and Firebase Auth user within 7 days.

No — the app needs an account so your data syncs across devices and so we can write back to your private Firestore document. We do not store your Apple/Google password; only the unique account ID.
