Do I need an API key?

No. Grethel's coach is built in — just sign up and go. There's no key to get and nothing to configure. You can pick which model powers the coach under Settings → Coach settings.

A calorie estimate looks wrong.

Tell Grethel — "that was closer to 600" — and it will correct the entry. You can also tap a logged meal to edit it directly. The estimate is a starting point, and being roughly right every day beats being exactly right once.

How do I delete my account?

In the app: Settings → Delete account. It erases your profile, meals, weigh-ins, chat, and your stored key immediately and permanently. It cannot be undone.

Is Grethel medical advice?

No. It's decision support. For eating disorders, diabetes, medications, or unsafe goals, please talk to a qualified professional.
