The terms for using Piato.

These terms cover the Piato iPhone app and the website at piato.us. They are not legal advice.

What Piato is

Piato is a private nutrition diary. You sign in, log meals by typing, photographing a plate, picking a photo, or scanning a barcode, then edit calories and macros before you confirm. Coach drafts are estimates you can change. They are not medical advice, a diagnosis, or a treatment plan.

Your account

You need an Apple or Google sign-in to use the app. The same account works on iPhone and the website. You are responsible for the meals and photos you log. Do not use Piato for someone else without their permission.

Coach and photos

Typed Coach messages go to OpenAI so the app can identify food. Meal and Nutrition Facts photos are a separate share that you turn on in You. Camera permission is only for taking a picture. You can delete your account in You at any time.

What we do not sell

There are no in-app purchases, subscriptions, or ads. Apple Health is read only when you turn that connector on. Piato does not sell your diary.

Children

Piato is not directed at children under 13. Do not create an account for a child if that is not allowed where you live.

Changes

If these terms change, we update the date at the top of this page. Continued use after a material change means you should re-read them. These terms are not legal advice.
