Privacy Policy

Last updated August 9, 2026

yommy is a local-first food log published by Great Ordinary. This policy explains what yommy handles when you use the iOS app and its nutrition-estimation service.

Information yommy handles

Meal data on your device

Your meal photos, descriptions, dates, meal labels, nutrition values, edits, and history are stored locally on your iPhone. yommy does not maintain a cloud copy of your food log. Exports and restores happen only when you choose them.

Data used for nutrition estimates

When you request an estimate, yommy sends the photo and/or description you selected to yommy’s Cloudflare service, which sends the content needed for the estimate to OpenAI. The service returns an estimate to your phone and does not store your photo, description, or completed meal record in its database.

Security, usage, and purchase data

yommy processes pseudonymous installation identifiers, Apple App Attest keys and counters, short-lived session records, request counts, and basic operational logs to secure the service and prevent abuse. For subscriptions, yommy processes App Store transaction identifiers, product and status information, purchase and expiration dates, and a pseudonymous app-account token. yommy does not require a yommy account.

How information is used

• Provide nutrition estimates and subscription features.
• Protect the service, enforce usage limits, and diagnose failures.
• Verify purchases and respond to App Store subscription changes.

Service providers

yommy uses Cloudflare for API hosting and security, OpenAI for nutrition estimation, and Apple for app distribution, App Attest, and in-app purchases. These providers process information on yommy’s behalf or under their own terms where applicable. yommy does not sell personal information or use meal data for advertising.

Retention and control

Local meal data remains on your device until you edit, delete, restore, or remove it. Estimate inputs are processed transiently by yommy’s service; infrastructure providers may retain limited data under their applicable service policies. Security, usage, and subscription records are kept only as reasonably needed to operate, protect, and account for the service.

You can delete individual meals in yommy, remove all local app data by deleting the app, and manage or cancel subscriptions in your Apple account. Because yommy has no user account, deleting the app does not automatically identify pseudonymous server records as yours.

Children

yommy is not directed to children under 13, and Great Ordinary does not knowingly collect personal information from children under 13.

Changes and contact

This policy may change as yommy evolves. Material updates will be posted here with a new date. For privacy questions, use the developer contact on yommy’s App Store page or visit Great Ordinary.
