Privacy Policy

Applies to the Wheat mobile application  ·  Last updated: October 2026

Plain-language summary: Wheat stores your account email and shared ingredient research in the cloud. Your scan history and preferences never leave your device. We use AI services to research ingredient safety, and collect app usage statistics and crash reports, not linked to your account, to improve Wheat. If you choose to, you can contribute product photos to Open Food Facts, a public database. We do not sell your data.


01 Who We Are

Wheat is a mobile application published by H5 STUDIO, LLC, a limited liability company registered in the State of Washington, USA.

02 What We Collect

Information you provide

  • Email address — collected when you create an account
  • Password — stored as a secure hash by Firebase Authentication; we never see it in plaintext

Your account record

If you create an account, we store your email address, when the account was created, when you last signed in, and its status. Nothing else is stored in your account.

Using Wheat without an account

Without an account, Wheat connects to our servers with a random anonymous identifier created by Firebase Authentication, which is not linked to your name or email address. You can scan up to 10 different products; creating an account and signing in lets you scan more.

Anonymized shared research data

When you scan a product barcode, Wheat looks up ingredient safety information. The research results are cached in our database indexed by barcode and ingredient name — not by your identity. This shared cache benefits all users and is not linked to your account.

What stays on your device only

  • Your scan history (which products you scanned and when)
  • Your preferences: allergen filters you have enabled and your shopping country
  • Locally cached product data for offline access

This data is stored in a local database on your phone. We cannot access it, and it is permanently deleted when you uninstall the app.

Camera and photos

Wheat uses your camera to scan product barcodes. Barcode scanning happens on your device, and those camera images are never transmitted.

When a product is missing from Open Food Facts, or has no ingredient list there, Wheat offers to photograph its packaging (front, ingredient list and nutrition label) and contribute the photos to Open Food Facts. This is always your choice: nothing is uploaded unless you take the photos and confirm the upload. The photos are sent, with the product's barcode, through our servers to Open Food Facts under Wheat's contributor account; we do not keep a copy. They are not linked to your account or email address.

Photos you contribute become part of the public Open Food Facts database and are published under its open licence (Creative Commons Attribution-ShareAlike). Avoid including people or personal information in them. Once published, they are managed by Open Food Facts; to ask for removal, contact Open Food Facts (openfoodfacts.org).

Usage statistics and crash reports

To understand how Wheat is used and to fix problems, the app sends to Google Firebase:

  • Usage events — for example products scanned (by barcode), research completed, settings changed (such as the number of allergen filters), and features used (problem reports, tips, sign-out, account deletion), along with device model, operating system and app version, and an approximate country derived from your IP address
  • Crash reports — when the app crashes or hits an error: the error, device model, operating system and app version, and the state of the app at the time

These are tied to a random app-instance identifier created by Firebase, not to your account, email address or name. They are collected in released versions of the app only.

App protection

To protect our servers from abuse, Wheat uses Firebase App Check. It asks Google Play Integrity (Android) or Apple DeviceCheck (iOS) to confirm that requests come from a genuine copy of the app on a genuine device. This check gives us no personal information.

Tips

If you leave a tip in Wheat, the payment is handled entirely by Apple (App Store) or Google (Google Play) under your store account. We never receive your payment details or your identity; we only record, in our usage statistics, that a tip of a given size was made.

Problem reports

If you report a problem, we store your message together with the product's barcode and name (when the report is about a product) and your device platform (iOS or Android). Reports are not linked to your account or email address, so please don't include personal information in them.

What we do not collect

  • Precise location data
  • Advertising identifiers
  • Your personal eating habits or dietary history
  • Payment information

03 How We Use Your Data

  • Account authentication — to verify your identity and secure your account
  • Ingredient research — barcodes and ingredient names are used to look up and cache safety data in our shared database
  • Service improvement — aggregate, anonymized usage data may be used to improve research quality
  • App stability and improvement — crash reports and usage statistics, to fix bugs and understand which features are used
  • Problem reports — to investigate and fix the issues you report
  • Abuse prevention — App Check verification of requests to our servers
  • Open Food Facts contributions — to send the product photos you choose to share

We do not sell, rent, or trade your personal data to third parties for marketing purposes.

05 Data Retention

  • Shared research cache — retained indefinitely; it is anonymized and not linked to any account

Photos you contributed to Open Food Facts are managed by Open Food Facts.


06 Your Rights

Depending on your location, you may have the right to:

  • Access the personal data we hold about you
  • Correct inaccurate data
  • Request deletion of your data (right to be forgotten)
  • Object to or restrict certain processing
  • Data portability

To exercise any of these rights, contact us at [email protected]. We will respond within 30 days.

California residents (CCPA): You have the right to know what personal information is collected, to request deletion, and to opt out of the sale of personal information. We do not sell personal information.

EU/EEA residents (GDPR): The legal basis for processing your email address is contract performance (providing the service you signed up for). Usage statistics, crash reports, App Check verification and problem reports are processed on the basis of legitimate interest in keeping Wheat working, secure and improving. Photos you contribute to Open Food Facts are sent with your consent, given each time you confirm an upload. You may withdraw consent at any time by deleting your account.


07 Children's Privacy

Wheat is intended for users aged 16 and older. We do not knowingly collect personal information from children under 16. If you believe a child under 16 has provided us with personal information, please contact us at [email protected] and we will delete it promptly.


08 No Medical Advice

Wheat is an information tool, not a medical service. Ingredient scores and health summaries are based on publicly available research and AI analysis. They are not a substitute for professional medical advice, diagnosis, or treatment. Always verify ingredient information on the physical product label, especially if you have allergies or specific health conditions.


09 Changes to This Policy

We may update this policy from time to time. We will notify users of material changes via an in-app notice or email. Continued use of Wheat after changes take effect constitutes acceptance of the revised policy.

This policy was last updated in October 2026.
