Privacy Policy for OnDiet AI

Effective date: March 25, 2026

This Privacy Policy explains how OnDiet AI handles information when you use the app and related services. It is written to reflect the current app behavior and relay architecture in this release.

1. What OnDiet AI does

OnDiet AI is an iOS app that helps users import nutrition plans, choose grocery and meal-prep preferences, generate shopping and preparation checklists, and track progress over time.

2. Information you provide

Depending on how you use the app, OnDiet AI may process the following information:

  • Nutrition plan files you import, including PDFs and images.
  • Plan settings you select, such as household size, prep style, grocery preference, language, and units.
  • Plan titles, generated sections, checklist items, and edits you make inside the app.
  • Subscription-related actions such as purchases and restore requests handled through Apple and RevenueCat.

3. Information stored on your device

OnDiet AI stores plan-related content locally on your device, including draft plans, imported assets, generated grocery and meal-prep sections, and checklist progress. This local storage is used so you can reopen plans, review edits, and continue using the app over time.

4. iCloud and Apple services

The app is configured to use Apple iCloud services, including CloudKit-related entitlements. If you use iCloud-enabled functionality, certain app data may be stored or synced through Apple services subject to Apple’s terms and privacy practices.

5. AI generation and relay processing

When you request generated grocery or meal-prep output, the app sends the required plan inputs and selected options through the OnDiet AI relay service. That relay is designed to verify app-originated requests, apply operational controls, and forward generation requests to Anthropic in order to produce the structured output returned to the app.

This means imported plan content and related generation settings may be transmitted to the relay and then processed by Anthropic for the purpose of generating your requested results.

6. App verification and security

OnDiet AI uses Apple App Attest-related verification flows to help confirm that requests to the relay are coming from a valid app installation. The relay may process attestation records, challenge records, request metadata, and related verification state in order to operate securely and reduce abuse.

7. Subscription and billing data

Subscription purchases and restores are handled through Apple’s App Store infrastructure and RevenueCat. OnDiet AI does not directly collect your full payment card information. However, subscription status, entitlement state, and product or offering metadata may be processed so the app can determine access to premium functionality.

8. Backend operational data

The relay service may store operational and security-related information such as attestation records, assertion counters, rate-limiting data, and request audit metadata. This data is used to keep the service functioning, protect against misuse, and support troubleshooting.

9. How information is used

  • To import, organize, and persist your nutrition plans and generated checklists.
  • To send generation requests and return grocery and meal-prep output.
  • To verify app-originated requests and protect backend services.
  • To restore subscriptions and determine premium access status.
  • To maintain service reliability, operational logging, and abuse protection.

10. Sharing

Information may be shared with service providers only as needed to operate the app, including:

  • Apple, for iCloud, App Store purchases, and App Attest-related platform services.
  • RevenueCat, for subscription and entitlement management.
  • Anthropic, for AI generation requested by the user.
  • Infrastructure providers used to host the OnDiet AI relay service.

11. Data retention

Local plan data may remain on your device until you delete it or remove the app. Server-side operational and security records may be retained for as long as reasonably necessary to operate, secure, and troubleshoot the service.

12. Your choices

  • You can choose whether to import PDFs or images into the app.
  • You can remove app data by deleting plans or uninstalling the app, subject to any iCloud sync behavior.
  • You can manage subscriptions through your Apple account settings.
  • You can choose not to use AI generation features if you do not want plan content sent through the relay.

13. Children’s privacy

OnDiet AI is not intended to knowingly collect personal information from children in violation of applicable law. If you believe information from a child has been provided improperly, contact the app operator so it can be reviewed.

14. Changes to this policy

This Privacy Policy may be updated from time to time as the app, backend services, or third-party providers change. The effective date at the top of this page will be updated when material changes are made.
