AI Cooking Pal Privacy Policy

Last Updated: November 1, 2026

This Privacy Policy explains how personal information is handled when using the AI Cooking Pal application ("App"). Please read this before using the App. The App respects user privacy and is committed to protecting personal information.

1. Information We Collect

1.1 Information provided by users

  • Ingredient list: ingredient names entered for recipe generation
  • Health-related information such as allergies (optional): if you write allergies or dietary restrictions (for example, "no eggs") in the ingredient field, it is used only to exclude those ingredients from the recipe
  • Seasoning list: seasonings added or selected by the user
  • Favorite recipes: titles, descriptions, and steps of recipes saved as favorites
  • App settings: dark mode setting, automatic bookmark setting

1.2 Automatically collected

  • Usage statistics: AI feature usage count and app usage (Firebase Analytics)
  • Advertising identifier: Advertising ID used by AdMob for ad delivery
  • Device information: app version, device model, OS version
  • App Check token: integrity verification information for fraud detection (Google Play Integrity)

The App does not collect personally identifiable information (PII) such as name, email address, or phone number. The App does not require account registration. Information collected is limited to recipe-related data entered by users within the App and operational statistics.

2. How We Use Information

2.1 Main purposes

  • Recipe generation: providing AI-generated recipe suggestions based on entered ingredients and seasonings
  • Favorites: saving and displaying recipes the user has bookmarked
  • App settings: storing user preferences (theme, automatic bookmark, etc.)
  • Fraud prevention: verifying legitimate clients with App Check and applying a daily request limit for the App as a whole
  • Ad delivery: showing ads via AdMob to sustain the service
  • Service improvement: collecting statistics to improve the App

2.2 About AI Features

The App's recipe-generation feature sends the entered ingredient list and seasoning list, through a Cloudflare Workers proxy operated by us, to Cloudflare Workers AI (a service of Cloudflare, Inc. that runs Gemma 4, an AI model published by Google, on Cloudflare's infrastructure). The data is not sent to the Google Gemini API. Cloudflare does not use content processed by Workers AI to train AI models. This allows users to receive recipe suggestions that make use of their entered ingredients. The App does not attach any personally identifiable information to what it sends. However, because ingredients and seasonings are free-text fields, please do not enter personal information such as your name or address.

3. Sharing with Third Parties

3.1 Cloudflare Workers / Cloudflare Workers AI (Cloudflare, Inc.)

  • Shared information: text of ingredient and seasoning lists (including allergy or similar information if written), and the App Check token (integrity verification information for fraud detection)
  • Purpose: relaying through our proxy, AI-powered recipe generation (Gemma 4), fraud prevention and a daily usage limit
  • Route: sent from the App to our Cloudflare Workers proxy and processed by Workers AI on the same Cloudflare infrastructure. Not sent to Google
  • Use for training: none. Cloudflare does not use content processed by Workers AI to train AI models (Cloudflare Workers AI privacy)
  • Storage: we do not store ingredient or seasoning content or the AI's responses. Cloudflare does not retain inputs or outputs beyond what is needed to process the request
  • Usage limit: the daily number of requests is counted as a total for the App as a whole, using only an app identifier and the date, with no information that identifies an individual or device

3.2 Firebase (Google)

  • Firebase Analytics: collection of anonymized app usage statistics
  • Firebase App Check (with Play Integrity): blocking access from unauthorized clients
  • Data retention: per Google's data retention policy

3.3 Google AdMob

  • Shared information: advertising ID, coarse location, device information
  • Purpose: ad delivery and personalization
  • Resetting or opting out: available from the "Ads" section in device settings

3.4 Google Play Services

  • Features used: app update and review functionality
  • Collected information: app usage statistics and crash reports

We do not provide personal information to third parties beyond the above without user consent, except as required by law.

4. Data Storage and Security

4.1 Local data

  • Favorite recipes and seasoning lists are stored in the device's local database.
  • App settings and API call counts are stored in the device's SharedPreferences.
  • All local data is deleted when the App is uninstalled.

4.2 Security measures

  • All external communication is encrypted via HTTPS
  • Credentials and settings needed for the AI are not stored on the client; they are managed server-side (Cloudflare Workers)
  • Firebase App Check blocks access from unauthorized clients
  • A daily request limit for the App as a whole helps prevent abuse

5. User Rights

Users can access all data stored in the App. Stored information can be viewed and edited from the favorites, seasoning, and settings screens.

  • Deleting individual data: recipes can be removed on the favorites screen, and seasonings on the seasoning screen.
  • Deleting all data: all local data is deleted when the App is uninstalled from the device.
  • Resetting the advertising ID: available from the device Settings > Ads section.
  • Data deletion requests: to request deletion of data held by third-party services (such as Google), please contact us via the channel below.

6. Data Retention

  • Local data: retained until App uninstallation. Manually deleted data is removed immediately.
  • Cloudflare Workers AI: submitted content is not retained beyond what is needed to process the request (and is not used for AI training). Our proxy keeps only a record of an app identifier and date used for counting requests, which is deleted automatically after about 26 hours
  • Firebase / Google Play Services / AdMob: per Google's data retention policy

7. Children's Privacy

The App does not intentionally collect personal information from children under 13. If a child under 13 uses the App, please do so under parental supervision.

8. Changes to Policy

This Privacy Policy may be updated as needed. Important changes will be announced within the App or in the release notes on Google Play Store. Updated policies take effect upon posting on this page.

9. Contact

For questions or concerns about this Privacy Policy, please contact us via the app review section on Google Play Store. We will respond as promptly as possible.
