Chef++ (the "App") is an application for managing grocery lists and recipes, provided by an individual developer (the "Developer"). This Privacy Policy explains what information the App collects and how that information is handled.
1. Information We Collect
- Account information: your email address (when you sign up with email and password) and basic Google account information (when you sign in with Google)
- Content you enter or upload: grocery list items, recipes (title, ingredients, steps, tags, etc.), and photos of recipes and ingredients
- Usage information: records of screen views and feature use (such as logging in, creating recipes, and using AI features), and device and app identifiers (including the advertising ID on Android)
- Error information: app crash logs, error logs, and a record of the actions just before an error (screen navigation and feature calls; this does not include anything you entered)
2. How We Use Information
- To provide the grocery list and recipe management features
- To verify your identity and manage your account (sending emails to verify your email address and to reset your password)
- To provide AI features (recognizing ingredients in photos, generating recipes from photos of dishes, suggesting recipes from purchased ingredients, and automatically generating recipe images). For these features, uploaded images and entered content are sent to the external AI services listed below for processing
- To prevent unauthorized use (invitation-only access control)
- To investigate bugs and improve the quality of the App
- To analyze how the App is used (to understand which features are used and how often)
3. Third-Party Services
The App uses the following services to process data. The privacy policy of each service applies to its use.
- Firebase (Google): authentication, database (Firestore), and file storage
- Google Cloud Vertex AI: ingredient recognition in photos and recipe suggestions
- Hugging Face: automatic generation of recipe images
- Have I Been Pwned (Pwned Passwords): checking whether your password has appeared in past data breaches when you sign up or change your password (only the first 5 characters of a hash of your password are sent, never the password itself)
- Firebase App Check (Google; reCAPTCHA on the web app, Play Integrity on the Android app): verifying that requests come from the genuine app, to prevent abuse (information about your browser or device and the app is sent to Google)
- Firebase Crashlytics (mobile app) / Google Cloud Error Reporting (web app): crash and error monitoring
- Google Analytics for Firebase (Google): analysis of app usage
We do not sell or provide your personal information to any third party other than those listed above without your consent.
