Last updated: June 13, 2026

This Privacy Policy describes how Dietz AI ("we", "us", or "the app") collects, uses, and protects your information when you use the Dietz AI mobile application — a calorie and macro tracker with AI-powered meal scanning. By using the app, you agree to the practices described below.

1. Information We Collect

• Account information: When you sign up, we collect your email address and name through Firebase Authentication, including via Google Sign-In and Sign in with Apple.
• Health and dietary data: Meals you log, calories, macros, weight, goals, and related nutrition information you enter or that the app calculates.
• Photos and images: Photos of meals you capture or upload for AI-based food recognition. Images may be processed by our AI provider to identify foods and estimate nutrition.
• Voice input: If you use voice logging, audio is processed on your device or by speech-recognition services to convert speech to text.
• Barcode data: Product barcodes you scan to look up food items.
• Purchase information: Subscription and purchase status managed through Google Play Billing and RevenueCat. We do not collect or store your full payment card details.
• Device information: Basic device and app metadata (such as device model, OS version, and app version) used for diagnostics and support.
