Privacy Policy

Last updated: March 2026

FAT ("Food AI Tracker") is developed by Jan Kollmorgen. This policy explains what data is collected, how it is being used, and your rights.

Data Collection

Account Information: When you sign in with Apple, we receive your Apple user identifier, and optionally your email address and name (only if you choose to share them). We do not receive or store your Apple password or any other personal information.

Food Photos: When you take or select a photo for analysis, it is sent to our server and forwarded to Google's Gemini AI for nutritional estimation. Photos are processed in real time and are not stored on our servers after analysis is complete.

Nutrition Data: The AI-generated nutritional estimates (calories, protein, carbs, fat, fiber, sugar, sodium) are stored locally on your device. We do not store your food diary on our servers.

Health Data: With your permission, FAT writes nutrition and body weight data to Apple Health. This data stays on your device and is governed by Apple's privacy practices.

Usage Data: We track the number of analyses per month for rate limiting purposes. We do not track your activity, location, or browsing behavior.

How We Use Your Data
