FAT ("Food AI Tracker") is developed by Jan Kollmorgen. This policy explains what data is collected, how it is being used, and your rights.
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.
We use Google's Gemini API to analyze food images and descriptions. When you submit a photo or text description, it is sent to Google for processing. Please refer to Google's Privacy Policy for details on their data handling.
Your food diary and weight records are stored locally on your device. Your account information is stored securely on our server. All communication between the app and our server is encrypted via HTTPS.
Your account data is retained as long as you have an account. Food photos are not retained on our servers. You can delete your local data at any time by deleting entries in the app or uninstalling the app.
You can request deletion of your account and associated server-side data by contacting us. Local data can be deleted by removing the app from your device.
FAT is not directed at children under 13. We do not knowingly collect personal information from children.
We may update this policy from time to time. Changes will be reflected on this page with an updated date.
