Privacy Policy
Last updated: April 1, 2026
Fud AI ("we", "our", "the app") is an open-source iOS app developed by Apoorv Darshan. This privacy policy explains how your information is handled.
Information You Provide
- Name, gender, date of birth, height, weight, and body fat percentage (entered during onboarding)
- Food photos taken within the app
- Food entries and nutrition data you log
- Weight log entries
- Dietary preferences and fitness goals
- AI provider API keys (stored in iOS Keychain)
How We Use Your Information
- AI Food Analysis: Food photos, text descriptions, and voice input are sent to your chosen AI provider (e.g. Google Gemini, OpenAI, Anthropic Claude, etc.) for nutritional analysis. You bring your own API key. We do not proxy or intercept these requests.
- Local Storage: All food entries, weight entries, user profile data, and food photos are stored locally on your device. Nothing leaves your device except AI analysis requests.
- API Key Storage: Your API keys are stored in iOS Keychain — encrypted hardware storage accessible only to the app on your device.
- Apple Health: If you enable Apple Health integration, the app writes body mass, height, and body fat percentage to HealthKit, and reads body mass, height, body fat percentage, date of birth, and biological sex from HealthKit.
Information We Do NOT Collect
- We do not use any third-party analytics, crash reporting, or advertising SDKs
- We do not track your behavior, location, or browsing activity
- We do not sell, share, or transfer your personal data to any third parties
- We do not operate any servers — all data stays on your device
- We do not require an account, sign-in, or cloud sync
