Privacy Policy

Green Tea Nutrify is designed with privacy as a core principle. We operate primarily client-side, meaning your data stays on your device. We do not collect, store, or transmit personal information to our servers unless explicitly required for specific features. **What We Store Locally:** - Tea journal entries (tea type, amount, time, ratings, notes) - Caffeine tracking data (doses, timestamps, sleep times) - User preferences (theme, units, caffeine half-life settings) - Saved recipes and brewing parameters - AI conversation cache (questions and answers) **How It's Stored:** All data is stored in your browser's localStorage. This means: - Data never leaves your device automatically - No account or login required - No cloud synchronization (by design) - Complete control over your data - Can be cleared anytime via browser settings **Data You Can Export:** You can export your tea journal and caffeine tracking data as JSON files at any time using the Export feature in each tool.

To provide enhanced functionality, we use the following third-party services: **AI Services (for AI Tea Advisor):** - DeepSeek AI (primary): Processes your questions server-side to provide tea advice - OpenAI (backup): Used when DeepSeek is unavailable - Data sent: Your questions and optional context (journal statistics if enabled) - Data retention: We don't store your queries; rate limiting data stored locally - Cache: Responses cached locally for 24 hours to reduce API calls **Nutrition Databases:** - USDA FoodData Central: Public nutrition database for tea product information - OpenFoodFacts: Open database for product search with barcodes - Data sent: Search queries, barcode numbers - Data retention: API providers may log requests (see their privacy policies) **Future Services:** When traffic grows, we plan to integrate Google AdSense for revenue. Ads will be privacy-respectful and clearly marked.

We implement several measures to ensure your privacy: **1. No User Accounts:** - No email collection - No passwords to manage - No personal information required - Anonymous usage **2. Server-Side API Keys:** - All API keys are stored server-side only - Client never receives API credentials - Prevents key exposure and misuse **3. Local-First Architecture:** - All processing happens in your browser - No data uploads to our servers - Works offline once loaded **4. Minimal Data Transmission:** - AI queries only sent when you explicitly ask a question - Product searches only when you search - No background data collection - No telemetry without consent **5. No Cross-Site Tracking:** - No third-party tracking cookies - No social media pixels - No fingerprinting techniques

**Essential Cookies:** We use minimal browser storage for essential functionality only: **localStorage Items:** - Theme preference (dark/light mode) - Language preference - Tea journal entries - Caffeine tracking data - AI rate limiting counters - Saved recipes and brewing parameters **Session Storage:** - Temporary UI state - Cleared when browser closes **No Tracking Cookies:** - We do not use cookies for tracking - No advertising cookies (yet) - No analytics cookies without consent **Third-Party Cookies:** When we add Google AdSense in the future: - Advertising cookies will be used - You can opt-out via browser settings - Ad preferences managed through Google - GDPR/CCPA compliant
