# TS LUXEWEAR - MULTI-STORE WOMEN'S FASHION PLATFORM ## PHASE 1 → CORE APP FOUNDATION **APP NAME:** TS LuxeWear **PLATFORM TYPE:** Multi-store women's fashion platform **DEVELOPMENT CONTEXT:** This project is built primarily from mobile using Google AI Studio, then pushed to GitHub, and deployed when needed. Workflow: 1. Build app/code using Google AI Studio on mobile 2. Push project to GitHub 3. Deploy frontend/web dashboards if needed 4. Use Firebase as backend 5. Use Cloudinary for product images This platform must be optimized for mobile-based development and free-tier services. **BUSINESS MODEL:** TS LuxeWear is a multi-store women's fashion platform where one platform supports multiple store owners. Example: - TS LuxeWear - Priya Boutique - Fashion Queen - Velvet Sarees - Ethnic Grace Each store owner manages their own store independently. Customers can browse products from different stores inside one unified app. **IMPORTANT:** This platform is completely FREE. Remove all subscription systems: - No paid plans - No upgrade plans - No subscription renewals - No commission system **PLATFORM REQUIREMENTS:** This should work like a real app and run smoothly on: - Android phones - iPhones - Tablets - Desktop computers - Laptops One codebase that supports all devices smoothly. The UI must be responsive, fast, premium, and production-ready. **SYSTEM ARCHITECTURE:** Build using multi-tenant architecture. Every store must have: - store_id - store_name - owner_name - owner_phone - owner_whatsapp - store_logo - store_banner - store_status (active/suspended) - store_url (unique URL for each store) - store_address_map_link (Google Maps link) - store_type - store_categories - store_followers_count - created_at Every product, order inquiry, review, category, and customer interaction must be linked with store_id. ## PHASE 2 → AUTHENTICATION & ROLE ACCESS **USER ROLES:** Build a role-based authentication system using Firebase. User roles: 1. super_admin 2. store_owner 3. customer 4. guest **AUTHENTICATION REQUIREMENTS:** Main app must NOT show Super Admin login publicly. Public users should only see: - Continue as Guest - Customer Login (Google) - Store Owner Login (Google) **HIDDEN ADMIN ACCESS:** Create a hidden admin route: /admin Example: myapp.com/admin Only these Gmail accounts must have "super_admin" access: 1. shakirsir2122@gmail.com 2. stalha2110@gmail.com No other Gmail account should ever receive super_admin access. If any other user tries to access /admin, block access and redirect them. **LOGIN FLOW:** After Google login, Firebase must verify the Gmail account. If Gmail matches one of the approved super admin accounts: → Redirect to Super Admin Dashboard If Gmail belongs to a store owner: → Redirect to Store Owner Dashboard If Gmail belongs to a customer: → Redirect to Customer Home Guest users: → Redirect to Guest Shopping Mode **SECURITY:** Protect all admin routes and admin dashboard pages. Unauthorized users must never access admin pages even if they manually type /admin in browser URL. ## PHASE 3 → PERMISSION SYSTEM & USER PRIVACY **PERMISSION REQUEST STRATEGY:** Implement a smart and professional permission request system. **IMPORTANT RULES:** - Do NOT ask all permissions immediately on app startup - On first app open, ask only the most essential/common permissions required for basic app functionality - Remaining permissions should only be requested WHEN the user actually uses a feature that requires that permission **CONTEXT-BASED PERMISSION REQUESTS:** **Camera Permission:** - Request only when user wants to upload/take product photo - Request only when user wants to update profile image - Request only when store owner wants to add product images using camera - Request only when customer wants to upload review photos **Gallery/Photos Permission:** - Request only when user selects images from device - Request only when uploading product images from gallery - Request only when changing profile picture from gallery - Request only when uploading images with reviews **Notification Permission:** - Request when user enables alerts for orders - Request when enabling product updates - Request when enabling promotional notifications - Request when enabling store updates - Request when following a store to get new product notifications - Request when enabling inquiry/question reply notifications - Request when enabling low stock alerts (store owners) **Location Permission:** - Request only if location-based features are used - Request only when user wants to find nearby stores (if applicable) **Storage/File Permission:** - Request only when downloading product images - Request only when uploading files or documents - Request only when saving invoices or receipts - Request only when downloading invoice PDF **PERMISSION FLOW REQUIREMENTS:** The permission flow must feel: - Professional - Modern - User-friendly - Privacy-focused - Non-spammy **BEFORE REQUESTING PERMISSION:** - Clearly explain WHY the permission is needed - Show context-appropriate message - Use friendly and transparent language Example: "To upload product photos, TS LuxeWear needs access to your camera. This allows you to take photos directly from the app." **HANDLING PERMISSION DENIAL:** If user denies permission: - Show limited fallback behavior where possible - Allow user to continue using other app features - Do not block entire app functionality - Provide alternative options when available Example: If camera permission denied: → Still allow user to upload from gallery → Continue browsing products normally **CROSS-PLATFORM PERMISSION HANDLING:** Ensure permissions work properly across: - Android - iPhone/iOS - Tablets - Desktop/Laptop browsers (where applicable) **PERMISSION RE-REQUEST LOGIC:** - If user denies permission initially, do not spam them - Allow user to manually enable permission later from settings - Show helpful message on how to enable permission from device settings if needed again **PRIVACY-FOCUSED APPROACH:** - Only request permissions that are absolutely necessary - Avoid unnecessary permission requests - Be transparent about data usage - Respect user privacy choices - Do not penalize users who deny optional permissions ## PHASE 4 → PUSH NOTIFICATION SYSTEM Implement a comprehensive push notification system using Firebase Cloud Messaging. **FOR CUSTOMERS:** Notification types: - Order status updates (Confirmed, Packed, Shipped, Delivered) - Order cancellation notifications - New products from followed stores - New offers/promotions from followed stores - Out-of-stock product restocked (from wishlist) - Reply to product inquiry/question - Review reply from store owner - Special festival/seasonal offers **FOR STORE OWNERS:** Notification types: - New order received - New customer inquiry/question on product - New customer review on product - Low stock alert (when stock falls below threshold) - Maintenance charge due date reminder - Customer return/refund request - New customer followed your store **FOR SUPER ADMIN:** Notification types: - New store registration - New customer complaint - New store complaint - Maintenance charge payment received - Suspicious activity alert - Platform milestone notifications **NOTIFICATION FEATURES:** - In-app notification center/inbox - Badge count for unread notifications - Notification history (last 30 days) - Mark as read/unread - Delete notifications - Notification sound toggle - Notification preferences (enable/disable by type) - Click notification to navigate to relevant page - Real-time delivery using Firebase - Notification grouping by category **NOTIFICATION PERMISSION TRIGGER:** - Request notification permission when user first enables any notification setting - Explain benefits before requesting permission - Allow granular control over notification types - Users can manage notification preferences anytime **OPTIMIZATION:** - Queue notifications to avoid spam - Smart notification timing (avoid late night) - Batch similar notifications - Notification throttling for repeated events ## PHASE 5 → SUPER ADMIN DASHBOARD Create a premium modern dashboard. **PLATFORM OVERVIEW:** - Total stores - Total customers - Total products - Total categories - Active stores - Suspended stores **STORE MANAGEMENT:** - View all stores - Approve stores - Suspend stores - Delete stores - View store performance **ANALYTICS:** - Top visiting store according to customer - Top viewed products - Customer growth - Daily active users - Most used function of app by Store - Add features that help monitor the stores for app improvement **FINANCIALS:** - Maintenance charge & due date with paid or not - Total earnings from particular store **ORDER MONITORING:** - View all orders/inquiries platform-wide - Monitor order status across all stores - Track order completion rates - View pending, confirmed, packed, shipped, delivered, cancelled orders - Store-wise order analytics - Customer order history across platform **SUPPORT:** - Customer complaints - Store complaints - Bug reports **NOTIFICATIONS:** - New login: Store/customer details - Complaints - Maintenance charge due date reminder from specific store - Low stock alerts - Suspicious activity alerts - New order/inquiry notifications ## PHASE 6 → STORE OWNER DASHBOARD Each store owner logs in and only sees their own data. **A.
