title: Spam Reporting Application PRD

---

### Revised Timeline and Milestones (4 Weeks)

**Week 1: Planning and Initial Setup**
- Finalize requirements
- Design database schema
- Design API endpoints
- Set up project repositories (frontend and backend)

**Week 2: Frontend Development**
- Set up React Native project
- Implement reporting forms for SMS and calls
- Basic validation for required fields
- Integrate form submissions with mock backend

**Week 3: Backend Development**
- Set up Node.js project
- Implement API endpoints for reporting SMS and calls
- Implement data logging and standardization
- Integrate backend with frontend

**Week 4: Testing and Deployment**
- Unit and integration testing
- Performance testing
- Deploy application to production
- Final testing and bug fixing

### Prioritization Strategy

1. **Core Features First:**
   - **Frontend:**
     - SMS reporting form
     - Call reporting form
     - Integration with backend API
   - **Backend:**
     - API endpoints for SMS and call reports
     - Database logging and standardization

2. **Secondary Features:**
   - User authentication (optional for initial version)
   - Advanced validation and sanitization

### Product Requirements

#### 1. Introduction

**Project Name:** Spam Reporting Application  
**Objective:** To collect and consolidate spam SMS and calls from users, providing a centralized database for logging and analyzing spam activities.  
#### 2. Application Overview

The Spam Reporting Application allows users to report spam SMS and calls. The application will capture essential details about the spam and store them in a backend database for further analysis and reporting.

#### 3. Functional Requirements

**3.1 User Features**

- **Report Spam SMS:** Users can report spam SMS by providing the message time, phone number, and the message content. If there are multiple messages, users can report all related messages together.
- **Report Spam Call:** Users can report spam calls by providing the call time, phone number, and optional additional information about the call.

**3.2 Data Handling**

- **Frontend to Backend Communication:** The application should ensure secure and reliable transmission of reported data from the frontend to the backend.
- **Data Logging:** The backend should log each complaint individually with all the provided details.
- **Phone Number Standardization:** Ensure phone numbers are cleaned and standardized before storing in the database.

#### 4. Technical Requirements

**4.1 Frontend**

- **Framework:** React Native
- **Features:**
  - Form for reporting SMS
  - Form for reporting calls
  - Submission of reports to the backend API
  - Basic validation for required fields

**4.2 Backend**

- **Framework:** Node.js
- **Database:** Postgres/MongoDB (final decision to be based on data requirements)
- **Features:**
  - API endpoints for receiving spam reports
  - Logging reports in the database
  - Phone number cleaning and standardization
  - Data validation and sanitization

#### 5. Non-Functional Requirements

- **Security:** Ensure data transmission is secure using HTTPS.
- **Performance:** The backend should handle concurrent requests efficiently.
- **Scalability:** The system should be able to handle increasing numbers of reports without significant performance degradation.
- **Usability:** The mobile application should have a user-friendly interface for reporting spam.

#### 6. Database Schema

**Spam Reports Table:**
- **id (Primary Key)**
- **type (ENUM: 'SMS', 'Call')**
- **phone_number (VARCHAR)**
- **message (TEXT, nullable)**
- **call_info (TEXT, nullable)**
- **report_time (TIMESTAMP)**
- **created_at (TIMESTAMP)**
- **updated_at (TIMESTAMP)**

#### 7. API Endpoints

**POST /api/report-sms**
- **Description:** Endpoint for reporting spam SMS.
- **Request Body:**
  ```json
  {
    "phone_number": "string",
    "message": "string",
    "report_time": "timestamp"
  }
  ```

**POST /api/report-call**
- **Description:** Endpoint for reporting spam calls.
- **Request Body:**
  ```json
  {
    "phone_number": "string",
    "call_info": "string",
    "report_time": "timestamp"
  }
  ```

#### 9. Risks and Mitigations

- **Data Privacy:** Ensure sensitive data is encrypted and access is restricted.
- **Scalability:** Use efficient database indexing and consider load balancing for backend services.
- **User Adoption:** Provide a simple and intuitive user interface to encourage reporting.

#### 10. Appendices

- **Appendix A:** Wireframes (to be designed)
- **Appendix B:** API Documentation (to be created)
