Introduction

Quick Attendance is a high-performance, local-first attendance management ecosystem designed to eliminate the inefficiencies of manual roll-calling. By leveraging dynamic QR technology and local network synchronization, the system provides a tamper-proof method for verifying student presence in real-time without requiring expensive cloud infrastructure.

System Background

Traditional attendance systems often suffer from two flaws: "Proxy Attendance" (where students sign in for absent peers) and privacy concerns related to cloud-stored data. Quick Attendance solves these issues through a Server-Client Architecture:

• The Desktop Server (Lecturer): Acts as a localized hub. It generates unique, time-sensitive session tokens and stores all academic records locally on the lecturer’s hardware. This ensures that sensitive student data never leaves the institution’s control.

• The Mobile Client (Student): Uses encrypted device-binding to ensure that one device equals one student. By scanning the lecturer’s dynamic QR code, the student’s presence is validated and recorded within seconds.

Core Pillars

• Data Sovereignty: Your data stays on your machine.

• Anti-Proxy Security: Device ID mapping prevents duplicate check-ins.

• Network Efficiency: Works over local Wi-Fi/Hotspots, making it resilient to poor internet connectivity.

Desktop App (Server / Lecturer Edition) Privacy Policy & Data Handling

This policy explains how Quick Attendance ensures your attendance data remains under your absolute control.

1. Data Collection & Transmission

• Privacy by Design: This application does not capture your screen or transmit data to external third-party servers.

• Local Peer-to-Peer: The app functions as a local server, receiving check-in data directly from students. Processing and storage happen exclusively on your system.

• No Activity Logs: We do not track your usage or transmit application data out of your local environment.

2. Local Storage & Control

• Host-Side Sovereignty: All records are controlled on the lecturer's PC. There is no centralized cloud database; your data lives in the local installation directory.

• User Access: You have full authority over the database. You can view, export, or delete records via the app UI or the file system.

• Recovery Disclaimer: Because data is stored locally, any files deleted (intentionally or otherwise) cannot be recovered by the developers.

3. Usage, Liability & Updates

• Free Version: This is the standard free version of Quick Attendance.

• Mandatory Updates: To maintain security and protocol compatibility between the server and mobile client, updates are required whenever a new version is released.

• Liability: We are not liable for data loss or damage resulting from the use of this software.

4. Current Scope

• Individual Use: This version is optimized for individual lecturers. A centralized Enterprise version for institutions is currently in development.

📖 Mobile App: User Guide

Quick Attendance makes recording your presence fast, secure, and seamless.

1. Getting Started

• Profile Setup: Launch the app and register your profile using your Full Name and Student ID.

• Network Connection: Ensure your device is connected to the specific network (e.g., Campus Wi-Fi) required to communicate with the lecturer’s local server.

2. Checking In

• Scan to Join: Navigate to the Home screen and scan the session QR Code projected by your instructor.

• Manual Entry: If your camera is unavailable, enter the provided Session PIN manually to complete your check-in.

3. Timetable & Management

• Schedule: Access the Timetable tab to view your weekly class schedule and upcoming sessions.

• Profile: Use the Profile tab to update your details, manage linked accounts, or sign out.

🔒 Privacy Policy

Your privacy is our priority. Here is how we handle your information:

• Data Points: We collect your Name, Student ID, and Device Identifier (MAC Address).

• Integrity Checks: Device identifiers are used strictly to prevent "Proxy Attendance" (checking in for someone else) and to ensure the integrity of the academic record.

• Secure Transit: Data is transmitted using industry-standard encryption directly to the lecturer’s server.

• Third-Party Services: The app may include minimal integrations (such as banner ads) that collect anonymized metrics. These operate under their respective providers' privacy policies.

 

---

🗑️ Account and Data Deletion

You maintain control over your digital footprint:

1. Local Device Data: To wipe your session and profile from your phone, go to Profile > Sign Out. This clears all local cached data.

2. Official Records: Because attendance records are academic logs, permanent removal of historical data from the lecturer’s system must be requested directly through your Lecturer or Department Head.

---

📞 Support & Feedback

Connection Issues?

• Network: Double-check that you are on the correct institutional Wi-Fi.

• Server Status: If you cannot connect, verify with your instructor that the server session is active.

Technical Inquiries: For bugs or feedback, contact the developer at: 📧 raphaelraymondproduct@gmail.com

Path Finder( Travelling salesman problem Solution and Game)

🧭 Path Finder

Solve and play the Travelling Salesman Problem (TSP) in a fun, visual way.
Path Finder combines a shortest path game and a TSP-solving tool — helping you learn, experiment, and optimize real-world route problems.

---

📱 Download on Google Play

Download App
Or search: "Path Finder Raph Ray" on Google Play Store.

---

1️⃣ Introduction

Path Finder is both a game and a problem-solving tool for the
Travelling Salesman Problem (TSP).

In the Shortest Path Game, you’re given multiple points (stations) and must find the most efficient route to visit all of them and return to the starting point — similar to optimizing delivery routes or minimizing travel costs.

💡 Tip: When playing, aim to form a cyclic path that connects all stations.

 

In Find My Path (TSP Solver) mode, you can:

• Enter locations or distances between points.

• Upload or capture a map image.

• Tap points directly on the image to compute the shortest route.

---

🗺️ Example Scenario

Imagine distributing vaccines to multiple airports and returning to the base.
Path Finder helps minimize transport costs by optimizing the order of visits.

---

⚙️ Choosing Your Input Method

You can define your TSP problem using one of the following methods:

• 🖋️ Type Locations:
  Enter coordinates when you know distances (e.g., by air or road).
  Both location and graph structure are important here.

• 🖼️ Load Map Image:
  Upload a map photo, then tap to mark the points.
  The points represent approximate locations on the image.

• 📏 Enter Distances or Costs:
  If you know only the travel costs (distances) but not coordinates, input them directly.
  Only cost data matters; the graph visualization is optional.
