Welcome to the era of digital exams without cheating! Exam Browser is a dedicated browser application (kiosk mode) designed to maintain the integrity of computer-based (CBT) and web-based exams. It is suitable for Daily Assessments, PTS, PAS, ANBK, and even School Exams (US) using platforms such as Google Forms, Microsoft Forms, Moodle, Candy CBT, and others.

This application locks student access to only the exam page, blocking any cheating attempts, while still providing a comfortable and modern user experience like a professional browser.

🛡️ HIGH-LEVEL SECURITY FEATURES (ANTI-CHEAT SYSTEM):

✅ Screen Pinning: Students are locked within the application. Navigation buttons (Home, Back, Recent) are completely disabled. ✅ Screenshot & Screen Record Blocker: Prevents question leaks through screen captures or recordings. ✅ USB Cable Detection (NEW!): Detects and blocks screen mirroring or debugging attempts to connect to a laptop/computer via a data cable. ✅ Anti-Split Screen & Floating Apps: Ensures students don't open other apps (such as AI, browsers, or notes) side-by-side. ✅ Loss of Focus Protection: Automatic warning alarms sound if students try to open notifications or switch apps. ✅ Automatic Cache Clearing: Erases login traces and browsing history after a session for data security.

🚀 MODERN FEATURES & USER CONVENIENCE:

🔹 Multi-Tab Browser (NEW!): Supports up to 5 tabs simultaneously! Makes it easy for students to access reference materials (if permitted) or take sub-session exams without reloading the main page. 🔹 Smart QR Code Scanner: Log in to an exam without typing a URL. Simply scan the QR code from the teacher. Also supports Scan QR Code Out for mass efficiency. 🔹 Fullscreen & Zoom Display: Pinch-to-Zoom feature to clarify small question text, with a hidden address bar to keep the server URL private. 🔹 Time & Battery Indicator: A dedicated status bar within the exam to keep students aware of the time without having to pull down the system notification bar. 🔹 Intuitive Navigation: Easy-to-reach yet secure Back, Forward, and Refresh buttons.

🏫 EFFICIENCY FOR SCHOOLS & PROCTORS:

⚡ Mass Exit Management (Hassle-Free!): No need to type in PINs individually on hundreds of students' phones! Simply display the Exit QR Code on the projector, students scan it, and the app closes automatically. Very efficient for mass exams.

🔐 Dynamic Admin PIN: Forget about PINs that are easy for students to guess. This app uses an automatic Daily PIN system (date-based) that is unique every day, making it easier for teachers without the need for manual settings.

💎 UPGRADE TO PREMIUM (SCHOOL/ENTERPRISE FEATURES):

Want this exam app to look exclusive to your school and have military-grade server security? Upgrade via In-App Purchase to get:

🌟 1. Custom Branding (School Identity): Change the app logo, app header name, and app theme color to match your school's identity. Show professionalism to students and parents.

🔐 2. Custom User Agent (Server Key): The ultimate security feature! Schools can set a unique User Agent (e.g., sman1-secure-v1). The exam server can be set to deny access from regular browsers (Chrome/Firefox) and only allow access from your school's Exam Browser app. Anti-jockey and Anti-Bypass!

🔑 3. Static Admin PIN: Complete control is in your hands. Set a unique, school-specific exit PIN if you prefer a single, fixed code.
