📱 Mobile Packet Capture & Firewall Mobile Packet Capture & Firewall is a powerful, privacy-first network monitoring and security tool that lets you capture, analyze, and protect your device’s internet activity—without requiring root access. Built on a secure local VPN-based engine, the app not only inspects traffic but also actively blocks threats and unwanted connections in real time. All processing happens directly on your device—no remote servers, no tracking, and no data collection. 🔍 Key Features 📡 Capture Network Traffic (No Root Required) Monitor all incoming and outgoing connections using a secure local VPN interface. 📊 Analyze App Connections See which apps are accessing the internet, including domains, IP addresses, protocols, and connection details. ⛔ Advanced Firewall Control Block or allow connections with precision. Stop suspicious, unwanted, or background network activity instantly. 🛡️ Malware & Threat Detection Detect and block connections to known malicious IPs and domains using continuously updated threat intelligence sources. 📁 Export PCAP Files Save captured traffic in PCAP format for deep inspection using tools like Wireshark. 🧠 Smart Metadata Insights Quickly extract useful information such as hostnames, request data, and connection patterns. 🔐 100% Local Processing All traffic is captured, analyzed, and filtered entirely on your device. No external VPN servers. No third-party data sharing. No compromises. 🛡️ Privacy First Your data stays yours: • No remote servers • No tracking or analytics • No data collection • No ads tracking your activity Full transparency. Full control. ⚙️ How It Works Mobile Packet Capture & Firewall uses Android’s VPNService to create a secure local VPN tunnel. This allows the app to intercept, analyze, and filter traffic in real time, enabling both deep inspection and active protection—without sending any data outside your device. 🚀 Why Choose This App? Unlike traditional packet capture tools, this app combines network analysis + firewall control + malware protection in one lightweight, privacy-focused solution.
