Quarantine: App Firewall

C Sarath Babu

About this app

Quarantine is an advanced, privacy-focused network firewall that gives you granular control over how every application on your device accesses the internet. Stop silent data leaks, extend battery life, and protect your personal information with a single tap.

Why use Quarantine? Most apps communicate with servers in the background, consuming your data and battery without your knowledge. Quarantine acts as a local shield, allowing you to decide exactly which apps can connect to Wi-Fi or Mobile Data and when.

Key Features:

🔒 App-Level Blocking Easily toggle internet access for any installed app. Block social media distractions while working, or prevent background apps from wasting your mobile data.

⚙️ Smart Rules Engine Automate your digital security. Create custom triggers to block or allow internet access based on: • Current battery level • Specific Wi-Fi networks (e.g., block data on public Wi-Fi) • Scheduled daily time slots

📊 Real-Time Data Analytics Monitor exactly how much data each app is using. View real-time traffic and historical usage trends to identify data-hungry applications.

🛡️ Privacy First & No Root Required Quarantine uses the Android VpnService API to filter your traffic locally on your device. Unlike other firewalls, it does NOT require root access and NEVER sends your browsing data to external servers. It’s 100% private and transparent.

🔋 Extremely Lightweight Designed for efficiency, Quarantine runs with minimal impact on your battery and system resources.
