Whether you’re on a limited data plan, trying to improve your digital well-being, or simply want to know what your apps are doing behind your back, DataShield provides the ultimate app internet control in a beautiful, easy-to-use interface.

✨ Key Features:
🛡️ Smart Local Firewall: Act as your own internet blocker. Block any app from using mobile data or Wi-Fi with a single tap—no root required.
🧘 Digital Wellness & Mindful Shield (New): Build healthier digital habits. Set up a discreet wellness shield to monitor your habits, keep a streak of your clean days, and receive compassionate, mindful reminders when you need a screen break.
📊 Real-time Statistics (Data Usage Monitor): Monitor which apps are consuming the most bandwidth. See exactly how much you've saved and stop background usage dead in its tracks.
🔍 Advanced Privacy Auditor (Data Privacy): Instantly detect high-risk apps that demand sensitive permissions (like your camera or location) and monitor exactly how much data they are secretly uploading.
🌙 Sleep Mode & Deep Work: Create "Set-and-Forget" profiles. Automatically block distracting apps during the night, or disable social media and messaging during work hours so you can stay focused.
✈️ Roaming Shield: Instantly block heavy background data when you're traveling abroad to avoid expensive roaming charges and save mobile data.
🔋 Battery Saver: By preventing unnecessary background network activity and constant waking, DataShield acts as an Android firewall that helps your battery last significantly longer throughout the day.
🔒 Zero-Tracking Privacy: Unlike many other VPNs and data managers, DataShield is a true privacy protector that works 100% locally. Your traffic data never leaves your device and is never logged or tracked.
**Important Note Regarding VpnService: DataShield utilizes Android's VpnService to provide its core functionality as a local device firewall. The VpnService is strictly required to intercept network traffic locally on your device, allowing the app to selectively block internet access for specific apps you choose. DataShield does NOT act as a remote proxy, does NOT route your traffic to external servers, and does NOT collect, log, or transmit your internet data. All traffic processing happens 100% locally on your device to save your mobile data and protect your privacy.
