🔒 100% LOCAL. ZERO TRACKING.
Your traffic never leaves your device. Nothing is logged, collected, or transmitted. No account required. DataShield works entirely offline on your phone.

**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.
