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.
