PacketLock uses Android's VPNService API to create a local, on-device VPN that intercepts and blocks network traffic for selected applications. No traffic is routed through external servers. The VPN operates entirely within your device, giving you precise control over which apps can access the internet and when.
Why it's different
No external routing
Traffic is never sent to a remote server. The VPN runs locally on your device.
No telemetry
No usage data is collected, transmitted, or stored on external systems.
No analytics
Zero analytics SDKs. No Firebase, no Crashlytics, no event logging.
No cloud storage
All app configuration and data lives on your device and nowhere else.
