04

NetDefendy works on standard Android devices without additional system privileges.

VpnService usage

VPN infrastructure used for firewall protection.

Android provides the VpnService interface so app traffic can be filtered locally on the device. NetDefendy uses this interface to enforce per-app network rules.

NetDefendy does not provide a remote VPN service and does not route your traffic through a server operated by the developer.
