Wallivex – App Firewall overview

Wallivex is a modern, privacy-first local Android firewall designed to give you complete control over which apps can access the internet — without requiring root access. ═══════════════════════════════════════════ VPNSERVICE USAGE DISCLOSURE & DOCUMENTATION: ═══════════════════════════════════════════ Wallivex utilizes Android's VpnService to establish a secure, local on-device network loopback interface. The use of VpnService is strictly required to provide the core functionality of the application: 1. Why VpnService is required: • On-Device Packet Filtering: Non-rooted Android devices do not allow apps to inspect or filter network traffic of other applications directly. By creating a local loopback interface via VpnService, Wallivex can intercept and manage network packets directly on your device. • Per-App Traffic Control: VpnService allows the app to identify which installed package is initiating a connection, enabling granular per-app internet access rules. 2. Relevant features relying on VpnService: • Per-App Firewall: Restrict or allow internet access for any installed application with a single tap. • Background Telemetry Prevention: Unwanted background connections and tracker requests from blocked apps are dropped immediately at the device level using VpnService. • Private DNS Resolution: DNS queries can be routed through the VpnService to privacy-respecting encrypted DNS providers (such as AdGuard DNS, Cloudflare 1.1.1.1, and Quad9) to block ads, malicious domains, and tracking. 3. 100% On-Device Processing – No External VPN Routing: • Wallivex does NOT operate any external or remote VPN servers. • Your private network traffic is NEVER routed through any external proxy or remote server. • All packet inspection and filtering take place 100% locally on your smartphone. • No connection logs are stored, no analytics are gathered, and no user accounts are required. ═══════════════════════════════════════════ KEY FEATURES: ═══════════════════════════════════════════ • Per-App Firewall: Control internet access for each app individually with ease. • Zero-Overhead Performance: Allowed applications bypass filtering directly for maximum connection speed and optimal battery efficiency. • Leak Prevention: Discard background telemetry and unwanted data drains from restricted applications. • Encrypted DNS Presets: Integrated support for AdGuard DNS, Cloudflare (1.1.1.1), and Quad9 malware protection. • 2026 Material 3 UI: Clean cyber-shield dashboard with animated protection status, live statistics, and instant search. • Quick Settings Tile: Toggle firewall protection directly from the Android quick settings shade. • 100% Free & Ad-Free: No ads, no subscriptions, no in-app purchases, no third-party trackers.
