Skarval - Firewall & VPN

Skarval is a per-app firewall for Android. It uses the VpnService API to show you which app is connecting where, and lets you block any of them. No root required. Note: Skarval is a local VPN that works entirely on your device. It cannot unblock geo-restricted content through overseas servers. CONTROL TRAFFIC PER APP For every installed app you can allow or block Wi-Fi, mobile data, LAN and background traffic independently. Stopping apps that keep talking to the network while you are not using them also saves data and battery. - Allow or block network access per app - Block background traffic only - Fine-grained port and protocol rules - Newly installed apps start fully blocked, so nothing slips through SEE THE TRAFFIC YOU NORMALLY CANNOT Every connection made while protection is on is recorded on your device. You can see which app connected, when, to where, and through which route. - App name, destination, port, protocol and byte counts - Route shown as direct, encrypted DNS, Tor, I2P or blocked - Trackers and overseas destinations highlighted - Chronological view and per-app summary DNS AND TRAFFIC PROTECTION - Encrypted DNS via DNSCrypt, DoH and DoT - Block other apps' own encrypted DNS (DoT / DoH / DoQ / ODoH) - Route traffic through the Tor network (all traffic, or DNS only) - Connect to the I2P network - SNI obfuscation - Automatic protection when joining public Wi-Fi - Scheduled blackout windows NOTHING LEAVES YOUR DEVICE We run no VPN servers. Traffic is processed on the device and never passes through any server of ours. The traffic log is stored only in a local database and is never uploaded. The app contains no advertising or analytics SDKs, and requires no account or sign-in. SKARVAL PRO (ONE-TIME PURCHASE) All core features are free.
