NetGuard is a free and open-source no-root firewall application for Android that blocks internet access per app using a local VPN. It allows users to individually allow or deny Wi-Fi and mobile data access for applications and addresses to reduce data usage, save battery, and increase privacy.
Use cases
- block an app from using mobile data but allow wifi
- no-root firewall for android
- stop apps from calling home
- block ads on android using a hosts file
- reduce data usage and battery drain
- log and analyze outgoing network traffic per app
- block internet access when roaming
When to choose
- you want per-app internet access control on Android without rooting
- you need an open-source firewall with no tracking or ads
- you want optional ad blocking via hosts files or per-address filtering
When to avoid
- you need to filter traffic on non-Android devices
- you need a root-based firewall with iptables-level control
- your device is not compatible with the VPN-based approach or runs Android below 5.1
