Phone Guardian helps protect your privacy and online activities when using WiFi. The app uses a VPN (Virtual Private Network) technology to scan your internet traffic for unprotected data. If it detects unencrypted data while you’re connected to an unsecured WiFi network, it will automatically encrypt that traffic to protect it from hackers and other incoming threats.
Unlike traditional VPN services, the Phone Guardian does not hide your IP address or physical location. While traditional VPN services usually cost around $5 or $10 per month, Phone Guardian is completely free.
