🔒 NETWORK SECURITY

🔐 PRIVATE DNS (DNS OVER HTTPS)
• Encrypt your DNS lookups so your browsing stays private
• Reduce snooping on public and shared Wi-Fi
• One-tap on/off — no technical setup
• This feature uses Android's VpnService to create a local, on-device VPN tunnel. The tunnel is used only to route your device's DNS queries to an encrypted DNS-over-HTTPS resolver. No other traffic is inspected, redirected, or sent through a remote server, and nothing is logged. When Private DNS is off, the VpnService is not active. Android will show a VPN key icon while it's running.

📤 SHARE WI-FI
• Share your own Wi-Fi with friends and guests in seconds
• No more spelling out long, complicated passwords

✨ WHY WIFI WARDEN
• Travel eSIM data, Wi-Fi tools and privacy together in one app
• Fast, clean, lightweight experience
• Available in multiple languages
• Built with privacy in mind — your data stays yours

Whether you need mobile data abroad with a travel eSIM, want to optimize your router at home, or just want a safer connection on public Wi-Fi, WiFi Warden keeps you connected — everywhere.

Note: WiFi Warden helps you analyze and manage networks you own or are authorized to use, and share your own Wi-Fi. It does not access or connect to networks without permission. WiFi Warden uses VpnService solely to power the optional Private DNS feature described above; it is not a general-purpose VPN and does not route your traffic through third-party servers.
