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. Download WiFi Warden and take control of your connection.
