Kyberlink is a fast, beautifully designed WireGuard® VPN client for iPhone and iPad. Bring your own WireGuard configuration — from your home lab, a VPS, or your workplace — and connect with a single tap. Kyberlink is a client, not a VPN service: no accounts, no subscriptions, and we operate no servers. Your traffic goes straight to the server in your own config, and your keys never leave your device unencrypted. WHY KYBERLINK • One-tap connect with a clean, animated home screen • "Am I actually protected?" — a built-in Connection Check confirms your traffic is encrypted, exiting through the VPN, and using your tunnel's DNS • Connect to Fastest — pings your servers and connects to the lowest-latency one, ideal when you keep multiple regions • Import in seconds — scan a QR code, open a .conf file, or paste a config PRIVACY & SECURITY, DONE RIGHT • Private keys stored in the iOS Keychain with device-only protection • Optional iCloud backup is encrypted on-device (AES-GCM); the key lives only in your end-to-end-encrypted iCloud Keychain • App Lock with Face ID / Touch ID, plus biometric confirmation before exporting keys • No analytics, no tracking, no telemetry — ever POWERFUL, YET SIMPLE • Multiple tunnels with groups, notes, reordering, and duplication • On-Demand VPN (Wi-Fi only, cellular only, or always on) • Trusted Wi-Fi networks that auto-disconnect at home or the office • Allow Local Network — reach your printer or NAS while connected • Server-down alerts if a tunnel stops responding while you're connected • Live stats: uptime, real-time speed, last handshake, and per-tunnel data usage • Latency testing and public IP display • Connection history log EVERYWHERE YOU NEED IT • Home Screen and Lock Screen widgets • Live Activity & Dynamic Island while connected • Siri Shortcuts — "Connect to Work VPN," "Connect to fastest" • Full iPad support, all orientations • Localized in English, Turkish, Spanish, and German Kyberlink requires a WireGuard configuration from your own VPN server or provider.
