Why WireGuard on iPhone
CueVPN uses WireGuard on iPhonebecause it is the fastest, leanest VPN protocol available today. Its entire codebase is around 4,000 lines — compared to OpenVPN’s 100,000+ — which means a dramatically smaller attack surface and faster independent security audits. WireGuard has been part of the Linux kernel since version 5.6 and is formally integrated into both iOS and Android.
The encryption is ChaCha20-Poly1305, a cipher designed specifically for mobile processors. It runs fast on iPhonechips without draining battery, unlike AES-based alternatives that require hardware acceleration to match the same speed. Connecting takes under a second. Reconnecting after a network change — switching from Wi-Fi to mobile data, for example — takes under a second too.
What CueVPN protects on iPhone
CueVPN operates at the OS network level, so it encrypts traffic from every app on your iPhone — not just a browser. Email, banking apps, social media, background syncs, and any other network activity all route through the WireGuard tunnel. DNS queries go through the tunnel too, preventing your internet provider from seeing which domains you look up.
The kill switch blocks all internet traffic if the VPN tunnel drops unexpectedly. This matters when you move between networks — for example, locking your iPhone and reconnecting to a different Wi-Fi — where a brief unprotected window could expose your real IP. With the kill switch active, nothing escapes until the tunnel re-establishes.
Frequently asked questions
Does CueVPN work on older iPhones?
CueVPN supports iOS 15 and later, which covers iPhone 6s and newer. WireGuard runs efficiently on all of these devices — the protocol was designed with mobile hardware in mind and does not require a recent chip to perform well.
Does CueVPN drain the battery on iPhone?
No. WireGuard uses ChaCha20-Poly1305 encryption, which is specifically optimised for processors without hardware AES acceleration — exactly what mobile chips use. Idle WireGuard tunnels consume virtually no battery. CueVPN is designed for all-day use.
How does the kill switch work on iPhone?
CueVPN's kill switch is enabled by default and integrated into iOS's native VPN framework. If the tunnel drops — switching networks, server restart, or sleep — all internet traffic is blocked at the OS level until the WireGuard connection re-establishes. You do not need to configure anything.
Does CueVPN protect all apps on iPhone, including Safari?
Yes. CueVPN operates at the OS level via iOS's VPN network extension, so it encrypts traffic from every app on your device — Safari, Chrome, Mail, banking apps, everything — not just a browser.
Will iOS ask for permission when I first connect?
Yes. On first connection, iOS displays a system prompt asking permission to add a VPN configuration profile. This is a standard iOS security step for all VPN apps. Tap Allow, and from then on CueVPN connects silently with a single tap.
