What you get

A simple, private VPN for Mac and iPhone.

WireGuard-based connections, no browsing or DNS logs, clear pricing — built for everyday use on public Wi-Fi, at home, or while travelling.

Built around the things that matter

Private browsing on public Wi-Fi, simple setup on Mac and iPhone, and a small, modern protocol underneath.

WireGuard Protocol

A modern, lean VPN protocol with strong cryptography and a small codebase that's easier to review.

Private by Design

We do not store browsing activity, DNS queries, or the originating IP address used for a VPN connection.

Servers Across Regions

Connect to servers in multiple regions for solid performance and access to region-restricted content.

Modern Encryption

ChaCha20-Poly1305 authenticated encryption with Curve25519 key exchange protects your traffic.

Automatic Kill Switch

Instantly blocks internet traffic if your VPN connection drops, preventing data leaks.

DNS Leak Protection

Secure DNS servers prevent your browsing history from being exposed to ISPs and third parties.
