Periscope — A VPN to Your Own Home Periscope is a VPN that routes your traffic through your own home network instead of a rented data center. You keep one device running there — an Apple TV, a Mac or a PC — and your iPhone and iPad connect back to it from anywhere in the world. That one difference changes what a VPN is for. Your traffic leaves from your own address, so banks, local services and your own devices see the connection they expect. There is no country list to choose from, because there is only one exit: your home. PRIVATE BY DESIGN Your connection is end-to-end encrypted using WireGuard, one of the most secure VPN protocols available. This means your traffic is always private — even we can't see what you're doing. Whether you connect directly or through our relay servers, your data remains yours alone. WORKS FROM ANYWHERE Hotel WiFi blocking VPN connections? Challenging airport network? Periscope's smart connectivity automatically uses direct connection, NAT traversal, or relay fallback to establish a reliable tunnel — no manual configuration needed. FEATURES • Connect to your home network from anywhere in the world • Built on WireGuard — fast, modern, and battery-efficient • End-to-end encryption keeps your traffic private • Smart connectivity that works on restrictive networks • Real-time connection stats and diagnostics • Optimized for iPhone and iPad PERFECT FOR • Accessing your home network services while traveling • Connecting to devices on your home network • Keeping your browsing on your own trusted connection • Privacy-conscious travelers who don't trust public WiFi SIMPLE SETUP Install Periscope on the device that stays home and choose "Server". Install it on the iPhone and iPad you travel with, sign in with the same account, and tap connect. No admin console, no config files, no network settings to learn. FLEXIBLE PLANS Monthly or annual subscriptions. Start with a free trial. Travel the world. Stay connected to home.
