Security

Security, without the small print.

LineFerry handles calls and texts, so you should know exactly where they travel. Here is what happens today, including what isn't protected yet.

What travels where

Data	Where it goes	Who can see it	Status
Call audio	Directly between your gateway and your iPhone, over your network.	Your devices. Not routed through LineFerry servers.	Encrypted between your devices
Text messages	Gateway to iPhone over your network; a notification is sent through Apple's push service.	Your devices; Apple's push service carries the sender and message text for the notification.	Notification passes through Apple
Incoming-call alert	An Apple VoIP push to your iPhone.	Apple's push service carries the caller's number and name, and the gateway's local address.	Passes through Apple
Call history and contacts	Stay on your gateway and your iPhone.	Your devices only.	Stays on your devices
Waitlist details	Email, gateway phone model and country, sent to our waitlist service.	LineFerry, to invite you. Never sold or shared.	Used only to invite you

The SIM never leaves a phone you own. We never hold your number.

Today calls and texts travel directly between your two phones.

We collect what we need to run the service and nothing to sell.

Only iPhones paired with the gateway's one-time QR code can connect, and everything between the gateway and the iPhone is encrypted. The phone call itself, between the gateway's SIM and the other person, is protected by your carrier like any mobile call.
The gateway phone is rooted, which removes some of Android's built-in protections. Use a dedicated phone for the gateway, not your personal phone.
Notifications for texts and calls are delivered by Apple's push service, like every iPhone app's notifications.

If you find a vulnerability, please tell us privately before sharing it. We'll acknowledge it and keep you updated.
