Follow the line.
Someone is waiting
A phone call you type.
Every keystroke appears live on the other screen. No send button. No saved conversations.
What is The Line
The Line is a one-to-one, real-time text app. You don't send messages. You open a line to one person, and as you type, they watch your words appear. As they answer, you watch theirs.
It works like a phone call, except you type instead of talk.
Look someone up. Their phone rings.
They pick up, and the line is live.
You both type at once. Every keystroke arrives as it happens.
End the line, or let it close after 60 seconds with nobody typing.
Experience live typing
Two phones, one line. Watch each letter land on the other screen as it's typed.
A simulated line between Maya and an anonymous user, @line7k2wq. Maya rings; the other phone shows Answer and Decline; they answer and both screens show LIVE. Each person's typing appears on the other screen letter by letter, mistakes and corrections included:
The text fades from both screens after 30 seconds. After 60 seconds with nobody typing, the line closes.
A simulation of the app's live screen, running entirely in your browser. Nothing here is sent anywhere, and nobody is on the other end.
No send button
Typing is the conversation. The other person sees you pause, correct yourself and start again, the way they'd hear you on a call.
Conversations without history
What you type fades from the screen after 30 seconds. When the line closes, the conversation text is deleted from our servers. There's no inbox, no archive and nothing to scroll back through.
That cuts both ways. Nobody can read it back later, including you. If you need a record of something, The Line is the wrong place for it.
The service still keeps what it needs to run, such as your account, your settings and who you've blocked. The privacy policy lists exactly what, and for how long.
Connect your way
No phone number, no email, no password. You get a temporary handle like @line7k2wq and can be reached at it right away.
It's temporary. Delete the app or choose start fresh and it's gone for good. Leave the app closed for a long time and it can be released to someone else.
Register a number to make your identity yours. It stops being disposable, people who already have your number can find you, and you can pick a @username and add a recovery email.
Started anonymously? Add a number later and keep the handle you already have.
One field. Type any of these and tap the result to ring them.
An empty search shows the people this phone has been on a line with. The list lives on your device, holds no conversation content, and can be cleared in Settings.
It's a quick way to ring someone again. It won't bring back what you said.
Type their full number. If they aren't on The Line, you can send them an invitation with a link to get the app.
Privacy and control
Conversation text isn't kept once the line closes. A report never contains what anyone typed, because there's no transcript to attach.
Use The Line without a phone number. Nobody can browse a directory of users. People find you by a name, number or code they already have.
Report from an incoming line, a live line, or anyone you've looked up, and a person reviews it. A blocked account can't ring you.
Account → delete account, inside the app. Your directory record, handle, phone registration and push tokens are removed from our servers.
Text is encrypted on the way and while it passes through, but it isn't end-to-end encrypted. Treat The Line like a text message, not a vault for secrets.
