How it works

You meet, and then you connect.

Two ways in, and both need a person. Everyone else has no route to you.


How you connect

Two ways in.

In person, or through someone you both trust.

The door

Nothing above the line arrived from someone who was not let in. There is no path for it to take.

Two ways in, and one way nowhere. The third row is not a filter deciding what to show you. There is no route for it to take.
The Door

Show this to the person in front of you. Their phone scans it, both of you accept, and the line between you exists.

My codeScan

In person. Physical presence is the ceremony. It cannot be botted, bought or farmed.

Introduction from SarahMom, this is Nik, my neighbour from upstairs. Nik, this is my mother. Before you acceptSarah vouched for Nik. Ask him something only he would know.
AcceptNot now

Introduced. Someone you both trust hands over the real keys, over lines that are already encrypted.

Unknown senderAttempting to reach you

There is no screen for this. A person you have not accepted cannot address you, so nothing arrives to approve, ignore or read.

No requests

Everyone else. Not a blocked message. Not a spam folder. No delivery at all.

SarahMom, this is Nik, my neighbour from upstairs. He is fixing the roof leak.Sent to both of you NikHello! Sarah gave me your Idy. I can come by on Thursday morning.

Sarah vouched for Nik.

She has met him in person. Ask him something only he would know before you accept.

Vouching

The people you trust are the directory.

No lookup by name or number. To reach somebody far away, a mutual contact introduces you.

Groups

Nobody adds you to anything.

You have been put into a group you never asked to join, where everyone could see your number. That does not happen here.

Sarah invites you to "Street party"

14 members. Joining lets you post here. Nobody in it can message you privately.

Being in a room with forty people does not have to mean forty people can reach you.
One line per person

Every connection has its own switch.

Accepting someone does not put you on a list. It creates a single private line between the two of you, and that line answers to you alone.

Pause

Held quietly at our relay. Nothing is delivered and nothing is lost.

Block

The line stops carrying anything at all, in both directions.

Delete

The line is gone. Reaching you again means meeting you again.
