one line. two people.

mono isn't built to connect you to everyone. it's built for one line, with one person — fully private, fully encrypted.

everything mono leaves out — on purpose.

// the part that matters

hand someone your phone and open mono — no name, no profile photo, no phone attached, no history, no hint of who's on the other line. only you know who you're talking to.

// honestly

Is mono an alternative to WhatsApp, Telegram, Snapchat or Signal?

Not exactly. Those are full messengers you use every day. mono is for that conversation — encrypted, 1-to-1, with no history and no trace. Different jobs — you can keep them all.

A private chat without an account?

Yes. No name, no email, no phone. Nothing to register.

Can a stranger find me?

No. No matchmaking, no discovery, no public directory. No one reaches you unless you shared your key.

Messages that disappear?

Only the last 15 stay visible, and after 36 hours of inactivity the whole conversation is permanently deleted for both.

Is it a group chat?

No. One conversation at a time. Just two people.
