## What is OnceChat?

OnceChat is a quiet messaging app built around a simple idea: just one
message a day.

Away from endless notifications, constant replies, and the pressure of read
receipts — you choose one message each day, carefully, and send it. That's
OnceChat.

■ One message a day
Just one message per day, taking turns. So every single letter matters.

■ Quietly gone in 24 hours
Your words fade after 24 hours. Because nothing is kept, some things become
easier to say.

■ No notifications
No push notifications, ever. Open the app when you want to, at your own pace.
A quiet place that never rushes you.

■ Today's letter
Share one short public letter a day with all your friends. Send yours, and
you can read theirs too — a new, reciprocal way to stay connected.

■ Thoughtfully secure
No passwords — sign in with a passkey (biometrics). Messages are encrypted.
No ads, and no third-party tracking.

A calm space, like the quiet before dawn. Send your one letter today, with
OnceChat.
