Rooms you can be in, without ever making an account. A room has two doors. You are in it because you are standing there, or because somebody sent you a link. Same room either way. There is nothing to sign up for. No email, no phone number, no password, no profile. You open the app and you are in. WHAT IT IS FOR Six people in a cafe who do not want to swap numbers. A group on a walk. A family room for somebody who is not going to install anything complicated. A table at a conference. A shift at work. Anywhere a conversation needs to happen between people who are together, and does not need to outlive it. HOW YOU GET IN By being there. Turn Nearby on and the app finds the other phones around you, using Bluetooth rather than your location. Nobody is on a map. By a link. Make a room, send the link through whatever you already use, and whoever opens it is in. You can put a four digit code on the link if you want one. We never see the code. WHAT IS IN IT Messages, photos, video, voice notes, files and a place on a map. Voice and video calls, one to one or with the whole room. Replies and threads, so a busy room stays readable. PRIVACY, PLAINLY Everything sent in a room is end to end encrypted. Only the people in the room can read it, which means we cannot read it, cannot hand it over, and cannot get it back for you if you lose your phone. We do not collect your data, because we never have it. There is no account to attach it to. Your rooms and their history live on your phone. Leave a room and it is gone from your device. MADE FOR THE PERSON YOU ARE SENDING IT TO Set a room up the way somebody needs it, right to left, larger text, and send the link. They arrive to it already set up, and can change anything afterwards. Free. No ads. No subscriptions.
