End-to-end encrypted · No phone number
Private chat.
No number. No trace.
Talk without giving away who you are. Start a room that vanishes, keep chats with just a username, meet someone new safely, or share a private feed with your closest people. Everything is end-to-end encrypted: not even DiffWeb can read it.

Private by design
Built so we can't read your chats.
Nothing that identifies you
No phone number, no email, no contacts upload. Use a temporary room without any account, or just a username.
Safety without spying
Report anyone in one tap. Reports carry proof the messages are real, so our team can act, while everything else stays private.
Ready when you are
Your conversation.
Your rules. No trace.
Start a private room in one click, or create a free account with just a username.
