Nybble - Encrypted Chat

Your messages are encrypted on your device. The keys stay with you; the server only ever carries unreadable bytes.

Nybble is a private messenger built on end-to-end encryption. Your messages are encrypted on your device — the decryption keys never leave your phone, and our servers only ever carry unreadable bytes.

• End-to-end encrypted 1:1 and group chats (X3DH + Double Ratchet) • Text, photos, voice messages and stickers • Voice and video calls • Stories • Reply, forward, edit, reactions and read receipts • Encrypted iCloud backup, so reinstalling doesn't lose your history • Find friends by phone number — or stay hidden and be found by @username only

The server never sees your message content. Notifications reveal only what you choose. Privacy is the default, not a setting.

Report and block are available on every profile and every message. We have zero tolerance for objectionable content and abusive users, and review reports within 24 hours. Terms of Use: https://nybble.app/terms.html
