Nuco is a private 1:1 messenger built around one idea: no one but you and the person you are talking to should be able to read your messages. Not us, not the server, not anyone who takes the device. Every message is sealed on your device by libsignal, the engine behind the Signal Protocol, with post quantum key agreement (PQXDH): even someone recording your traffic today gains nothing from a future quantum computer. A message can only be opened on your device and your contact's device. The relay that carries your messages is untrusted by design: it only ever sees unreadable ciphertext, and it never holds a key that could decrypt anything. Why people choose Nuco: - End to end encryption on every message, with in person verification so you can confirm you are really talking to your contact. - Disappearing messages: set a timer and messages delete themselves from both devices. - Screenshot protection: agree with your contact to block screenshots and screen recording in a chat, on both devices. - On device only: your history lives in an encrypted database on your phone. There is no cloud backup to leak or subpoena. - App lock: unlock with Face ID, Touch ID, or a PIN. Locking closes the encrypted database and drops the key from memory, so a locked phone reveals nothing. - Content free notifications: a generic new message banner that never sends the text or the sender through Apple. - Private voice calls: end to end encrypted 1:1 calls that ring on your lock screen, always routed through a relay so the person you call never learns your IP address. - No accounts tied to you: no phone number, no email, no real name required. - No ads, no analytics, no trackers. Nuco is deliberately small and focused. Add a contact by scanning their code in person, verify you match, and start a conversation that stays between the two of you.
