ZERO Chat Privado

ZERO is a private one-to-one messenger where nothing stays behind.

Messages, photos and documents are end-to-end encrypted on your iPhone, can only be viewed inside ZERO, and are erased the moment you leave the chat. Your home screen never shows message history, only your contacts.

PRIVATE BY DESIGN
- End-to-end encryption: only the person you write to can read your messages.
- No phone number, no email, no password: sign in with Apple and pick a username and photo.
- Your secret key is created on your iPhone and never leaves it.
- Contacts live only on your iPhone. There is no central contact database.

NOTHING STAYS
- Leave the chat and the whole conversation is wiped from your phone.
- The relay server only moves encrypted data it cannot read. Undelivered messages expire after 24 hours at most.

PROTECTED CONTENT
- Photos and documents (PDF and text) open only inside ZERO, with no option to save, share or copy.
- Chats, photos and documents appear black in screenshots and screen recordings, and the other person is notified when someone tries.
- Lock ZERO with Face ID or your iPhone passcode.

ADD CONTACTS IN PERSON
- Show your QR code or scan someone else's. Compare a safety number to make sure nobody is in the middle.
- Not ready to invite anyone? Try the built-in demo chat.

SAFE COMMUNITY
- Block or report any contact from the chat. Reported accounts can be suspended.
- Delete your account from Settings at any time.

Note: iOS does not allow apps to physically block the screenshot button. ZERO hides the content and warns the other person instead.
