What Zam Zam does.

A clear list of what is in the product. If something is not here, we are not advertising it.

The conversations people use every day.

  • Direct chats

    A private conversation between two accounts. Always end-to-end encrypted.

  • Groups

    Group messages are end-to-end encrypted by default.

    A chat with yourself, encrypted to your devices.

  • Replies, reactions, editing

    Reply to a message, react, or edit one you sent.

  • Delete and forward

    Delete for yourself or for everyone. Forwarding sends the message on.

  • Pins, archive, mute

    Pin a message, archive a chat, mute it, or mark it unread.

  • Search

    Search for people, groups, and channels. Message search runs on the device.

Media

  • Voice messages

    Record and send a voice message.

  • Files

    Send a file.

Calls

Voice and video, with different encryption for one-to-one and group calls.

    Voice and video, encrypted between the people on the call.

  • Group calls

    Group call media is end-to-end encrypted by default.

    A group call can require approval before someone joins.

  • Incoming calls

    The apps can present an incoming call when the system allows it.

    Desktop and Android. Not available on iPhone.

Privacy

Controls that exist in the product today.

  • End-to-end encryption

    Private conversations are encrypted by default. Read the security page for the limits.

  • Last seen and profile photo

    Each can be everybody, people you chat with, or nobody.

  • Read receipts

    On by default, and only mutual.

  • Block and report

    Block a person, or send an abuse report.

Communities

Groups and channels, without a separate business product.

  • Admins

    Owners and admins manage members. Ownership can be transferred.

  • Invite links

    Join a group or channel with a link.

  • Public channels

    A public channel can be found and subscribed to. It is not end-to-end encrypted.

Multi-device

More than one signed-in device, each with its own keys.

  • Sign in again

    Another phone or computer is added by signing in. QR linking is not available.

  • A new device sees new messages

    It can read messages sent after it joins. Older encrypted history is not restored from a backup.

  • Remove a device

    Revoke a device you no longer use. Its sessions end, and encryption moves forward without it.

  • Shared settings

    Privacy and notification settings belong to the account. Drafts stay on the device you typed them on.

Stories

Short updates, not a second messaging system.

  • Photo, video, or text

    Post a story for people you already talk to.

  • 24 hours

    Stories expire after a day.

  • Not end-to-end encrypted

    Story text is stored so it can be delivered. There are no story replies yet.
