Who Cloak Dagger is for

Built for conversations where exposure has consequences.

Cloak Dagger is a deliberate choice for people whose communications carry real professional, legal, or personal stakes — not a status symbol.

  • Executives & founders

    Decisions that move markets and reputations.

  • Family offices

    Discretion across principals, family, and staff.

  • Legal teams

    Client work that demands confidentiality.

  • Journalists

    Sources that must stay protected.

  • Security teams

    Operations where timing and privacy matter.

  • Private organizations

    Teams that outgrew consumer messengers.

  • Private messaging
  • Private groups
  • Cloak Dagger Circles
  • Cloak Dagger IDs
  • Trusted devices
  • Disappearing conversations

Groups & Circles

Private groups. Trusted Circles.

Organize trusted people into private groups without creating a public community, follower graph, or discoverable social network.

A person can belong to a Circle without automatically seeing every group inside it. Cloak Dagger organizes trust — it does not create a public social network.

  • Invite-only
  • Controlled membership
  • Group-level permissions
  • Security policies
  • Local-first intelligence
  • No public discovery

Example Circle

Family Office

InvestmentsGroup 4

Membership is granted by the Circle owner. No open invitation links, no discovery, no follower graph.

Cloak Mode

Reduce exposure. One control.

When someone else can see your screen, Cloak Dagger should reveal less. One control reduces notification details, hides activity information, and locks selected conversations.

  • Screen sharing
  • Travel
  • Handing your device to someone else

Dagger

When you stop trusting the device.

Dagger is Cloak Dagger's emergency device control. Activate it to destroy local Cloak Dagger keys, clear sensitive local data and revoke the device from your account. Your other trusted devices and Cloak Dagger membership remain active.

  • Destroy local keys

    Cloak Dagger removes the keys required to use local encrypted data.

  • Clear private local data

    Messages, AI memory, indexes and Cloak Dagger-controlled sensitive caches are cleared.

  • Revoke the device

    The device loses access to your Cloak Dagger account.

Hold to Dagger

Dagger removes Cloak Dagger-controlled local data and device authorization. Operating-system or browser artifacts outside Cloak Dagger's control may remain.

Cloak Dagger AI

Your AI should not need your conversations in the cloud.

The model does not search your entire message history. Cloak Dagger retrieves only the context permitted for the request.

01

Retrieve locally

Only permitted context is selected.

02

Reason locally

Cloak Dagger AI runs on the device where supported.

03

Show the boundary

Cloak Dagger tells you whether processing stayed local.

Local processing is the default. Cloud fallback can be disabled completely and must never occur silently.

Trust

Security should be inspectable.

Cloak Dagger does not ask you to trust a slogan. Its security model, processing boundaries, and known limitations are clear enough to inspect.

Communication resilience · beta

Stay connected when the internet is unavailable.

Cloak Dagger Nearby beta lets trusted users share encrypted text over a local Wi-Fi network or phone hotspot. It uses direct peer connections and Cloak Dagger’s existing end-to-end encryption.

Cloak Dagger Nearby

A local route for trusted teams.

Designed for travel, remote operations, executive protection, network outages and private sites. Everyone must share the same local Wi-Fi or hotspot; this does not provide unlimited range.

  • Shared local Wi-Fi or phone hotspot
  • Normal internet access is not required for the local route
  • Message content remains protected by Cloak Dagger E2EE
  • Internet synchronization and delivery recovery are included in the beta; current scope is trusted one-to-one text chats

Coming later

Cloak Dagger Local Relay

A dedicated local communications layer being explored for executive protection, remote operations, private sites and high-assurance deployments. Local communication is designed to continue when external networks are unavailable.

The Local Relay is not currently available. No purchase or availability claims are being made.

Identity

Control who knows you and which devices you trust.

No public phone-number identity. Cloak Dagger IDs, explicit verification, and device control keep the edges of your network deliberate.

01

Cloak Dagger ID

Share a private identifier instead of publishing a phone number.

02

Verify

Confirm identity in person using QR verification.

03

Devices

See and revoke every authorized device.

Ghost Chats

Some conversations should disappear.

Set conversations to disappear automatically after the period you choose — with a quiet clock rather than theatrics.

  • Timers you choose

    Conversations are configured to disappear from Cloak Dagger after the period you set.

  • View-once media

    View-once media can be opened once inside Cloak Dagger.

  • No AI memory by default

    Ghost Chats are excluded from Cloak Dagger AI memory unless you allow it.

  • Local retention controls

    History rules live on your device and follow your settings.
