Communication Modes

Choose how each Hat communicates.

Use Stealth, Normal or Broadcast to set the communication posture of a Hat. Keep client conversations and announcements in the mode that fits the job.

No phone number or email required for core Hat use.

City of Hats · Communication Modes

The useful difference

A clearer way to handle sensitive work.

01

Normal

Use the ordinary conversation mode for everyday exchanges within a Hat channel.

02

Stealth

Choose the quieter posture offered in the app when you want to limit visible activity.

03

Broadcast

Use the supported broadcast workflow for one-way announcements. Plan and client requirements apply.

How it works

Three deliberate steps.

01

Choose a Hat

Open the identity you want to configure.

02

Review the available modes

Select the communication mode offered by your app and plan.

03

Communicate deliberately

Check the selected mode before starting a conversation or publishing an announcement.

Know the boundary

Choose controls with clear expectations.

Presence controls do not make activity invisible to all networks or service infrastructure. Hat channels and external integrations have different encryption and metadata boundaries.

Review the security evidence

Questions, answered

Before you get started.

Where can I use Communication Modes?

Open City of Hats to review the controls available for your client, content and plan. The app shows applicable requirements before you proceed.

What should I check before sharing sensitive information?

Verify the recipient, use a supported device and choose appropriate access and retention rules. Review the Security Evidence Center for boundaries and evidence status.

City of Hats is free to use. Feature availability and limits vary by plan and client. Premium is optional; review current limits in the app or on the plans page.
