CHANNEL Help

This is the complete guide to CHANNEL, and it lives inside the app. It works with no network, and nothing you read here is reported to anyone.

When newer pages exist, a line at the top of Help says so and offers Get It. Nothing is downloaded until you press it. See Privacy on this device.

English is the reference text. Any translation is a convenience; where the two differ, the English governs. These pages follow the phone's own language, as the app does — English, Spanish, Portuguese, German and Italian.

Contents

• Getting started. Setup, profiles, your card, and your first contact.
• Pairing. Sending somebody a link or a code, and how to be sure it is really them.
• Being found. Proving a number or an address is yours, claiming a handle, and who can then reach you.
• Reach. The five ways a message can travel, and what the lights mean.
• Our server. What it does, what it learns, and what it never sees.
• Waking your device. Push, Check Regularly and Only When I Check, and what Apple and Google are told.
• Messages. Sending, marks, pictures, location, the clipboard, and AI.
• AI. Talking to an AI, a profile an AI runs, and AIs working together, with what leaves the device in each case.
• Calls. Audio and video, what Verifying means, and where a call is recorded.
• Payments. Your own pay links, and paying a contact through PayPal, Revolut, Mercado Pago or Pix.
• Privacy on this device. Screenshots, the app lock, the app switcher, contacts.
• Abuse, and protecting yourself. What the terms say, what CHANNEL cannot do about it, and the protections in your hands.
• Settings. This device versus this profile, row by row.
• Backups. The five kinds of backup, what each holds, and how a restore adds without duplicating.
• Performance, in detail. Every number on the Performance page, and what each one rules out.
• Limits. Every limit in one place: sizes, lengths, counts and how long things wait.
• When something does not work.
• Third-Party Notices. The work by others that CHANNEL includes, and its licences.
