About Us & Editorial Standards

1. Origin & Purpose

WhatsApp Channels were launched globally as a one-to-many broadcast feature, but Meta provided no native export or backup mechanism for followed channels. Traditional WhatsApp backup tools only handle standard individual and group chats in the "Chats" tab. When users seek to archive business communications, news updates, market alerts, or community records from the "Updates" tab, they hit a dead end.

WA Channel Exporter was engineered to bridge this gap. We created a purpose-built, open-source Chrome extension that reads broadcast channel feeds directly from WhatsApp Web, converts DOM updates into structured data (HTML, CSV, Markdown), packages high-resolution media attachments, and compiles an offline, self-contained ZIP archive.

2. Engineering Team & Expertise

KE

Open Source Maintainer & Core Developers

Specializing in client-side browser extensions, web platform APIs, and zero-telemetry architectures. With deep experience in DOM virtualization, Manifest V3 extensions, and high-performance client storage, our team designs tools that prioritize user sovereignty and uncompromising local privacy.

3. Zero-Knowledge Architecture (Our Privacy Covenant)

Unlike cloud scrapers or third-party web services that demand your session cookies or upload your messages to external servers:

  • 100% In-Browser Execution: All message scraping, media downloading, and archive compression (JSZip) execute exclusively inside your local Chrome browser session.
  • Zero Telemetry: We do not log, track, or collect your messages, channel names, subscriber counts, or phone numbers.
  • Direct Local Downloads: All files are compiled and saved directly into your operating system's local Downloads folder.
  • Open Source Transparency: Every line of code is published on GitHub under the AGPL-3.0-or-later license for community security review.

4. Editorial & Technical Accuracy Policy

WhatsApp Web receives regular background updates from Meta that alter CSS class names and DOM structures. To ensure continuous reliability and data integrity:

  • Continuous DOM Validation: We test each extension release against active production builds of WhatsApp Web to verify selector accuracy.
  • Honest Completeness Audit: Our archiver generates a manifest.json audit log with every export, detailing the exact count of captured messages, successfully downloaded media attachments, and any skipped elements.
  • Rapid Remediation: When WhatsApp Web introduces DOM schema shifts, our open-source maintainers prioritize same-week patches.
