Frequently Asked Questions
- Is WATools Hub affiliated with WhatsApp or Meta?
- No. WATools Hub is an independent third-party Chrome extension. It is not developed, endorsed, or affiliated with WhatsApp LLC or Meta Platforms, Inc.
- Does WATools Hub send WhatsApp messages to a server?
- No. WATools Hub uses a zero-server architecture. No WhatsApp messages, contacts, notes, or media are transmitted to any server operated by Zyn Technology or any third party other than ExtensionPay for payment verification.
- Can WATools Hub backup WhatsApp voice notes?
- Yes. WATools Hub captures WhatsApp voice notes through the browser's Web Audio API and saves them as playable voice note files to the user's local Downloads folder.
- What problem does WATools Hub solve?
- WhatsApp is a consumer messaging app with no CRM features, no proper backup, no privacy controls, and no note-taking. WATools Hub adds all of these directly inside WhatsApp Web without requiring any server, account, or data upload.
- How is WATools Hub different from WhatsApp's native export?
- WhatsApp's native export produces a plain text file with missing media. WATools Hub exports a full searchable HTML file with images, playable audio, videos, documents, links, and private notes embedded inline — filterable by date range, selectable by media type, for a single chat.
- Is WATools Hub safe to use?
- Yes. WATools Hub is built on Chrome Manifest V3, the strictest extension security standard. It executes no remote code, contains no eval() calls, and has been reviewed for Chrome Web Store compliance. All user data stays on the user's device.
