WhatsApp Chat Export per Walter IT-Services

ChatBeweis turns a WhatsApp chat into a document, not a screenshot.

The extension exports the chat currently open in WhatsApp Web as PDF, TXT or CSV. In evidence mode it produces a document you can hand over without having to explain it: a cover sheet, a sequential number for every message, an attachment index for images, and a SHA-256 checksum over the content – for your lawyer, a rental dispute, or correspondence with your landlord.

YOUR CHATS STAY ON YOUR COMPUTER
All processing happens locally in your browser. Neither text nor images ever leave your device – not in full, not in part. The free version works entirely without any network connection. In the Pro version, the extension checks with the license server at most once a day to confirm your key is still valid; the only thing transmitted is the license key itself. The extension's security policy technically allows exactly this one connection – Chrome itself blocks any other.

FREE AND PRO
Free: unlimited TXT export. Pro (one-time purchase, no subscription): PDF and CSV export plus evidence mode with cover sheet, numbering, attachment index and checksum.

WHAT THE EXTENSION DOES NOT DO
No accounts, no telemetry, no tracking. It only reads the chat you have opened, and only when you export.

Notes: Not an official WhatsApp product; WhatsApp is a trademark of Meta Platforms, Inc. The extension does not provide legal advice; whether an export is admissible as evidence depends on the individual case.
