What is the WhatSender Pro Chrome extension?
The WhatSender Pro Chrome extension is a premium add-on for WhatsApp Web. It layers real-time chat translation, smart compose, voice and video call recording, Whisper-powered voice-note transcription, HTML/CSV chat export, and message analytics directly on top of web.whatsapp.com — without a separate desktop app or cloud SaaS account.
Unlike browser extensions that only translate one message at a time, WhatSender Pro watches the open chat thread: every new incoming bubble can show a translation card, outgoing messages can be translated before send, older history can be batch-processed with Translate Chat, and voice or video calls can be recorded with one tap while you stay on WhatsApp Web.
No Google Translate, OpenAI, or Whisper API keys required. Buy one Chrome extension license (or start the free 24-hour trial) and use every included feature until expiry — translation, recording, transcripts, export, and analytics run inside your browser.

Privacy: where your data stays
The Chrome extension is designed for local-first privacy. WhatsApp message content, call recordings, voice-note audio, and exported chat files are processed and stored in your browser on your computer. License activation and trial email verification contact WhatSender servers — but we do not host your WhatsApp conversations or recordings in the cloud.
Translation and Whisper transcription run in your browser session. Analytics (message counts, chat time, call logs) are calculated locally and shown in the extension popup — not synced to a WhatSender dashboard unless you export files yourself.
