Is ZappSeller safe?

Clean risk

ZappSeller adds sales tools to WhatsApp Web and uploads voice messages you choose to transcribe to hiperchat.com.br.

ZappSeller runs on web.whatsapp.com and adds seller features to the chat page. When you click the transcribe button on a voice message, it downloads the audio and sends it, base64-encoded, to a speech-to-text server at hc-stt.hiperchat.com.br. The upload only happens on that click.

Where it sends data

Destinations our analysis observed ZappSeller contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
