Is BYS Convert safe?

Low risk

BYS Convert uploads WhatsApp Web voice messages to hc-stt.hiperchat.com.br for transcription.

On web.whatsapp.com the extension adds a transcribe button next to audio messages. Clicking it downloads the audio and sends it, base64-encoded, to a Hiperchat speech-to-text server. A bundled WhatsApp helper also sends links in outgoing messages to third-party link-preview servers to fetch thumbnails.

Where it sends data

Destinations our analysis observed BYS Convert 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.
