Is Speech Translator safe?

Low risk

Speech Translator exposes an embeddable popup that starts speech recognition and sends transcripts to Google Translate.

The extension makes its popup page available to all sites, and that page starts Chrome speech recognition as soon as it loads. After microphone permission exists or is granted, recognized speech is translated through translate.googleapis.com by default; optional proxy and streaming modes can send transcript and translation data to KappaFlow endpoints.

Where it sends data

Destinations our analysis observed Speech Translator 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.
