Is Zaplyn safe?

Clean risk

Zaplyn sends WhatsApp Web voice notes to external servers for transcription and audio conversion.

On web.whatsapp.com, when a user transcribes a voice note, the extension downloads the audio and sends it base64-encoded to a speech-to-text service. Recorded audio is also posted to an audio conversion service. It additionally loads the CSS selectors it uses to drive the WhatsApp Web interface from a remote JSON endpoint on each load.

Where it sends data

Destinations our analysis observed Zaplyn 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.
