Is Typewriter safe?

Clean risk

Typewriter reads key presses on visited pages and forwards key codes inside the extension to play typing sounds.

Typewriter injects a content script on all websites that listens for non-Ctrl key presses and sends each key code to the extension's background worker. The background worker forwards those key codes, along with sound settings, to an offscreen audio document that plays bundled MP3 typing sounds. The reviewed code and claim do not show those key codes being sent to an external server.
