Is Autolingo safe?

Autolingo exposes its Chrome extension ID to Duolingo page scripts through a page event bridge.

When Autolingo is enabled on Duolingo, it injects a page script and uses CustomEvent messages to coordinate with its content script. That bridge responds to a page event by publishing the extension runtime ID, so scripts running in the same Duolingo document can read that identifier. The reviewed claim does not show user data being sent to an external service.
