Is Mochi Dictionary Extension safe?

Medium risk

Mochi Dictionary Extension ships a static Mochidemy API key used for dictionary and profile API requests.

The content script and service worker attach the same hardcoded privateKey value when calling Mochidemy API hosts. Those calls include dictionary lookups and profile-related requests, with code pointing to mochien-server-release.mochidemy.com and mochien-server.mochidemy.com.
