You're correct, it uses Google Translate to generate the in-line translation, and offers a more in-depth translation from wordreference.com in a sidebar (for the language pairs it supports). I find the Google Translate result good enough to get the meaning the vast majority of the time, which is enough to enjoy reading. When you start to learn each word, it's very much encouraged to verify and edit each translation the first time the flashcard appears. I agree that blindly accepting and learning the google translate results would be a very bad idea. I'll also investigate different dictionaries and translation services as the project progresses.
