Is DuoNinja - Dual captions for YouTube videos safe?

Clean risk

DuoNinja sends imported Duolingo vocabulary rows to its own API when you choose to import them.

On Duolingo word-list pages, DuoNinja adds an import button that scrapes visible word and translation rows only after you trigger the import. It then creates a DuoNinja deck and sends the word and translation pairs to DuoNinja's bulk card API.
