The tools and page layouts are written for this site. The pages make no requests to other servers (read-aloud uses your browser’s built-in voices; some browsers use online voices for this).
Third-party material
The question data are listed below with their licences. The tools use no third-party code libraries; the flashcard scheduling is our own small Leitner box routine (ts-fsrs was evaluated and not needed).
