Frequently Asked Questions

Is HSK One officially affiliated with the HSK exam?

No. HSK One is independently developed. We align our content with the published HSK syllabus but have no official partnership with CTI or Hanban.

Will core features always be free?

Yes. Lessons, exercises, flashcards, and mock tests are free by design. Future paid features will only add convenience (AI tutoring, offline), never gate core learning.

Can I use HSK One content in my classroom?

Personal and small-group educational use is fine. For bulk redistribution or commercial use, contact us first.
