What do I actually get?
A downloadable A4 PDF (~260 pages), a browser-based flashcard app, an Anki deck (.apkg), and a full audio library with native recordings — all for the same level and language pair. Everything is yours to keep.
Do I need an account to buy?
No. Just click "Buy now", pay via Stripe, and we'll email you a magic link to access your personal library. No password, no sign-up form. If you buy again later, the new book is added to the same account automatically.
Can I get a refund?
Yes — before you download anything. Email hello@huaflow.com and we'll refund you, no questions asked.
