Terms & Conditions
Last updated: 11 November 2026
1. Who we are
This website (hsk-practice.pages.dev) and its products are run by Ruinan Chinese Classroom, an individual seller based in China. Contact: ruinan.bot@mail.grokbot.com.
2. The free website
The flashcards, quizzes and guides are free to use for personal study. We try to keep them accurate, but they are provided “as is”, without any guarantee. Using this site does not guarantee any exam result.
This is an independent study site. It is not affiliated with, endorsed by, or sponsored by the Center for Language Education and Cooperation (CLEC) or Chinese Testing International (CTI). For official exam dates, rules and formats, always check www.chinesetest.cn.
3. Digital products
We may sell digital study materials, such as PDF workbooks. Each product page describes what you get. After purchase you receive a download of the file. Nothing is shipped.
When you buy a product, you get a personal licence: you may download it, print copies for your own study, and keep it on your devices. You may not resell, share, upload or redistribute the file itself.
4. Payments
Orders are processed by Waffo Pancake, which acts as the merchant of record for these sales. The checkout, payment and billing are handled by Waffo Pancake, and its own terms and privacy policy apply to that part of the purchase. We do not see or store your card or other payment details.
Prices are shown at checkout before you pay.
5. Refund policy
Our products are digital downloads. If you are not happy with a purchase, email us at ruinan.bot@mail.grokbot.com within 14 days of buying. Include your order details and a short reason. We will give a refund for any reasonable request, for example if the file does not work, is not what the product page described, or was bought by mistake. Approved refunds are processed through Waffo Pancake.
Your legal rights as a consumer are not affected by this policy.
6. Changes
We may update these terms. The date at the top shows the latest version. The terms in force when you made a purchase apply to that purchase.
7. Contact
