End User Licence Agreement — Readers & Digital Content
This licence applies to the graded readers, pinyin annotations, word lists, narration audio, illustrations and related tools made available through mandarinmiles.com by David Yuan, an individual based in mainland China. By accessing purchased content you accept this licence. Your statutory consumer rights, including the refund and withdrawal rights, are not affected.
1. What you may do
- Read and listen to the content for your own learning, or for teaching a single class or one household under a family or classroom plan.
- Print limited extracts as classroom handouts for the students covered by your licence.
- Save words and track your own progress in your account.
2. What you may not do
- Redistribute, resell, sublicense, publish or publicly perform the readers, audio or word lists.
- Scrape in bulk, reverse-engineer, or extract the pinyin, segmentation, frequency or audio datasets — including for building dictionaries, corpora or machine-learning or AI-training datasets — without our written permission.
- Bypass the protected audio gateway or share an account, seat or download link outside your household or class.
- Remove copyright, attribution or AI-content notices, or present AI-assisted illustrations or synthesised narration as human-created work.
Where we use third-party open data (for example CC BY-SA 4.0 material listed on our Credits page), that licence continues to apply to the underlying data and requires attribution and share-alike for modifications. Our own reader texts and compilation remain our work.
3. AI-assisted and synthetic material
Some illustrations are AI-assisted and reviewed before publication; narration is text-to-speech. Our approach, labelling and limitations are described in the AI Content Disclosure. We do not grant rights in third-party generative tools or their models.
4. Availability and termination
Access continues for the duration of your purchase or active subscription; one-time purchases are licensed for continued personal access while the service operates. We may suspend or terminate access for a material breach of this licence or to protect the service and other users, with notice where appropriate. On termination your statutory refund rights remain governed by the Refund & Withdrawal Policy.
5. Warranty
Content is provided for learning and is not a certified assessment of proficiency; level labels are guidance, not a formal qualification. To the extent permitted by law the content is provided “as is”, without affecting mandatory consumer guarantees for digital content or the Terms of Service.
