VocabularyStream User Agreement

View the Chinese version

This User Agreement applies to VocabularyStream, also presented as the App. By downloading, accessing, or using the App, you agree to this Agreement.

1. The App

VocabularyStream is an English-vocabulary learning app. It provides word cards, vocabulary lists, pronunciation playback, local learning settings, and related study features. Learning content is for general educational reference and does not guarantee a particular examination, score, translation, or learning result.

The App does not require a user login or developer-operated account. Learning state, selected lists, and settings are kept on the device. The App may download public vocabulary manifests and vocabulary files through HTTPS to refresh learning content; it does not upload your learning state to the developer.

2. Use of the App

You may use the App for lawful personal learning. You must not interfere with the App, bypass purchase checks, misrepresent a transaction, or copy, distribute, sell, rent, reverse engineer, or commercially exploit the App or its curated content except where applicable law permits it.

Users and, where applicable, their parents or guardians should use the App and make purchase decisions in accordance with applicable law.

3. Apple Purchases and Restore Purchases

The App offers two U.S. plans through Apple StoreKit with the same Pro features: an annual auto-renewable subscription for US$14.99 per year (com.lyz.VocabularyStream.pro.yearly) and a lifetime non-consumable purchase for a one-time US$59.99 (com.lyz.VocabularyStream.pro.lifetime). Lifetime access has no automatic renewal. Product availability, the final price, currency, renewal period, and included features are those shown by Apple before purchase.

  1. Apple processes payment, renewal, cancellation, and refunds under Apple's own terms and policies.
  2. An auto-renewable subscription continues according to the period shown in Apple's purchase interface unless you cancel it through your Apple Account subscription settings.
  3. Deleting the App does not cancel an Apple subscription. Purchasing lifetime access does not automatically cancel an existing annual subscription; cancel that subscription in your Apple Account subscription settings to prevent further renewals.
  4. After reinstalling the App or changing devices, you may use Restore Purchases to ask Apple to recheck eligible purchases.

4. Content and Availability

We may correct, supplement, remove, or adjust vocabulary content and App features to improve accuracy, learning quality, security, or compatibility. Network availability, device storage, system behavior, Apple services, and other circumstances may affect access to some features.

5. Intellectual Property

The App's software, interface, selection and arrangement of content, and related materials are protected by applicable intellectual-property laws. This Agreement does not restrict the use of general language facts, but it does not grant rights to copy the App's software, presentation, or curated compilation beyond lawful personal use.

6. Disclaimer and Liability

We make reasonable efforts to keep the App functional and its learning content useful, but do not promise that the App will be uninterrupted, error-free, or suitable for every individual purpose. Nothing in this Agreement excludes rights or liabilities that cannot be excluded under applicable law.

7. Changes and Contact

We may update this Agreement when the App, applicable rules, or Apple platform requirements change. The current online version will show its last-updated date.
