READ. TRANSLATE. UNDERSTAND.
译读与练习
译读由 Yongdong Wang 提供，用于语言学习。你保留对自己内容的权利，并应只导入及分享有权使用的材料。请勿利用服务实施侵权、绕过订阅或安全限制、批量滥用接口，或干扰他人正常使用。
在线反馈
AI 的批改、释义和水平评估可能不准确。它们是学习参考，不是考试认证或专业意见。在线功能需要联网并授权内容处理，受合理的安全和使用限制；服务暂时不可用时，你的本地译文仍会保留。
订阅与付款
A1/A2 短读批改免费。译读 Pro 月度和年度订阅提供同样权益：导入文档及 B1–C2 短读的在线批改和讲解。实际价格、币种和周期以购买前的 App Store 确认页面为准；年度方案按年一次收费。
订阅通过 Apple 付款并自动续订，除非在当前周期结束至少 24 小时前取消。可在 iPhone“设置 → Apple 账户 → 订阅”管理或取消。删除 App 不会取消订阅。购买页面提供“恢复购买”。退款可通过 Apple 报告问题申请，适用 Apple 的政策。
适用条款
App 的使用许可适用 Apple 标准最终用户许可协议（EULA）。本说明补充服务用途和订阅信息，不限制你依法享有的权利。数据处理见隐私政策。问题请联系 wandernovainc@gmail.com。
Use of Yidu
Yidu is a language-learning service provided by Yongdong Wang. You retain rights to your content and should only import and share material you are entitled to use. Do not infringe others’ rights, bypass subscription or security controls, abuse the API or disrupt the service.
AI feedback
Feedback, meanings and level estimates can be inaccurate. They are learning aids, not exam certifications or professional advice. Online features need an internet connection and permission to process content, and are subject to reasonable security and usage limits. Local drafts remain available during temporary service outages.
Subscriptions
A1/A2 short-reading feedback is free. Monthly and annual Yidu Pro plans provide the same access: online translation feedback for imported documents and B1–C2 short readings. Price, currency and period are shown before purchase in Apple’s confirmation screen; the annual plan is billed once per year.
Apple handles payment. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel in iPhone Settings → Apple Account → Subscriptions. Deleting the app does not cancel a subscription. Restore Purchases is available in the app. Request refunds through Apple under its policies.
License and contact
The app is licensed under Apple’s Standard EULA. This notice explains service and subscription details without limiting your statutory rights. See the Privacy Policy or contact wandernovainc@gmail.com.
