可以申请。未生成且 AI 写作辅助使用少于 5 次的订单，通常可自动退款；已经生成、大量使用辅助或涉及部分退款的订单需要人工审核。重复扣款、权益未到账和明确技术故障会优先处理。请优先从「我的订单」申请，完整规则见退款政策。

不会。 我们不将您提交的答案或自然语言文本用于模型训练。登录状态下，为支持跨设备查看和重新生成，生成结果与必要的答题、校准信息会保留至您删除对应记录或注销账户；临时数据按功能需要保留。详见隐私政策。

UI 目前中文 / 英文双语；内容会用您问卷填写的语言生成。中文输入 → 中文结果，英文输入 → 英文结果。混合语言的质量可能下降。

先检查网络。若开始生成后超过 5 分钟仍卡在“生成中”页面，请从「我的订单」申请处理，或写信至 support@airrapp.com 并附上订单号、登录方式和设备信息。我们会人工排查，并按实际情况恢复权益或退款。

可以。登录状态下生成完成后，同行书正文、深度附件及用于重新生成的答题与校准信息会同步至账户；用同一账号登录，即可在「历史记录」中查看或重新生成。编辑过程中的原始草稿不会上传。未登录时，结果只保存在当前设备浏览器中，换设备无法找回。

付款成功后，微信支付、支付宝、Gumroad 或对应支付平台会提供订单记录或收据。若需要协助核对订单，邮件 support@airrapp.com。

本服务不面向 14 周岁以下用户；未满 18 周岁请在监护人同意下使用。

You may request one. Orders with no generated result and fewer than five AI writing-assistance uses normally qualify for automatic refund; generated, substantially used, or partially refunded orders require review. Duplicate charges, missing entitlements, and clear technical failures receive priority. Use “My Orders” where available. Full rules: Refund Policy.

No. We do not use submitted answers or free-form text for model training. For signed-in users, generated content and the answers and calibration needed for cross-device access remain until the related history is deleted or the account is closed; temporary data is retained only as needed for the relevant function. See the Privacy Policy.

UI is bilingual zh/en. The result is generated in whichever language you answered in. Mixing languages may degrade quality.

Check your network first. If generation remains stuck for more than five minutes after it starts, use “My Orders” or email support@airrapp.com with your order ID, sign-in method, and device details. We will investigate and restore the entitlement or refund as appropriate.

Yes. After a signed-in generation completes, the letter, deep attachment, and answers and calibration needed for regeneration are synced to the account. Sign in with the same account and use “History” to view or regenerate it. Raw editing drafts are not uploaded. When signed out, the result remains only in that device's browser and cannot be recovered on another device.

WeChat Pay, Alipay, Gumroad, or the relevant payment platform provides order records or receipts after successful payment. For order-support help, email support@airrapp.com.

The Service is not directed at users under 14; users under 18 should use it with guardian consent.
