退款政策

生效日期：2026-09-26 ｜ 公司：南京德睿信息技术有限公司

本《退款政策》适用于通过本网站购买 DeruiKnow 产品与服务的订单。我们的订单由 Paddle.com Market Ltd. 作为记录商户（Merchant of Record）处理，因此退款请求同时受 Paddle 买家条款（Buyer Terms）与本政策约束。

1. 一次性软件授权

  • 本产品为数字软件产品，通过远程部署交付。若您在付款后尚未开始部署、且未获取/激活授权，可在下单之日起 14 日内申请全额退款。
  • 一旦我们已为您开始远程部署、或已交付/激活授权，鉴于数字交付的即时性，退款请求将视具体情况酌情处理，并可能扣除已发生的服务成本。
  • 若产品存在无法修复的严重功能缺陷，且我方无法在合理时间内修复，您可申请退款，我们将按未实现的价值协商处理。

2. 年度服务费（订阅）

  • 年度服务费为可选的按年订阅。您可随时取消续费，取消后不再扣取下一周期费用。
  • 已开始的年服务周期费用，因服务已按年提供，原则上不予退还；如法律另有强制规定（如消费者撤回权），则从其规定。

3. 如何申请退款

  • 通过 Paddle 付款确认邮件中的链接自助申请；或
  • 发送邮件至 deruiinfo@163.com，提供订单号（见 Paddle 收据）、购买邮箱与退款原因。
  • 我们与 Paddle 将在合理时间内处理；退款按原支付方式退回，到账时间取决于支付渠道。

4. 不适用情形

  • 已完成远程部署与验收、且产品功能正常，仅因业务效果（如 SEO 排名、转化）不满意而申请退款。
  • 违反《服务条款》（如转售、滥用）导致的终止。

5. 消费者法定权利

本政策不影响您依适用法律享有的强制消费者权利（例如欧盟/英国消费者在特定条件下的撤回权）。若当地法律赋予您更长的退款期限，以当地法律为准。

6. 拒付（Chargeback）

如您对账单有疑问，请先联系我们或 Paddle 协商解决；未经沟通直接发起拒付可能延长处理时间。

Refund Policy

Effective date: 2026-09-26 | Company: Nanjing Derui Information Technology Co., Ltd.

This Refund Policy applies to orders for the DeruiKnow product and services placed through this website. Our orders are processed by Paddle.com Market Ltd. as Merchant of Record, so refund requests are subject to both Paddle's Buyer Terms and this policy.

1. One-time software licence

  • The Product is a digital software product delivered via remote deployment. If, after payment, deployment has not started and no licence has been issued/activated, you may request a full refund within 14 days of the order date.
  • Once remote deployment has begun, or a licence has been delivered/activated, given the immediate nature of digital delivery, refund requests are assessed case by case and may be reduced by costs already incurred.
  • If the Product has a critical, unresolvable functional defect that we cannot fix within a reasonable time, you may request a refund and we will negotiate based on undelivered value.

2. Annual service fee (subscription)

  • The annual service fee is an optional yearly subscription. You may cancel renewal at any time, and no further period will be charged.
  • For an annual period already started, because the service is provided per year, the fee is generally non-refundable; where mandatory law provides otherwise (e.g. consumer withdrawal rights), that law prevails.

3. How to request a refund

  • Use the link in your Paddle payment confirmation email; or
  • Email deruiinfo@163.com with your order number (from the Paddle receipt), purchase email and reason.
  • We and Paddle will process within a reasonable time; refunds are returned via the original payment method, with timing depending on the payment channel.

4. Exclusions

  • Remote deployment and acceptance have been completed and the Product functions correctly, and the request is based only on dissatisfaction with business outcomes (e.g. SEO rankings, conversion).
  • Termination due to a breach of the Terms of Service (e.g. resale, abuse).

5. Statutory consumer rights

This policy does not affect mandatory consumer rights under applicable law (for example, the withdrawal right for EU/UK consumers under certain conditions). Where local law grants a longer refund period, local law prevails.

6. Chargebacks

If you have a question about a charge, please contact us or Paddle first. Initiating a chargeback without contact may prolong resolution.
