1. Digital product notice / 数字商品说明
License keys, authorization credentials and activated software access are digital products. Once a digital product has been delivered, activated or bound, it generally does not support an unconditional no-reason refund, except where mandatory law or a payment platform rule provides otherwise.
卡密、授权凭据和已开通的软件服务属于数字化商品。数字商品一经交付、激活或绑定，通常不支持无理由退款；法律或支付平台有强制规定的除外。
2. Eligible support cases / 可申请售后的情形
For duplicate charges, confirmed payment without delivery, a technical failure that prevents use, or a material mismatch with the purchased plan, contact support promptly. After verification, we may repair, re-deliver or refund as appropriate.
如发生重复扣款、支付成功但未交付、技术故障导致无法使用，或实际服务与购买套餐明显不符，请及时联系客服。经核实属于平台责任的，我们会视情况修复、补发或退款。
3. Non-refundable cases / 通常不支持退款的情形
Refunds generally do not apply where the wrong machine code or email was entered, the license was transferred or disclosed, part of the service was used, the terms were violated, the device environment is incompatible, or the user simply changes their mind.
因用户输入错误机器码或邮箱、主动转让或泄露授权、已使用部分服务、违反服务条款、设备环境不兼容，或个人原因不再需要等情况，通常不属于退款范围。
4. How to request support / 申请方式

5. Review and legal rights / 核验与法定权利
The result is based on order verification, payment-channel rules and applicable law. Nothing in this policy limits a consumer right that cannot legally be waived.
退款结果以订单核验、支付渠道规则和适用法律为准。本规则不限制消费者依法享有的不可排除权利。
