Last updated: July 5, 2026 最后更新：2026年7月5日
1. Product and purchase model 1. 产品与购买模型
Puffy is sold as a one-time software license. Checkout never enrolls you in a recurring plan. Puffy 采用一次性授权销售。结账不会让你加入任何周期扣费计划。
2. License and acceptable use 2. 授权与使用
Once payment clears, you get access to what you bought. Reselling licenses, abusive sharing, and reverse engineering are not allowed. 付款完成后，你就获得所购范围的使用权。禁止转售授权、滥用共享和反向工程。
3. Payments and account controls 3. 付款与账户控制
Payments are handled by our payment provider, and card details never reach us. If a purchase shows fraud or abuse, we can limit or suspend that license. 付款由支付服务商处理，银行卡信息不经过我们。如果某个购买出现欺诈或滥用，我们可以限制或停用对应授权。
4. Trial and refunds 4. 试用与退款
Puffy offers a 5-day free trial before purchase and a 7-day no-questions refund window after purchase. To request a refund, email support@nxsio.com with your order number. Your local files are unaffected either way. Puffy 提供购买前 5 天免费试用和购买后 7 天无理由退款。申请退款时把订单号发到 support@nxsio.com 即可。无论退不退，你的本地文件都不受影响。
