1. Information we collect / 我们收集的资料
To provide the service, we may process information you submit, such as a name, postal address, delivery email, selected template, and document settings. We also process order information such as the order number, payment network, transaction hash, payment amount, and delivery status.
For operation and security, we may record limited technical data such as IP address, request time, browser information, error details, and anti-abuse events.
为了提供服务，我们可能处理您提交的姓名、邮寄地址、接收邮箱、所选模板和文档设置，以及订单号、付款网络、交易哈希、付款金额和交付状态等订单资料。为了运行及保护网站安全，我们还可能记录有限的技术资料，例如 IP 地址、请求时间、浏览器信息、错误详情和反滥用事件。
2. How information is used / 资料用途
We use information to validate order inputs, detect payment, generate and deliver requested files, provide support, prevent abuse, diagnose errors, maintain service security, and meet applicable legal obligations.
我们使用相关资料来校验订单输入、检测付款、生成并交付所需文件、提供支持、防止滥用、诊断错误、维护服务安全及履行适用的法律义务。
3. Payment and public blockchain data / 付款与公开区块链资料
Cryptocurrency transactions occur on public blockchain networks. Transaction hashes, wallet addresses, amounts, and network activity may be publicly visible and are governed by the relevant network. sw.xuou.net does not receive or store a customer's private keys or wallet password.
加密货币交易发生在公开区块链网络上。交易哈希、钱包地址、金额及网络活动可能公开可见，并受相关网络规则约束。sw.xuou.net 不会接收或保存顾客的私钥、助记词或钱包密码。
4. Service providers / 服务提供商
We may use infrastructure, email delivery, blockchain network, security, and anti-abuse providers only as needed to operate the service. These providers process limited information on our behalf or under their own privacy terms. We do not sell personal information or share it with unrelated third parties for their advertising.
我们仅会在运营服务所需的范围内使用基础设施、邮件交付、区块链网络、安全和反滥用服务提供商。这些提供商代表我们处理有限资料，或依照其自身隐私条款处理资料。我们不会出售个人资料，也不会为了无关第三方的广告目的共享个人资料。
5. Retention / 保存期限
Information is retained only as reasonably needed for delivery, support, fraud prevention, security, recordkeeping, and legal obligations. Routine operational logs are generally rotated after 30 days, although security incidents, payment records, or support records may be kept longer when necessary.
资料仅在交付、支持、防止欺诈、安全、记录保存及法律义务所合理需要的期间内保留。常规运行日志通常在 30 天后轮换清理；必要时，安全事件、付款记录或支持记录可能保留更长时间。
6. Security / 安全措施
We use access controls, transport encryption, rate limits, and operational safeguards designed to protect service data. No internet service can guarantee absolute security, so users should not submit private keys, wallet passwords, seed phrases, or unrelated sensitive information.
我们采用访问控制、传输加密、频率限制和运行安全措施来保护服务资料。任何互联网服务都无法保证绝对安全，因此请勿提交私钥、钱包密码、助记词或与订单无关的敏感资料。

We may need to verify the request and retain limited records for security, payment reconciliation, dispute handling, or legal compliance.
您可以联系我们查询与订单相关的个人资料，请求更正不准确资料，或在法律不要求继续保留时请求删除。我们可能需要核实请求，并为安全、付款核对、争议处理或法律合规保留必要的有限记录。
