本隐私政策阐述河南云帆电子科技有限公司（以下简称 “我们”），在您使用苹果 App Store 上的移动端应用电工计算器（以下简称 “本应用”）时，如何处理相关信息。
应用重要说明
使用本应用，即代表您同意按照本政策约定处理您的信息。
本应用无需注册账号，不收集姓名、手机号、邮箱、身份证等个人身份信息，不收集位置信息。
App 仅在设备本地读取设备型号、iOS 系统版本，用于界面适配、异常判断；仅本地读取，不会向外传输。
当前离线版本不使用 Cookie、不集成追踪 SDK、不读取广告标识符 IDFA，不存在跨应用追踪行为。
备注：如果未来版本新增广告功能，我们将完整更新本隐私政策，说明广告 SDK 的数据采集行为。
补充：若您通过邮件向我们发送反馈，是由您设备自带邮件程序完成发送，不属于本 App 主动上传数据。
重要：当前离线版本，App 不会把任何本地数据发送到外部服务器。
当前版本不会向任何第三方共享、出售、转让您的任何数据，没有接入第三方云服务、分析 SDK、支付 SDK。
如果后续版本新增广告 SDK，我们会更新本政策，列明第三方服务商及其数据处理规则。
当前版本无广告，不执行任何用户追踪。未来如上线广告功能，我们严格遵循苹果 ATT 框架，获取您明确授权后才执行追踪，您也可以在 iOS 系统设置关闭应用追踪权限。
仅在法律法规强制要求、有权机关出具合法有效法律文书的情况下，我们才依法进行信息披露（本 App 本身不持有您的线上数据）。
若发生合并、收购等业务变动，因为本版本用户数据全部保存在用户本机，不会发生用户数据流转；仅您主动发送给我们的邮件反馈信息，才可能随业务转移，并配套安全保护。
提醒：不存在绝对安全的电子系统，请妥善保管您的手机设备。
本应用面向电工、电气行业从业人员，并非专门面向 13 周岁以下未成年人。我们不会刻意收集未成年人个人信息。如果您发现未成年人向我们提交个人信息，请邮件联系我们，我们将立刻删除相关内容。
当前离线版本：App 不会上传任何用户数据，不存在 App 自动造成的数据跨境传输。
仅当您主动发送邮件反馈问题，由您自己设备邮件客户端发出信息，才有可能产生跨境传输。
我们可对本隐私政策进行更新调整。
普通调整会更新文档「最后更新日期」；重大变更（例如新增广告功能），会随 App 新版本发布公示告知用户。请您定期查阅本隐私政策。
如您对本隐私政策、数据处理有疑问，请联系：
本电工计算器仅作为电气行业辅助计算工具，所有计算逻辑均依据公开通用电工公式开发。
受限于参数输入错误、特殊工况边界条件、标准版本差异、软件潜在 Bug 等各类因素，本应用无法保证全部计算结果绝对准确无误。
电气作业属于高危工作，请勿将本 App 输出结果直接作为电气施工、设备选型、工程验收的唯一依据。所有现场实操、工程设计、安装施工，请务必由持证专业电工，结合现行国家电气规范、现场实际工况进行复核与校验。
在法律允许的最大范围内，对于因直接依赖本应用计算结果所产生的任何直接或间接损失、人身伤害，开发者不承担赔偿责任。

Company: Henan Yunfan Electronic Technology Co., Ltd.
This Privacy Policy describes how Henan Yunfan Electronic Technology Co., Ltd. ("we", "us", "our") processes information when you use our mobile application Electrician Calculator (the "App") available on Apple App Store.
Important Application Notice
By using this App, you agree to the data practices described in this Privacy Policy.
This App requires no account registration. We do NOT collect personal identifiable information including name, phone number, email, ID number or location data.
The App reads device model and iOS version locally only for UI adaptation and exception judgment. Such information stays on your device and will not be transmitted externally.
This offline version does not use cookies, tracking SDKs or IDFA. No cross‑app tracking activity is performed.
Note: If advertising features are added in future versions, we will fully update this policy to describe data collection of related advertising SDKs.
Supplement: When you send feedback via email, the message is sent by your device’s native mail client. It is not an active data upload triggered by the App itself.
Important: In current offline version, no local data will be sent to any external server.
We will not share, sell or transfer any of your data to any third‑party in current version. No third‑party cloud, analytics or payment SDK is integrated.
If advertising SDK is integrated in future releases, this policy will be updated to list third‑party service providers and their data processing rules.
There is no advertisement or user‑tracking behavior in current version. If we enable advertising in later versions, we will strictly comply with Apple ATT framework and obtain your explicit consent before tracking. You may disable App tracking permission in iOS system settings.
We may disclose information only when required by laws or valid legal documents issued by competent authorities. Please note that we hold none of your online user data for this offline App.
In case of merger or acquisition, user data remains on your local device and will not be transferred. Only feedback emails you voluntarily sent to us may be transferred with adequate data protection measures.
Reminder: No electronic system can guarantee absolute security. Please keep your mobile device properly secured.
This App targets electricians and electrical industry practitioners. It is not designed for children under 13 years old. We do not intentionally collect personal information from minors. If you find personal data submitted by a minor, please contact us via email and we will delete such information promptly.
For current offline version: The App does not upload user data automatically, so there is no automatic cross‑border data transfer caused by the App.
Cross‑border transmission may only occur when you voluntarily send feedback emails through your device’s native mail application.
We may revise this Privacy Policy. Minor adjustments will update the "Last Updated" date. Material changes (such as adding advertisement functions) will be announced together with new App release. Please review this policy periodically.
If you have any questions regarding this Privacy Policy or our data processing practices:
Electrician Calculator serves only as an auxiliary calculation tool for electrical industry. All calculation formulas are built based on public general‑purpose electrical engineering formulas.
Due to possible user input errors, special working‑condition edge cases, differences in industry standards and potential software bugs, we cannot guarantee 100% accuracy of all calculation outputs.
Electrical work involves high safety risks. Do NOT take calculation results from this App as the sole basis for electrical construction, equipment selection or project acceptance. All on‑site operation, engineering design and installation work must be reviewed and verified by licensed professional electricians complying with current national electrical codes and real‑site conditions.
To the fullest extent permitted by applicable law, the developer shall not be liable for any direct or indirect loss or personal injury caused by sole reliance on calculation results generated by this application.
