Privacy Policy

• File access (the only one). When you tap import, iOS shows its own file picker and you choose which files or folders the app may read. The app receives access only to what you actively selected, and it copies those files into its own sandbox. It does not scan your device, browse your folders in the background, or read files you did not pick.
• No network permission. The app cannot reach the internet, so uploading is not possible even in principle.
• No Photo Library access. The app never reads your photos. When you export a PNG, the iOS share sheet is presented and you decide where that single file goes.
• No camera, no microphone, no location, no contacts, no HealthKit, no Sign in with Apple. None of these are requested, so none can be used.

文件读取（唯一的权限用途）。点击导入后由 iOS 弹出系统文件选择器，你亲自选择允许 App 读取的文件或文件夹。 App 只获得你主动选择的那部分内容，并把它们复制进自己的沙盒；它不会扫描你的设备、不会在后台浏览你的目录、也不会读取你没选的文件。
没有联网权限。App 无法访问网络，因此从原理上就不可能上传。
不读取相册。App 从不读取你的照片。导出 PNG 时打开的是系统分享面板，这个文件去哪里由你决定。
不使用相机、麦克风、定位、通讯录、健康数据、通过 Apple 登录。这些权限一个都没有申请，因此也不可能被使用。

• No name, email address, phone number, contacts or address book.
• No patient data: no patient names, IDs, birth dates, study descriptions, pixel data, file names or file lists.
• No analytics, no crash reporting, no advertising identifiers, no attribution or fingerprinting.
• No third-party SDKs of any kind — nothing of ours runs your data through somebody else’s code.
• No account, no sign-in, no subscription, no purchase flow.
• No IP address or device log kept by us, because there is no service of ours that could receive it.

✕ 不收集姓名、邮箱、电话号码、通讯录或联系人。
✕ 不收集患者数据：患者姓名、编号、出生日期、检查描述、像素数据、文件名与文件清单都不收集。
✕ 不做统计分析、不接崩溃上报、不采集广告标识符、不做归因或设备指纹。
✕ 不集成任何第三方 SDK——你的数据不会经过任何别人的代码。
✕ 没有账号、不需要登录、没有订阅、没有内购。
✕ 我们不记录 IP 地址或设备日志，因为我们根本没有可以接收它们的服务。

Imported files are copied into the app’s sandbox, which is storage iOS reserves for this app on your device. The library screen shows how many files are stored there. No copy is made on any server, and no copy is sent to the developer. The files you imported into the Files app stay where you put them; the app only keeps its own copies.

导入的文件被复制进 App 的沙盒——那是 iOS 在你设备上划给本 App 的专属存储。图库界面会显示当前存放的文件数量。 任何服务器上都不存在副本，也不会有任何副本发给开发者。你放在「文件」App 里的原件留在原地，App 只保留自己那份副本。

• One series. Delete a series from the library and its files are removed from the sandbox.
• Everything. Use Delete all images (清空全部影像) in the library to remove every imported file in one action.
• All of it, including settings. Delete the app from your device. iOS removes the app’s sandbox together with it, so nothing of yours remains.
• Exported PNGs. Those live wherever you sent them (for example your Photo Library); delete them there. The app keeps no copy of what you exported.
• No request needed. Because nothing is held by us, there is no data-subject deletion or export request for you to file and for us to answer.

单个序列。在图库里删除某个序列，它的文件就从沙盒中移除。
全部影像。用图库里的「清空全部影像」一次移除所有导入文件。
连同设置一起清空。直接卸载 App，iOS 会连同沙盒一并删除，你的数据不会残留。
已导出的 PNG。它们存在于你发送到的位置（例如照片 App），请到那里删除；App 不保留导出副本。
无需提交请求。由于我们手里没有任何数据，你不必提出删除或导数据的请求，我们也无需处理。

There is no advertising in the app, no tracking across apps or websites, and no third-party code inside it. Nothing about your usage — which files you opened, which window settings you use, how long you stayed — is recorded or reported anywhere. The App Store “Data Used to Track You” and “Data Linked to You” sections for this app should therefore be empty; if you ever find them populated, that would be a bug worth reporting.

App 内没有广告，没有跨 App 与跨网站的追踪行为，内部也没有任何第三方代码。你的使用情况——打开了哪些文件、用了什么窗口参数、 停留多久——都不会被记录或上报。因此本 App 在 App Store 上的「用于追踪你的数据」与「与你关联的数据」应当都是空的；如果你看到被填上了内容，那是一个值得报告的错误。

The app collects no data from anyone, so it collects no data from children either — there is nothing to delete, by design. The app is not directed at children and asks for no personal information. If a child’s DICOM study is opened on a device, that file stays inside the app’s sandbox on that device like any other file, and the parent or guardian can remove it with the controls described above.

本 App 不向任何人收集数据，因此也不收集儿童的数据——按设计就没有可删除的东西。App 不以儿童为对象，也不要求提供任何个人信息。 如果设备里打开了儿童的 DICOM 检查文件，它和其他文件一样只留在该设备的 App 沙盒内，家长或监护人可用上文的方式删除。

This privacy and support site serves static HTML files only. It sets no cookies, uses no local storage, loads no third-party scripts, fonts or images, and runs no analytics. The pages themselves are written to work with zero external requests, which is the same rule the app follows. Your host’s web server may still write ordinary access logs; that is the hosting provider, not the app, and we do not add any tracking of our own.

本隐私与支持站点只提供静态 HTML 文件：不设 Cookie、不使用本地存储、不加载任何第三方脚本/字体/图片、不做统计分析。 页面本身按「零外部请求」编写，这也正是本 App 遵循的同一条规则。你的托管服务器仍可能记录普通的访问日志，那属于托管服务商而不是 App，我们自身不添加任何追踪。

Under GDPR, CCPA/CPRA and similar frameworks you may request access, correction, deletion, portability or a restriction on processing. With this app those rights are satisfied by its design: we hold nothing about you, so there is nothing for us to disclose, correct, export or delete. If you would like written confirmation of that, or you believe this page is inaccurate, email liangsx.168@gmail.com — you will get a reply from a human: the developer.

在 GDPR、CCPA/CPRA 等法规下，你可以请求访问、更正、删除、可携带或限制处理。对本 App 而言，这些权利由设计本身满足： 我们不持有你的任何信息，因此没有可披露、可更正、可导出、可删除的内容。如果你希望获得书面确认，或认为本页描述不准确， 请发邮件到 liangsx.168@gmail.com——回复你的是人，也就是开发者本人。

Any update is published at this address with a new effective date below. Material changes will also be reflected in the app’s “Read Before Use” screen.

任何更新都会发布在本地址，并在下方标注新的生效日期。实质性变更同时会反映在 App 的「使用前必读」页面中。
