01引言Introduction

龙截图 LongShot(以下简称「我们」或「本 App」)是一款面向 iPhone 的长截图拼接工具:把一段录屏、一叠截图或一整页网页拼成一张长图。本 App 的全部处理均在你设备上完成,不依赖任何服务器。本隐私政策旨在以清晰、坦诚的方式说明我们如何处理(以及更重要的——不处理)你的信息。 LongShot (“we”, “us” or “the App”) is a long-screenshot stitching tool for iPhone: it turns a screen recording, a stack of screenshots, or a full web page into one long image. All processing happens on your device, with no servers involved. This Privacy Policy explains, clearly and honestly, how we handle — and more importantly, do not handle — your information.

02我们收集的信息Information We Collect

我们不收集任何个人数据。具体而言,我们不收集: We collect no personal data. Specifically, we do not collect:

• 个人身份信息 —— 姓名、邮箱、电话号码等,因为我们没有账号与注册系统。 Personally identifiable information — name, email, phone number, etc., because we have no account or registration system.
• 使用与遥测数据 —— 我们不记录操作日志、崩溃堆栈、设备标识符或使用统计。 Usage and telemetry data — we do not log actions, crash stacks, device identifiers or usage statistics.
• 屏幕内容 —— 你录制的屏幕、选择的截图、拼接的长图与导出结果,均只在本地处理,我们无法访问。 Screen content — recordings you make, screenshots you pick, stitched results and exports are processed locally and are inaccessible to us.
• 定位、通讯录、日历等敏感信息 —— 本 App 不请求此类权限,也不具备相关功能。 Sensitive data such as location, contacts or calendars — the App neither requests nor has any such capability.

你通过 App Store 下载本 App 时,Apple 可能会依据其自身的隐私政策处理你的交易信息(如 Apple ID 与下载记录),这与本 App 无关,请参阅 Apple 的隐私政策。 When you download the App from the App Store, Apple may process your transaction data (such as Apple ID and download history) under its own Privacy Policy; this is outside our control. Please refer to Apple’s Privacy Policy.

03屏幕录制与图片处理Screen Recording and Image Processing

「录屏转长图」通过 iOS 系统的屏幕广播(Broadcast Upload Extension)实现:由你在系统界面中主动发起录制,录制内容以视频帧的形式直接写入本 App 在你设备上的共享容器,随后在你的设备上完成抽帧、对齐与拼接。 “Record to long screenshot” uses the iOS system Broadcast Upload Extension: recording is initiated by you in the system UI, and the captured frames are written directly into the App’s shared container on your device, where frame extraction, alignment and stitching are performed entirely on-device.

• 不经网络传输 —— 录屏帧不经过任何网络,不上传到任何服务器。 Never transmitted — recorded frames never travel over the network and are never uploaded to any server.
• 多图拼接 —— 你主动选择的照片仅在本机读取与计算,自动排序与对齐均为本地算法。 Multi-image stitching — photos you pick are read and computed locally; auto-ordering and alignment are local algorithms.
• 可随时中断 —— 录制由你在系统控制中心或 App 内随时停止,停止后可随时删除产生的数据。 Stops when you stop — you control recording from Control Center or the App, and can delete the data it produced at any time.

04网页快照(Safari 扩展)Web Snapshot (Safari Extension)

「网页快照」通过 Safari Web Extension 实现:只有当你在 Safari 中主动点击本扩展时,扩展才会读取当前网页的内容(HTML),并通过 iOS 的本地通信通道直接交给同一设备上的本 App,由 App 在本地渲染成一张长图。 “Web Snapshot” works through the Safari Web Extension: only when you actively invoke the extension in Safari does it read the current page’s HTML and hand it — via iOS local messaging — to the App on the same device, where it is rendered into one long image locally.

• 仅在你触发时读取 —— 扩展不会在后台读取或监控你的浏览记录,平时完全不工作。 Reads only on your action — the extension never reads or monitors your browsing in the background; it is idle otherwise.
• 不出设备 —— 网页内容只在你设备上的 App 与扩展之间传递,不发送到任何服务器。 Stays on device — page content only passes between the extension and the App on your device; nothing is sent to any server.
• 不用于浏览分析 —— 网页内容仅用于当场渲染长图,不做任何画像、分析或留存上报。 No browsing analytics — page content is used solely to render the image on the spot; no profiling, analytics or reporting.

05权限说明Permissions

本 App 仅在功能需要时请求权限,且全部遵循 iOS 的隐私保护机制,你可以在「设置 → 隐私与安全性」中随时查看和调整: The App requests permissions only when a feature needs them, always through iOS privacy protections. You can review and adjust them anytime in Settings → Privacy & Security:

• 相册写入(仅添加) —— 仅用于把你拼接好的长图保存到相册或整理进专属相册。不授权时仍可手动保存或分享,只是不能用自动保存。 Photo library (add-only) — used solely to save stitched images to your photo library or a dedicated album. Without it, you can still save and share manually; only auto-save is unavailable.
• 照片选择 —— 「多图拼接」使用系统照片选择器,你在其中选择的图片才会交给 App,选择过程本身不需要相册读取权限。 Photo picking — “Multi-image stitch” uses the system photo picker; only images you select are handed to the App, and picking requires no library access permission.
• 屏幕录制 —— 由你在系统界面主动发起(见第 03 条),录制范围是整个屏幕,内容只进入本 App 的本地处理流程。 Screen recording — initiated by you in the system UI (see Section 03); it captures the whole screen, and the content goes only into the App’s local processing pipeline.
• Safari 扩展 —— 需要你在 Safari 设置中手动开启;开启后也只有你主动点击扩展图标时才会读取当前网页(见第 04 条)。 Safari extension — must be enabled manually in Safari settings; even then, the current page is read only when you invoke the extension (see Section 04).

任何权限均不会被用于数据收集或追踪目的。 No permission is ever used for data collection or tracking purposes.

06数据存储与安全Storage and Security

• 无云端存储 —— 我们不建立、也不使用任何云服务器存储你的数据。 No cloud storage — we neither operate nor use any cloud servers to store your data.
• 本地历史 —— 「最近的长截图」列表与偏好设置仅保存在本机,不会同步到任何账户或云端。 Local history — the recent long-screenshot list and your preferences are stored on your device only, never synced to any account or cloud.
• 临时文件即用即清 —— 录屏帧与网页渲染的中间文件存放在 App 专属的本地容器中,处理完成后即可清理;你也可在 App 内一键清理历史。 Temp files, cleaned up — recorded frames and web-render intermediates live in the App’s own local container and can be cleaned after processing; you can also clear all history in the App with one tap.
• 卸载即清除 —— 删除本 App 后,其写入的全部本地数据(历史、缓存、临时文件)随之删除。 Uninstall wipes everything — when you delete the App, all local data it wrote (history, caches, temp files) is removed with it.
• 数据最小化 —— 由于我们不收集数据,也就没有可被泄露、丢失或滥用的数据面。 Data minimization — because we collect nothing, there is no data surface to leak, lose or abuse.

07与第三方共享Sharing with Third Parties

我们不会出售、出租、交易或以任何形式向第三方披露你的信息。本 App 不包含任何第三方广告、分析或追踪框架。 We do not sell, rent, trade or disclose your information to any third party in any form. The App contains no third-party advertising, analytics or tracking frameworks.

唯一例外是法律要求:若法律法规、司法程序或政府主管机关依法要求,我们将在法律允许的范围内配合。鉴于我们不持有任何用户数据,此类情况在事实上难以发生。 The sole exception is legal compliance: if laws, judicial proceedings or government authorities require it, we will comply to the extent permitted by law. In practice this is virtually impossible since we hold no user data.

08儿童隐私Children’s Privacy

本 App 面向一般用户,不针对儿童设计,也不面向儿童提供定向内容或功能。由于我们不收集任何个人信息,包括儿童在内的所有用户均不存在个人信息被收集的可能。若你发现我们意外收集了任何此类信息,请联系我们,我们将立即核实并处理。 The App is intended for general audiences and is not directed at children, nor does it offer targeted content or features for children. Since we collect no personal information, no personal data of any user — including children — can be collected. If you believe we have inadvertently collected such information, please contact us and we will investigate and resolve it promptly.

09你的权利与控制Your Rights and Control

• 完全掌控 —— 你的录屏、截图与拼接结果始终由你掌控:是否保存、是否导出、是否删除,均由你决定。 Full control — your recordings, screenshots and stitched results remain entirely yours: saving, exporting and deleting are always your call.
• 无需账户,即无删除流程 —— 我们没有账号系统,因此不存在需要「注销账户」或「申请删除数据」的流程;在 App 内删除历史、或直接卸载,即完成数据删除。 No account, nothing to delete — there is no account system, so there is no account-deletion or data-removal request to file; deleting history in the App, or uninstalling, completes data deletion.
• 撤回权限 —— 你可以随时在 iOS 设置中关闭相册写入、屏幕录制或 Safari 扩展,相关功能将受限,但不影响你继续使用其余功能或删除本 App。 Revoke permissions — you can turn off photo-library access, screen recording or the Safari extension in iOS Settings at any time; related features will be limited, and you can always delete the App.
• 查询与咨询 —— 如对本政策或数据处理有任何疑问,可随时通过下文联系方式与我们沟通。 Inquiries — if you have any questions about this policy or data handling, feel free to reach out via the contact details below.
