隐私政策 Privacy Policy

Scope

This Privacy Policy applies to the LaughShot iOS app ("the App"). By using the App, you agree to this policy.

适用范围

本隐私政策适用于 LaughShot iOS 应用（下称"本应用"）。使用本应用即表示您同意本隐私政策。

Information We Collect

• No accounts, contact details, or identity data are collected.
• No device identifiers, ad identifiers, or location data are collected.
• No third-party analytics or advertising SDKs are used.
• When you choose a video for analysis, the App temporarily processes face-related data from video frames on device, including whether a face is present, face count, face bounding box position, and expression-related numeric signals derived from facial landmarks, such as mouth openness, smile level, eye openness, brow raise, facial asymmetry, and head tilt.
• The App does not collect face templates, facial geometry profiles, or any biometric database used to identify a specific person, and it does not attempt to determine who the person is.

我们收集的信息

• 不收集账号、联系方式或身份信息。
• 不收集设备标识、广告标识或位置数据。
• 不使用第三方分析或广告 SDK。
• 当您选择视频进行分析时，应用会在设备本地临时处理视频帧中的面部相关数据，包括：人脸是否存在、人脸数量、人脸边界框位置，以及从面部关键点推导出的表情相关数值信号，例如嘴部张开度、微笑程度、眼睛开合、眉毛抬起、面部不对称和头部倾斜等。
• 本应用不会采集用于识别特定个人身份的人脸模板、面部几何档案或面部比对库，也不会尝试识别用户是谁。

How We Use Information

All processing happens locally on your device to:

• Select videos from your Photos library for analysis.
• Detect faces in video frames and estimate whether a face is centered and prominent in order to choose better moments for a Live Photo cover.
• Estimate expression intensity or emotion tendency from facial landmarks on device, such as laughter, surprise, goofy expression, or crying, solely to rank and filter candidate highlights.
• Generate and save Live Photos to your Photos library.

信息使用方式

所有处理均在您的设备本地完成，用于：

• 从照片库中选择视频进行分析。
• 检测视频帧中的人脸，并判断人脸是否位于画面中央、是否清晰可见，以帮助挑选更适合作为 Live Photo 封面的瞬间。
• 根据面部关键点在设备本地估计表情强度或情绪倾向，例如大笑、惊喜、搞怪表情或哭泣，仅用于候选高光的排序和筛选。
• 生成并保存 Live Photo 到您的照片库。

Sharing

共享

Storage & Security

Processed and generated content stays on your device or in your Photos library. The App does not upload or store content in the cloud. Face detection results, facial landmarks, and expression analysis results exist only temporarily in on-device memory during analysis for the current ranking session; after analysis finishes, the app is closed, or the task is cancelled, the App does not separately retain that face data. Only the Live Photo output that you choose to save is written to your Photos library.

存储与安全

处理与生成的内容保存在您的设备或照片库中，应用不上传或云端存储任何内容。人脸检测结果、面部关键点和表情分析结果仅在分析过程中于设备内存中短暂存在，用于生成当前次排序结果；分析结束、应用关闭或任务取消后，这些面部数据不会被我们单独保留。只有您主动保存的 Live Photo 成品会写入您的照片库。

Face Data

• Types of face data: face presence and count, face bounding box position, facial landmark availability, and expression or pose signals computed from landmarks.
• Purpose of use: to help the App find better moments in a video for Live Photo generation and rank them by expression intensity, subject prominence, and visual quality.
• Sharing: not shared with any third party and not used for advertising, profiling, tracking, or identity recognition.
• Storage location: processed locally on the user's device only; not uploaded to servers and not stored in developer-controlled cloud services.
• Retention period: retained only temporarily in device memory during a single analysis session and not kept by the App after analysis completes, the App is closed, or the task is cancelled.

面部数据

• 面部数据类型：人脸是否存在、人脸数量、人脸边界框位置、面部关键点可用性，以及由关键点计算出的表情或姿态信号。
• 使用目的：帮助应用找出更适合作为 Live Photo 的视频瞬间，并按照表情强度、主体突出程度和画面效果进行排序。
• 共享情况：不会与任何第三方共享，也不会用于广告、画像、追踪或身份识别。
• 存储位置：仅在用户设备本地处理，不上传到服务器，也不存储在开发者控制的云服务中。
• 保留时间：仅在一次分析会话的设备内存中临时存在；分析完成、应用关闭或任务取消后不会继续保留。

Your Rights

You can revoke Photos access at any time in iOS Settings or delete generated content.

您的权利

您可以随时在 iOS 设置中撤销照片访问权限，也可以删除已生成的内容。
