Privacy Policy
Finger Filter ("the App") is a camera app that tracks your hand in real time and places a visual filter in the gaps between your fingers. This policy explains what happens to your data when you use it.
The short version
The App has no servers, no analytics, no advertising, and no user accounts. It does not send anything you do — no video frame, no photo, no setting — anywhere over the network. Everything described below happens only on your device.
Camera and microphone
The App uses your device's camera to detect your hand position and render the filter live on screen. If you choose to record, the App also captures audio through the microphone unless you turn the microphone off first. This processing happens entirely on your device, in real time. No video frame or audio sample is ever transmitted off the device.
Saved recordings
While you are recording, the App writes the video to a temporary file inside its own sandboxed storage. When you finish, you decide what happens to it: save it to your Photo Library, share it through the system share sheet, or discard it. The App does not keep a copy once it has been saved or discarded, and it never uploads it anywhere on your behalf.
Photo Library access
The App only requests permission to add new items to your Photo Library. It cannot browse, read, or modify anything already in your library.
Settings stored on your device
A small number of preferences — such as whether the microphone is on, which on-screen
overlays are visible, and which filter you last chose for each hand region — are saved
locally on your device using Apple's standard preferences storage (UserDefaults).
These preferences never leave your device and are deleted if you uninstall the App.
Third parties
The App does not include any third-party analytics, advertising, or tracking software development kits (SDKs). No data about you or your usage is shared with any third party, because none is collected in the first place.
Children's privacy
The App is not directed at children under 13, and does not knowingly collect any information from anyone, regardless of age — it simply does not collect information at all, as described above.
Changes to this policy
If this policy changes, the "Last updated" date at the top of this page will change with it. Continued use of the App after an update constitutes acceptance of the revised policy.

隐私政策
「手势滤镜」(以下称"本 App")是一款通过实时追踪手部位置、在手指间隙叠加视觉滤镜的相机应用。 本政策说明你在使用本 App 时,你的数据会经历什么。
先说结论
本 App 没有服务器、没有数据统计、没有广告,也不需要注册账号。你在 App 内的任何行为—— 不论是一帧画面、一张照片,还是一项设置——都不会通过网络发送到任何地方。以下描述的一切, 都只发生在你自己的设备上。
摄像头与麦克风
本 App 使用设备摄像头识别你的手部位置,并将滤镜实时渲染在画面上。如果你选择录制, 本 App 还会通过麦克风采集声音,除非你事先关闭了麦克风。这些处理完全在你的设备本地、 实时完成,任何视频画面或音频片段都不会被传出设备。
录制内容的保存
录制过程中,本 App 会把视频写入其自身的沙盒临时文件中。录制结束后,如何处理这段视频 由你决定:保存到相册、通过系统分享面板发送出去,或者直接丢弃。无论哪种情况,本 App 都不会保留一份副本,也绝不会代替你把它上传到任何地方。
相册权限
本 App 只请求"添加"权限,用于把新内容写入你的相册。它不能浏览、读取或修改你相册中 已有的任何内容。
保存在设备本地的设置
少量偏好设置——例如麦克风是否开启、屏幕上显示哪些辅助叠加层、你上次为每个手指区域
选择的滤镜——会通过 Apple 标准的偏好存储机制(UserDefaults)保存在你的设备本地。
这些设置永远不会离开你的设备,卸载 App 时会一并删除。
第三方
本 App 不包含任何第三方数据统计、广告或追踪 SDK。因为本 App 本身不收集任何数据, 所以也没有任何数据可以分享给第三方。
儿童隐私
本 App 并非面向 13 岁以下儿童设计,也不会有意收集任何人的信息——无论年龄大小, 原因很简单:如上所述,本 App 完全不收集信息。
政策变更
如果本政策发生变更,页面顶部的"最后更新"日期会随之更新。变更后继续使用本 App, 即表示你接受修订后的政策。
