Privacy — BreeZ

The short version 一句话版本

BreeZ does not collect any personal data. We have no servers, no analytics, no advertising, no third‑party SDKs. Everything happens on your device. BreeZ 不收集任何个人数据。 没有服务器、没有分析、没有广告、没有第三方 SDK。一切都发生在你自己的设备上。

Data we collect 我们收集的数据

None. BreeZ has no account system and never sends data off your device. The simulation, image processing and rendering are all local computations. 没有。BreeZ 没有账号系统，也不会把任何数据发送出你的设备。仿真、图像处理和渲染全部在本地完成。

Data stored on your device 在你设备上保存的数据

BreeZ saves your documents (the shapes you draw and their settings) locally so you can come back to them. These files live in the app's own sandbox; uninstalling the app removes them. Nothing is uploaded. BreeZ 会把你的文档（你画的形状和相关设置）保存在本地，方便下次继续。这些文件位于 app 的沙盒中，卸载即清除。不会上传任何内容。

Permissions we may ask for 可能用到的权限

Photo library — only if you choose to import a shape from a photo. The selected image is processed on‑device and never leaves it. 相册——仅当你选择"从图片导入形状"时使用。所选图片在本地处理，不会离开设备。
Camera — only if you choose to capture a new photo to import. 相机——仅当你选择"拍照导入"时使用。
Save to Photos — only when you save an exported still or video. 保存到相册——仅当你导出静态图或视频并保存时使用。

Third parties 第三方

There are none. BreeZ is built on Apple frameworks only (SwiftUI, Metal, Vision, PhotosUI, Accelerate, AVFoundation). No analytics, advertising, crash‑reporting or networking SDKs are linked into the app. 没有。BreeZ 仅使用 Apple 自家框架（SwiftUI、Metal、Vision、PhotosUI、Accelerate、AVFoundation）。未集成任何分析、广告、崩溃上报或网络相关 SDK。

Children 儿童

BreeZ is safe for children to use because it collects nothing. There is no signup, no chat, no third‑party content delivered through the app. BreeZ 适合儿童使用，因为它不收集任何信息。没有注册、没有聊天、没有通过 app 投放的第三方内容。

Changes to this policy 本政策的更新

If this policy ever needs to change — for example if a future version adds a feature that requires data — we'll update this page and bump the date at the top. 如果将来本政策需要更新——例如新版本加入了需要数据的功能—— 我们会修改本页内容，并更新顶部的日期。
