Privacy Policy

Window Flow doesn’t collect any personal data.

Your windows stay on your Mac

To show your windows, Window Flow needs macOS’s Accessibility and Screen Recording permissions. It uses them only to list your open windows, read their titles, and draw previews of them while the flow is on screen. All of this happens on your Mac: previews are kept in memory, never saved to disk, and never sent anywhere.

No accounts, analytics or ads

There’s no sign-in, no analytics or tracking, no advertising, and no third-party code that collects data.

Updates

Window Flow asks before it checks for updates on its own. When it checks, it downloads a small update feed from boyucheng.me, at most about once a day. Like any web request, this shows the server, which Cloudflare hosts, your IP address and the app’s version. Nothing else is sent.

Settings

Your choices, such as the flow, the background and the window size, are saved on your Mac.

This website

This site sets no cookies. Cloudflare, which hosts it, counts visits with its Web Analytics, which uses no cookies and doesn’t identify you. The site remembers the language you choose in your browser.

Changes

If this ever changes, this policy will be updated before the app does anything different.

隐私政策

Window Flow 不收集任何个人数据。

你的窗口只留在你的 Mac 上

为了显示你的窗口，Window Flow 需要 macOS 的“辅助功能”和“屏幕录制”权限。它只用这些权限列出你打开的窗口、读取窗口标题，并在切换界面显示时绘制窗口预览。这些都在你的 Mac 上完成：预览只保存在内存中，不会写入磁盘，也不会发送到任何地方。

没有账户、统计或广告

不需要登录，没有统计或追踪，没有广告，也没有任何收集数据的第三方代码。

更新

Window Flow 会先征得你的同意，再自动检查更新。检查时，它会从 boyucheng.me 下载一个很小的更新信息文件，大约每天最多一次。和任何网络请求一样，服务器（由 Cloudflare 托管）会看到你的 IP 地址和 App 的版本号。除此之外，不会发送任何信息。

设置

你的偏好设置，例如排列方式、背景和窗口大小，都保存在你的 Mac 上。
