2.2 本地数据存储

2.2 Local Data Storage

本应用仅在您的设备本地存储以下信息：

This app only stores the following information locally on your device:

• 照片评分数据：当您为照片设置评分（0-5星）时，评分信息会同时以XMP（可扩展元数据平台）和EXIF两种标准格式写入到照片文件的元数据中。XMP格式用于专业照片管理软件的兼容性，EXIF格式提供更广泛的兼容性支持。此数据完全保存在您的本地设备上，不会离开您的设备。
• Photo Rating Data: When you set a rating (0-5 stars) for a photo, the rating information is written to the photo file's metadata in both XMP (Extensible Metadata Platform) and EXIF standard formats. XMP format is used for compatibility with professional photo management software, while EXIF format provides broader compatibility. This data is completely stored on your local device and never leaves your device.
• 用户偏好设置：包括排序方式、窗口大小等界面偏好设置，这些设置仅存储在您的Mac系统UserDefaults中，不会与任何第三方共享。
• User Preferences: Including sorting methods, window sizes, and other interface preferences. These settings are only stored in your Mac's UserDefaults and are not shared with any third parties.
