### 1. Album Management Features
1. Photo cleaning and classification: In the double-column browsing mode, you can batch delete photos by swiping left or right arbitrarily. Turning on the album sorting mode can accelerate photo sorting.
2. AI photo search with one sentence: It understands "human language" so you don't have to worry about what keywords to use for searching. It supports searching by text and image. You can search like this: "The setting sun and the lone wild duck fly together", "How to batch delete photos".
3. Free photo filtering: Light Flicker will automatically identify photo types (taken by mobile phone, rear camera, self-taken, etc.), and there are also filtering dimensions such as time, album, location, etc., making it easy to filter out the photos you want to view.
### 2. Regarding Permissions
1. Photo permissions: All photo permissions are required for normal display. Photos remain local and no photos will be uploaded.
2. Network permissions: Network permissions are required when viewing large images or using the semantic search function because large images may be stored in iCloud and need to be loaded via the network, and semantic search requires AI to identify question types.
3. Reminder: If your iOS system is lower than 16.0, some functions will not be available.
