Sync

If you use iCloud Photos to sync photos across multiple devices, keywords, captions, and ratings in the System Library already follow iCloud Photos. Use HashPhotos Sync for timeline events and smart albums.

The Local Library does not support sync.
On iOS 26 and earlier — Keywords, memos, and ratings are HashPhotos-only, so include them in this manual sync along with timeline events and smart albums.
