The direct answer
No. SnapAction’s core workflow is to scan selected screenshots and create resource cards. It does not need to delete the original screenshots from Photos.
The app uses PhotoKit to read screenshot assets you choose to scan. After cloud-assisted analysis, it stores resource records locally with SwiftData. Those records are separate from the original images in your Photos library.
What SnapAction saves
A resource card can include a title, URL when available, type, tags, metadata, favorite state, read state, scan records, and references back to screenshot asset IDs.
That gives you a structured layer over your screenshots without requiring SnapAction to become a photo cleaner or replacement for Photos.
If you are cleaning up screenshots
Use SnapAction first to preserve useful resources from high-value screenshots. Then decide separately whether you want to delete, archive, favorite, or keep the original images in Photos.
