Silo Sweep.
The photo cleaner that never sees your photos.
Run the whole cleanup in Airplane Mode.
Every fingerprint, digest and blur score is computed with Apple's own frameworks (Photos, Vision, Core Graphics, CryptoKit) inside the app's sandbox on your device. The cleanup makes no network requests on any device, and Silo Sweep never downloads an original from iCloud either, so turn the network off and the scan, review and delete flow still runs end to end. The one network feature is optional and Mac only: in Silo Sweep 1.7.1 for Mac, the Semantic image pilot downloads its vision model once, after you agree, and none of your photos are sent.
You decide. Apple confirms. Thirty days to change your mind.
Nothing leaves the review queue without your decision: swipe on iPhone and iPad, drag or use the arrow keys on the Mac. Each group always keeps at least one photo, and there is no auto-delete mode. A photo you toss from the Photos library then passes Apple's own confirmation and waits thirty days in Recently Deleted. On the Mac, a file you toss after a catalog scan goes to the Trash instead, and the catalog itself is never written.
The receipt is the whole relationship.
One $9.99 purchase covers iPhone, iPad and Mac. There is no account to make, no analytics and no subscription to cancel. What stays with you is the record of every sweep: what you asked to remove, and what the library confirmed was actually gone.
What it does.
A perceptual hash proposes candidates, and a Vision feature-print comparison can veto a pair that only looks alike. A photo joins a group only if it resembles that group's keeper directly, never through a chain of in-between shots. Two items are called exact duplicates only when a SHA-256 digest of their real image data matches, including a Live Photo's video and any edited version.
Laplacian-variance sharpness suggests the keeper in every group, and in a burst face presence is weighed too, but only when every frame could be checked. The scan also counts screenshots and clearly soft frames, and lists screen recordings and videos of 200 MB or more for review on their own. Nothing is ever auto-selected, and every suggestion is yours to override.
After a sweep, Silo Sweep reads the library back and reports what actually moved, what was already gone and what it could not check. Space stays pending until Recently Deleted clears, or until you empty the Trash after a catalog scan. A queued photo is never counted as deleted, and the record exports as a CSV file. With Limited Library access it says so instead of guessing.
Silo Sweep looks at photos: the Photos library on iPhone, iPad and Mac, and on the Mac a Lightroom Classic or Capture One catalog, which it reads without changing. You allow each folder the catalog keeps photos in, one panel at a time. Want to see a full review before granting any access? Open the built-in sample library. Looking for duplicate files in Downloads or other folders on your Mac? That is Silo Tidy.
