The short version
Silo Sweep collects no data. None.
No analytics. No telemetry. No account. No personal data. No usage metrics. No error beacons. No advertising IDs. No fingerprinting. No crash reports. No data of any kind is collected, stored, transmitted, or shared by Silo Sweep about you, your device, or your content.
Everything Silo Sweep does runs entirely on your device — Mac, iPad, or iPhone — using Apple's own on-device frameworks (Vision, Accelerate, PhotoKit). v1.0 ships with no network entitlement at all: turn off the network and it still works, end to end. There is no cloud component. There is no server. There is no Silo Sweep account.
What we don't have, and therefore never see
Because Silo Sweep has no server-side component, none of the following exists anywhere in our infrastructure (which consists of: nothing): your name, email, phone, or address; your IP address, device identifier, or any hardware fingerprint; your content and anything derived from it; session timing, feature usage, or behavioural data; crash reports. The app does not phone home, ever.
Outbound traffic you initiate
The only outbound network traffic, all user-initiated, and none of it to Silo Sweep:
- App Store updates.When Apple ships a Silo Sweep update, the App Store delivers it. This traffic is between your Mac and Apple's servers. Silo Sweep is not involved.
- Links you click. If you click an external link inside the app, your default browser handles the request. Silo Sweep is not involved.
Permissions we request, and why
- Your photo library. Read your photos to find duplicates, near-duplicates, bursts, blurry shots and screenshots, and to move the items you confirm into Recently Deleted. Requested only when you tap Scan, never at launch. Limited Library mode is fully supported.
Silo Sweep does not request Camera, Contacts, Location, or Full Disk Access beyond what is listed above. If you grant nothing, it can read nothing.
On-device data you create
Your content and everything derived from it live on your disk under ~/Library/Containers/com.silosystems.silosweep/Data/Library/Application Support/SiloSweep/ (plus any folder you explicitly choose to export to). They are yours. We do not have access to them. Deleting Silo Sweep removes the app; your work remains under its container until you delete it manually.
Third-party components
Silo Sweep uses these Apple system frameworks, all running entirely on-device. None of them receive any data about you from Silo Sweep, and none require a network connection:
- Vision (feature print) — runs locally on-device.
- Vision (image classification) — runs locally on-device.
- Accelerate / vDSP — runs locally on-device.
Children's privacy
Silo Sweep is rated 4+. Because no personal data is collected from any user, no special treatment is required for users under 13. Same policy applies regardless of age: nothing collected.
Changes
If we ever materially change how Silo Sweep handles data, we will publish an updated version of this page, announce the change prominently in the release notes, and require explicit consent in-app before any new collection begins. The current policy is: nothing is collected.
