Privacy Policy

Silhouette is a native macOS application for background removal. This policy describes what data the app handles, what leaves your Mac, and what does not. In short: your images never leave your Mac, and we do not run any server that receives your work.

Who this policy covers

This policy applies to the Silhouette macOS app and to this website at silhouette.mgcrea.io. It does not cover third-party websites or services you may reach by following links from the app or site.

Summary

• All image processing happens on your Mac, on the Neural Engine and GPU.
• No image, mask, or export ever leaves your device.
• No account, sign-in, or user profile is required or created.
• No analytics or telemetry is collected by Silhouette.
• The only network traffic originates from explicit actions you take — e.g. downloading an optional matting model, or checking for an app update.

What stays on your Mac

The following data is stored locally and never transmitted to us or any third party:

• Your images and exports. Source photos, cached mattes, and exported cutouts remain on disk where you placed them.
• Your collections and edits. Collection metadata, tune settings, and per-image state are kept in the app's local support directory under ~/Library/Containers/io.mgcrea.Silhouette/.
• Your preferences. Window state, theme, and other UI settings are stored in the app's standard user defaults.
• Model files. Matting models you download are cached on disk and re-used across sessions.

What we do not collect

• No analytics, usage metrics, or behavioural telemetry.
• No crash reports are sent to Silhouette. If you have enabled macOS's built-in Share Mac Analytics system-wide, Apple may collect diagnostics per your Apple privacy settings — that data is handled by Apple, not by us.
• No advertising identifiers.
• No account, email, or personal information.

Network access

Silhouette does make network requests, but only in response to actions you take:

• Optional model downloads. When you choose to download a matting model that is not already on your Mac, Silhouette fetches it from its hosted source (for example, a model repository on Hugging Face or GitHub). The request contains only what is required to retrieve the file and is not sent to Silhouette.
• Update checks. The app may check for a new version by contacting an update feed we operate. The request is anonymous and contains only your current app version and the platform (macOS).

Silhouette will never upload your images, masks, exports, or collection contents.

Third-party services

Silhouette does not integrate third-party analytics, advertising, or tracking SDKs. Model files may be hosted by third parties (for example, model repositories); those hosts will see the standard request metadata required to serve a file (IP address, user agent) per their own privacy policies.

Children's privacy

Silhouette is a general-audience creative tool and is not directed at children under 13. We do not knowingly collect personal information from children.

Your rights

Because Silhouette does not collect personal information, there is nothing for us to access, correct, or delete on your behalf. All app data lives in your user library and you can remove it at any time by deleting the app or its container directory.

Changes to this policy

We will update this page if the app's data handling changes in a material way. The "Last updated" date above reflects the most recent revision.
