What is ShareGuard: Auto Mosaic?
ShareGuard: Auto Mosaic is a photo privacy app for Mac that helps users prepare images for safer sharing. It focuses on protecting sensitive details in screenshots and photos by masking faces and text, applying mosaic effects, and removing embedded metadata such as location, camera, and timestamp information. The app supports automatic detection as well as manual adjustment, which is useful when you need quick batch processing or more precise edits on a single image. It is designed for everyday sharing workflows, including posting online, sending screenshots, or distributing work images that contain personal or confidential details. ShareGuard: Auto Mosaic is also available across Apple platforms, so people who work between Mac, iPhone, and iPad can use a similar privacy-focused editing workflow.

Safety overview
Status: Mostly safe
This is a legitimate photo-editing and privacy utility distributed through the Apple App Store. Access to your photo library or selected images is consistent with its purpose, since it needs image access to detect faces, text, and metadata before export. As with any app that processes personal images, review the photos you import and confirm the export result before sharing, especially when relying on automatic masking.
Recommendation: Keep ShareGuard: Auto Mosaic if you use it to redact screenshots or photos before sharing. If you no longer need its privacy-editing tools, you can remove it like other Mac apps without affecting macOS itself.
