Is iCloud Bookmarks safe?

Clean risk

iCloud Bookmarks transmits your complete bookmark tree to the native iCloud Bookmarks app on your Mac via native messaging.

On startup, the extension reads your full bookmark tree using the bookmarks API and sends each folder and bookmark entry to the native host com.apple.bookmarks. It then continues to forward incremental changes — additions, removals, moves, and edits — as they occur, keeping the macOS iCloud Bookmarks app in sync.
