Is Calibre Search safe?

Clean risk

Calibre Search sends selected page text to a local Calibre native messaging host when you start a search.

When you use the context menu, toolbar button, or keyboard shortcut, Calibre Search reads the current selection, selected input text, or link text from HTTP(S) pages. It builds a calibre:// search URL from that text and sends it to the local native messaging host configured for Calibre search.
