Is Handy Screenshot safe?

Low risk

Handy Screenshot exposes its most recent screenshot data URL to pages through its content-script message bridge.

Handy Screenshot injects a content script on all websites and uses a page message bridge for its screenshot capture iframe. The bridge accepts page messages and can forward a request to the background script, which returns the extension's most recent screenshot data URL.
