Is Definitions.net safe?

Clean risk

Definitions.net sends selected or focused-field text from the active page to the STANDS4 definitions API.

When you open the popup, Definitions.net checks the current page for selected text or text in the focused editable field, including on web pages and file URLs. It sends that text to www.abbreviations.com services to get count and definition results.
