Is Grepper safe?

Clean risk

Grepper sends Google searches, result URLs, and saved code snippets to www.grepper.com.

On Google search pages, Grepper reads the search term and visible result URLs so it can fetch and display answer overlays from its service. On other pages, it can add controls to code blocks or use a keyboard shortcut to save selected code snippets, including source URL and language context, to Grepper.
