The Scholarcy Chrome extension has passed all of Google’s automated and manual security checks and is safe to use. The extension only needs to read the current URL of the page you have open and its content type. You can also give it permission to upload PDF files from your computer. It does not read or change any data on the page. You will also see the same warning on practically all Chrome Extensions including chart-topping extensions such as Grammarly and Evernote.
