Link types: noreferrer

The noreferrer keyword for the rel attribute of the <a>, <area>, and <form> elements instructs the browser, when navigating to the target resource, to omit the Referer header and otherwise leak no referrer information — and additionally to behave as if the noopener keyword were also specified.
