No, all parsing and drawing of diagrams is executed solely on the client side in your browser. (In the past, the share URL button used a query parameter to transport the diagram data, which meant that the data in the URL was visible in the http access logs when someone used the generated URL. In the current version, fragment '#' is used instead, which according to https://tools.ietf.org/html/rfc3986#section-3.5 is dereferenced solely by the user agent)
