Is workbench officially run / supported by Salesforce?

If I am executing queries and downloading data using the bulk api, is that data stored on the workbench hosted platform before being downloaded or is it simply parsing the file to the local machine directly from Salesforce without being stored in the middle.
Similarly if I am uploading files for ad-hoc bulk processing, is this data stored on the workbench hosted platform before being submitted to Salesforce for processing.
