How to how to check a tool does not upload

  1. 1. Open the network panel before you drop a file.
  2. 2. Run the tool and look for a request to any other origin.
  3. 3. Disconnect and run it again. It should finish.

Open the browser’s network panel, filter it, and note the origins before you add a file. Add a PDF and run the tool. New requests should stay on the same site, and they should be the app’s own files if any are still loading, not a POST of the document to an API. Then repeat with the network disabled after the ready state. A tool that passes both checks is not uploading. A tool that shows a progress label “uploading” has told you the truth. Ignore badges. A privacy policy is not a network log. This site expects to pass that test; if you ever see a document POST, treat it as a bug and stop using that build.
