CodePen 2.0 Sends Data to Servers Immediately While Typing

CodePen 2.0 transmits data entered into its editor to its servers almost immediately, according to user testing. A user reported that after typing a unique marker into the index.html file, the data appeared in the Network/Response tab within 1-2 seconds, even before the file was saved. The user confirmed that the marker was visible in the HTML served from the generated preview on codepen.dev, despite the build being run with the 'save:false' option. This raises concerns about the security of any sensitive information entered into the editor, as it may be compromised even if the user does not publish or save their work.
