For non-coders, if you are concerned about us using your data (we won't!) you can a) trust us, b) ask someone to check for you, or c) go to the page, turn off your wifi (so you aren't connected to the internet), generate your archive and download, close the page, and then click back on wifi... easy peasy :)
