I'm no expert, but I think removing the postal code is the obvious way to anonymize. If you can't restrict to a specific geographic area, then who knows who you are. Pragmatically speaking, I noticed that in their "test toggling variables" widget at the end, removing postal code instantly dropped my probability of detection to 0, no matter what other fields were active. So perhaps your geographic location is the information you should be most paranoid about sharing.
