However, this year Google stated in an official policy:
>We notify users about legal demands when appropriate, unless prohibited by law or court order.

The nebulous language of “when appropriate” is not the firm commitment that should be the gold standard for transparency around handing data to the government. While we’re disappointed by Google’s decision to make its policy language so open-ended, we hope the strong commitments made by other major Internet companies will inspire Google to adopt a clearer public stance in the years to come.
