Google has released a blog post outlining their approach to government requests for your information. Google says they have released this information due to it being Data Privacy Day, “when the world recognizes the importance of preserving your online privacy and security.”
Below is what Google said their in their blog post, where they outline what they do:
We scrutinize the request carefully to make sure it satisfies the law and our policies. For us to consider complying, it generally must be made in writing, signed by an authorized official of the requesting agency and issued under an appropriate law.
We evaluate the scope of the request. If it’s overly broad, we may refuse to provide the information or seek to narrow the request. We do this frequently.
We notify users about legal demands when appropriate so that they can contact the entity requesting it or consult a lawyer. Sometimes we can’t, either because we’re legally prohibited (in which case we sometimes seek to lift gag orders or unseal search warrants) or we don’t have their verified contact information.
We require that government agencies conducting criminal investigations use a search warrant to compel us to provide a user’s search query information and private content stored in a Google Account—such as Gmail messages, documents, photos and YouTube videos. We believe a warrant is required by the Fourth Amendment to the U.S. Constitution, which prohibits unreasonable search and seizure and overrides conflicting provisions in ECPA.
