Google Docs and other third-party services are mighty convenient. They make it easy to share information and store big files on someone else's server (freeing up space on our own computers). But EFF's Bankston cautions against it when possible.
Very little is known about surveillance compliance, or how amenable companies are to handing over our information to the government, he said. But the small window we do have into this "shadowy" world, he said, indicates that we can't count on third party companies with which we store information to stand up for us.
"We have to assume the worst -- that when companies are approached for information, they aren't going to put up a fight," he said.
At some point it will ideally be safer to do more "in the cloud," but until those services are more secure, privacy experts recommend storing important files on your own computer.
