Privacy, Security & Your Dropbox (The Dropbox Blog)
Like many of you, we’ve been reading the reports about a change we made to our Terms of Service, and more generally about Dropbox’s approach to privacy and security.
Everyone who works at Dropbox knows our most important asset is the trust of our users. Dropbox is used by millions of people every day, including our own friends and families, and we promise them — and all of you — that we work hard to keep your most important data safe, secure, and private.
In this post, we’d like to go through each of the concerns that has been raised, and provide you with answers that we hope you feel are complete, transparent, and straightforward. We also provide detail on specific technical concerns. We look forward to your feedback, and will continue to strive to make our policies as easy to understand as Dropbox is to use. Our goal is to have an open and honest relationship with you so that we can address all of these issues quickly and effectively.
Compliance with Laws and Law Enforcement Requests; Protection of Dropbox’s Rights. We may disclose to parties outside Dropbox files stored in your Dropbox and information about you that we collect when we have a good faith belief that disclosure is reasonably necessary to (a) comply with a law, regulation or compulsory legal request; (b) protect the safety of any person from death or serious bodily injury; (c) prevent fraud or abuse of Dropbox or its users; or (d) to protect Dropbox’s property rights. If we provide your Dropbox files to a law enforcement agency as set forth above, we will remove Dropbox’s encryption from the files before providing them to law enforcement. However, Dropbox will not be able to decrypt any files that you encrypted prior to storing them on Dropbox.
