Correction: Host your users data outside of the country they reside in. The EU is just as bad about this as the US is - An unnamed EU nation ruled that all user data stored on servers in their jurisdiction and pertaining to users in their jurisdiction was subject to police investigation without warrant, subpoena, or the hosting provider to inform the users that their data had, or could be, accessed in this way. My company still runs a datacenter within that country - but we assure that no users that reside there also have their data stored there. Making it cross-jurisdictional, even a little bit - the user data is still in the EU - does wonders for privacy. I wish that the courts would rule cell phones and hosted services an extension of the human mind (and thus protected under the fifth), but I doubt I will ever see this. Too many people fail to see how vulnerable they are.
