Twitter has altered its privacy policies for non-US users and announced plans to move their data onto servers in Ireland.
The company did not mention any political intention behind the move, but it may be a reaction to the PRISM revelations which showed that the internet is full of intelligence agency backdoors.
"Starting 18 May 2015, users outside the US will receive Twitter services from Twitter International Company based in Dublin, Ireland," said the update.
"Twitter International Company will be responsible for handling your account information under Irish privacy and data protection law, which is based on the European Union's Data Protection Directive."
A short FAQ covers some of the problems that this might raise, and ultimately tells users that the Twitter experience remains consistent.
"As more people around the world use our services, we've expanded our operations to improve how we support our users globally," continued the update.
V3 asked Twitter whether the move was prompted by the PRISM scandal, but had not received a reply at the time of publication.
The privacy update confirmed that the company will hand over personal information when it is legally required to do so, and reminded users that "You are what you tweet!"
"We may preserve or disclose your information if we believe that it is reasonably necessary to comply with a law, regulation, legal process or governmental request; to protect the safety of any person; to address fraud, security or technical issues; or to protect Twitter's rights or property," it added.
Twitter's announcement comes as Microsoft is fighting court-approved US government demands for user data that it stores in Ireland.
Ireland's data protection minister, Dara Murphy, said last September: "Co-operation in the area of law enforcement is a fundamental element of our international relations, in particular with our partners in the US, which is why the issue of the transfer of the data itself is not objectionable, but rather the process that is being used.
"This would create significant legal uncertainty for Irish and EU consumers and companies regarding the protection of their data which, in this digital age, is everyone's most valuable asset."
Microsoft has the support of 28 technology and media companies, 35 computer scientists, and 23 trade and advocacy organisations, including Amazon, Salesforce, Rackspace, the Open Rights Group and the American Civil Liberties Union.
