The shift, prompted by Britain’s exit from the EU, will leave the sensitive personal information of tens of millions with less protection and within easier reach of British law enforcement.
The change was described to Reuters by three people familiar with its plans. Google intends to require its British users to acknowledge new terms of service including the new jurisdiction.
Ireland, where Google and other U.S. tech companies have their European headquarters, is staying in the EU, which has one of the world’s most aggressive data protection rules, the General Data Protection Regulation.
Google has decided to move its British users out of Irish jurisdiction because it is unclear whether Britain will follow GDPR or adopt other rules that could affect the handling of user data, the people said.
If British Google users have their data kept in Ireland, it would be more difficult for British authorities to recover it in criminal investigations.
The recent Cloud Act in the United States, however, is expected to make it easier for British authorities to obtain data from U.S. companies. Britain and the United States are also on track to negotiate a broader trade agreement.
Beyond that, the United States has among the weakest privacy protections of any major economy, with no broad law despite years of advocacy by consumer protection groups.
A Google spokesman declined to comment ahead of a public announcement.
