Apple has begun keeping some of its Chinese users’ personal data in China, Reuters revealed yesterday. That’s significant because it is the first tech company to store information in the notoriously snoop-happy country, thus raising concerns that the data might be looked at by authorities. Apple is spinning the move as good news for users of its iCloud service, because it says it will help increase the speed and reliability of it. The rationale is that the closer customers are to the data centers, it will make it faster for them to access their stuff.
