China has banned mobile application operators from refusing to provide basic services to users who refuse to provide “unnecessary” personal information, according to what the China Cyberspace Administration announced in new rules in this regard. The rules identified “essential” personal information for 39 types of mobile phone applications, which include maps, car recall, online payments and shopping. The rules will go into effect on May 1, and the amendments come after information leaked through mobile phone applications has become a source of concern in China.
