Vietnam’s National Competition Commission (NCC) has ordered VNG Corporation to revise its updated service terms for the Zalo messaging app due to user privacy concerns. The NCC emphasized that users should not be forced to consent to personal data collection as a condition for using the app and that consent mechanisms need to be voluntary and clear. The updated terms require users to accept all data management provisions or face account deletion within 45 days, which has led to significant user complaints and a decline in app ratings. Zalo's average rating on Apple’s App Store has fallen to around two out of five stars, and it has slipped to 59th place in download rankings, while international apps like WhatsApp and Viber have become more popular. Zalo has around 78 million active users and operates over 17,000 official accounts used by government and businesses. The NCC intends to meet with VNG to discuss the updated policy, as part of a wider regulatory trend against coercive data practices in digital firms globally.
