As fears over WhatsApp’s privacy policies send millions of users in the West to Signal and Telegram, the two encrypted apps are also seeing a slight user uptick in China, where WeChat has long dominated and the government has a tight grip on online communication.

Following WhatsApp’s pop-up notification reminding users that it shares their data with its parent Facebook, people began fleeing to alternate encrypted platforms. Telegram added 25 million just between January 10-13, the company said on its official Telegram channel, while Signal surged to the top of the App Store and Google Play Store in dozens of countries, TechCrunch learned earlier.
