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.
The migration was accelerated when, on January 7, Elon Musk urged his 40 million Twitter followers to install Signal in a tweet that likely stoked more interest in the end-to-end encryption messenger.
The growth of Telegram and Signal in China isn’t nearly as remarkable as their soaring popularity in regions where WhatsApp has been the mainstream chat app, but the uplift is a reminder that WeChat alternatives still exist in China in various capacities.
Signal amassed 9,000 new downloads from the China App Store between January 8 and 12, up 500% from the period between January 3 and 7, according to data from research firm Sensor Tower. Telegram added 17,000 downloads during January 8-12, up 6% from the January 3-7 duration. WhatsApp’s growth stalled, recording 10,000 downloads in both periods.
Sensor Tower estimates that Telegram has seen about 2.7 million total installs on China’s App Store, compared to 458,000 downloads from Signal and 9.5 million times from WhatsApp.
The fact that Telegram, Signal, and WhatsApp are accessible in China might come as a surprise to some people. But China’s censorship decisions can be arbitrary and inconsistent. As censorship monitoring site Apple Censorship shows, all major Western messengers are still available on the China App Store.
The situation for Android is trickier. Google services are largely blocked in China and Android users revert to Android app stores operated by local companies like Tencent and Baidu. Neither Telegram nor Signal is available on these third-party Android stores, but users with a tool that can bypass China’s Great Firewall, such as a virtual private network (VPN), can access Google Play and install the encrypted messengers.
The next challenge is actually using these apps. The major chat apps all get slightly different treatment from Beijing’s censorship apparatus. Some, like Signal, work perfectly without the need for a VPN. Users have reported that WhatsApp occasionally works in China without a VPN, though it loads very slowly. And Facebook doesn’t work at all without a VPN.
“Some websites and apps can remain untouched until they reach a certain threshold of users at which point the authorities will try to block or disrupt the website or app,” said Charlie Smith, the pseudonymous head of Great Fire, an organization monitoring the Chinese internet that also runs Apple Censorship.
“Perhaps before this mass migration from WhatsApp, Signal did not have that many users in China. That might have changed over the last week in which case the authorities could be pondering restrictions for Signal,” Smith added.
To legally operate in China, companies must store their data within China and submit information to the authorities for security spot-checks, according to a cybersecurity law enacted in 2017. Apple, for instance, partners with a local cloud provider to store the data of its Chinese users.
The requirement raises questions about the type of interaction that Signal, Telegram, and other foreign apps have with the Chinese authorities. Signal said it never turned over data to the Hong Kong police and had no data to turn over when concerns grew over Beijing’s heightened controls over the former British colony.
The biggest challenges for apps like Signal in China, according to Smith, will come from Apple, which is constantly under fire by investors and activists for submitting to the Chinese authorities.
In recent years, the American giant has stepped up app crackdown in China, zeroing in on services that grant Chinese users access to unfiltered information, such as VPN providers, RSS feed readers and podcast apps. Apple has also purged tens of thousands of unlicensed games in recent quarters after a years-long delay.
“Apple has a history of pre-emptively censoring apps that they believe the authorities would want censored,” Smith observed. “If Apple decides to remove Signal in China, either on its own initiative or in direct response to a request from the authorities, then Apple customers in China will be left with no secure messaging options.”
