The Telegram messaging app was the top non-game app downloaded worldwide in January.
Video application TikTok was second overall and on top of the Apple store’s downloads.
Signal, Facebook, WhatsApp, Instagram, Zoom, MX TakaTak, Snapchat, and Facebook Messenger rounded out the overall top 10.
Telegram rose from number 9 in December 2020 to number 1. Telegram’s 63 million installs in January equaled 3.8 times its downloaded from January 2020, according to SensorTower.
TikTok, the most downloaded non-game app in December of last year, dropped one slot, while Facebook dropped two slots and WhatsApp dropped two slots.
“For the last 7.5 years we’ve consistently defended the privacy of our users and regularly improved the quality and feature set of our apps. Anyone who stays true to their values and applies focused effort over a long period of time is bound to succeed in their area. This is true for any human occupation—sport, blogging, art, coding, business or studying,” he wrote.
Signal’s rise was also dramatic, as it was not in the top 10 the previous month.
The encrypted messaging service, endorsed by U.S. intelligence whistleblower Edward Snowden, is run by an independent nonprofit. It’s also free and has no advertisements.
WhatsApp last month said it was delaying a planned change to its privacy policy, which would require the app to share user data with Facebook and Instagram.
WhatsApp and Messenger remain influential, though. They are used by nearly 2 billion people around the world, according to data tracking company Apptopia. Telegram has 46 million daily users and Signal has 13 million, the company said.
“WhatsApp and Messenger are so large that they are still going to maintain those users that are not concerned with privacy, and continue to attract those that don’t feel strongly on the matter. They are convenient apps to keep in touch with Grandma, for instance, and that won’t change,” an Apptopia spokesperson told Fortune.
