Private messaging application Signal hit the top of both Apple and Google app stores after being installed 1.3 million times on Monday.
Signal utilizes end-to-end encryption to keep conversations secure, according to the website of the nonprofit Signal Foundation, the app’s developer. “We can’t read your messages or listen to your calls, and no one else can either. Privacy isn’t an optional mode—it’s just the way that Signal works. Every message, every call, every time,” it says.
High-profile users include Edward Snowden, the National Security Agency whistleblower, and business maven Elon Musk.
Another messaging app, Telegram, shot to number two in both major app stores.
“These types of shifts in messaging and social networking apps are not unusual,” Amir Ghodrati, director of market insights at App Annie, which analyzes apps, told news outlets in a statement. “Due to the nature of social apps and how the primary functionality involves communicating with others, their growth can often move quite quickly, based on current events.”
The surge in popularity for Signal and Telegram came after WhatsApp, owned by Facebook, alerted users that it was updating its terms and privacy policy. Facebook under the new policy reserved the right to share data it collected on users with other companies it owns.
Brian Acton, who used to work for WhatsApp, co-founded the Signal Foundation in 2018.
“As more and more of our lives happen online, data protection and privacy are critical. This isn’t just important for select people in select countries. It’s important for people from all walks of life in every part of the world. Everyone deserves to be protected. We created the Signal Foundation in response to this global need. Our plan is to pioneer a new model of technology nonprofit focused on privacy and data protection for everyone, everywhere,” Acton added.
