Signal saw approximately 7.5 million installs globally through the Apple App Store and Google Play store between Jan. 6 and Jan. 10, according to Sensor Tower. That’s 43 times the number from the previous week. It is highest week or even monthly install number for Signal in the app’s history.
Meanwhile Telegram saw 5.6 million downloads globally from Wednesday through Sunday, according to Apptopia.
Signal claims to have “state-of-the-art end-to-end encryption” as part of its service, which prevents messages from being read by those who are not the intended recipient.
But starting Feb. 8, users will be prompted in the app to accept the updated terms in order to continue using WhatsApp. Users in Europe and the U.K. will see a different message due to data protection rules in those jurisdictions.
WhatsApp messages are encrypted, however, meaning Facebook will not be able to see their contents. But WhatsApp collects a lot of other data which can be shared with its parent company.
