Signal saw approximately 7.5 million installations globally through the Apple App Store and Google Play Store between January 6 and January 1
Meanwhile, Telegram saw 5.6 million downloads globally from Wednesday to Sunday, according to Apptopia.
Signal claims to have “state-of-the-art end-to-end encryption” as part of the service, which prevents messages from being read by those who are not the intended recipient.
But from February 8, users will be asked in the app to accept the updated terms and conditions to continue using WhatsApp. Users in Europe and the UK will see a different message due to data protection rules in these jurisdictions.
However, WhatsApp messages are encrypted, which means that Facebook will not be able to see their content. But WhatsApp collects many other data that can be shared with the parent company.
This data includes account information, such as your phone number, transaction data, server-related information, information about how you communicate with others, including businesses when you use the service, and information about mobile devices.
In a Monday statement, WhatsApp said that this update does not affect the privacy of messages sent to friends and family. It clarified that the update will include “changes related to messages to a company on WhatsApp, which is optional, and provides additional transparency about how we collect and use data.”
WhatsApp says that the data shared with Facebook is used to improve infrastructure, promote security and safety and improve services by making suggestions or customizing features and content. This can also include integration between Facebook-branded products and WhatsApp.
Following the announcement, Tesla CEO Elon Musk urged his Twitter followers last week to “use Signal.”
Signal reported last week that verification codes sent to users via text message to start using the app were delayed due to high demand. Signal said more servers were added to handle the influx of new users.
“We continue to smash traffic records and add capacity as more and more people agree on how much they do not like Facebook’s new terms,” Signal said in a tweet. “If you have not been able to create a new group recently, try again. New servers are ready to serve you.”
Despite the increase in Signal and Telegram downloads, WhatsApp has not seen a decline, according to Adam Blacker, vice president of insight into Apptopia.
“It’s too ingrained. I guess there are a very small number of people who use WhatsApp every day who recently delete it,” Blacker told CNBC via email.
“Even those who download and use Signal or Telegram will continue to use WhatsApp, as this is where most of their friends and family are. They can start talking to certain people on Signal, but still chat with their mother on WhatsApp. . “
