WhatsApp vs Signal: Which Is Safer To Use Amid Data Collection Concerns
As compared to WhatsApp or Messenger, Signal collects no data whatsoever. The only personal data Signal stores is your phone number, and it makes no attempt to link that to your identity.
With the growing apprehensions, there has been buzz about switching to other apps like Telegram and Signal. Tesla CEO Elon Musk’s “Use Signal” tweet also led to a landslide signup for Signal app, which seems to be the most private messaging app and doesn’t collect any user data, as per the privacy details highlighted on the Apple app store.
Signal is a well-known privacy-focused messaging app, that is widely used by security experts, privacy researchers, academics, and journalists around the world. The Signal protocol also underpins WhatsApp’s end-to-end encryption, although one key difference is that Signal is open source, while WhatsApp is not.
The app store data shows that the Messenger app acquires the most data, followed by WhatsApp. The list of data both apps collect includes users’ purchase history, financial information, location details, contacts, phone number, email address, and usage data, among others.
Messenger, in addition to these, also collects your photos, videos and audio data, search and browsing history and other sensitive information.
