Elon Musk has a habit of sparking fires on Twitter. His latest suggestion to ‘Use Signal’ might have confused a few people – what is it, and why should I ‘use’ it?
Signal is, in short, a messaging app for people who are concerned about privacy: once-upon-a-time a concern of small group of techies, but now something that most people have good grounds to start taking seriously.
Signal is one of the first messaging apps that claims to hold absolutely zero data about you
Whenever you interact with anything – or anyone – online, some data is being passed round the internet; and some of that data can be personally identifiable to you. In practice, we trust this data to be handled well by the various companies that build these apps. An iPhone built by Apple makes a big deal out of privacy when you launch it – equally so does Facebook when you install the app.
