If you’ve ever wondered if your phone is spying on you, you’re not alone. One of the most hotly debated topics in technology today is the amount of data that firms surreptitiously gather about us online. You may well have shared the increasingly common experience of feeling creeped out by ads for something you recently discussed in a real life conversation or an online interaction.

This kind of experience has led to suggestions that tech firms are secretly recording our private conversations via smartphones or other internet-connected devices such as smart TVs, Amazon Echo or Google Home. Or that they are reading our private messages even when they are supposedly encrypted, as with Facebook’s WhatsApp.
