I'm a cybersecurity expert - here are the apps I would NEVER use

Many of the world's most popular apps have dubious terms of service, and exploit private data to make money, according to a cybersecurity expert. He says that by allowing data to be monitored by'big tech' companies, they can decide what we see online, and we become'defined by what computer algorithms decide for us.' Digital voice assistants such as Alexa are serious privacy risks, Gaffney says. The devices listen for'wake words' before operating but are listening to them all the time - and take snippets of your voice and process them in data centers far from your home. Gaffney says, 'I don't use them at all, but for those that do, I would not place them in the bathroom or bedroom. Though they wake on trigger words, they listen for a few seconds afterward.
