Our devices can listen and watch us.

Smart speakers like Amazon's Alexa and Google Home can hear what we say to them, and sometimes even when we're not talking directly to them. Smart TVs and some apps can watch what we do on them. This is how they try to give us more personalized experiences, but it also means they have a lot of data about us. Think about all the times you've talked near your phone or TV - what if someone was listening?
