DH won an Amazon Alexa last year and it sit in the corner of our kitchen. DH kept turning if off as he was paranoid that it listened to our conversations (he works in an internet business and is very careful about his online presence etc). I said it was ridiculous so kept turning back on when listening to music then not bothering to turn it off again. However we are starting to notice we get adverts on facebook about things we have been discussing when at home (and not things we have googled either). For example DH and our builder were talking yesterday about getting some portable heaters as we are losing the central heating for a few weeks while we have a loft conversion done. 10 mins later he is getting adverts for heaters. Coincidence? Or is Alexa a spy sent to collect our data?
