Do you hear your smartphone?

They swear they didn't talk to anyone but that conversation, but all the time their cell phone was at the table.

Many consider the situation hypothetical, but many others testify to similar situations each day, arguing that phones have inside microphones that different apps have the right to use.

So far the forums on social networks are full of users who mention their experiences of encountering targeted advertising, for conversation themes they have made at the table.

Reporter Zoe Kleinman has written about this a technology report on the BBC network, for an even bigger case.

The woman had just been informed of the death of a friend. Later on, the suggestions for her online research and Google appeared just year, location, accident and the name of her deceased friend.

In many such cases this data collection is a violation of privacy. In 2019 the Belgian network V RT News, it owned 1,000 brother records from Google Assistt app, in which it had private information like addresses, names and people.

But is there such vast and frightening technology? David Lodge of Ken Munro, of Pen Test Partners, has created an app just for registrating everything close to the cell phone with an internal microphone.

In their interview with the BBC, they said their app could send personal ads to the user.

Meanwhile Facebook and Google, the two largest companies in this sector, deny collecting information in such forms.

Facebook, told BBC that it prevents companies from sending ads based on microphone information. But many other evidence shows that Google, like Amazon (Amazon Echo), really records us.

Google and other major technology companies draw up information for all of us and everything we do on the internet, since accounts, research, e-mail ads, according to what Google calls a personal <x0-perience” but this should not include voice records. /bbc
