Something interesting happened to me the other day. I was on a call and the person I was in conversation with, mentioned that there was a bottle of Hennessy on the desk they were on, fast forward and after the conversation, like 10 minutes later, I open up my Instagram and begin scrolling my timeline, disguised as a post (since they do that now), I spot a peculiar ad, a sponsored Hennessy post had shown up on my timeline.

Mind you, I have never searched or even interacted with anything “Hennessy”. This wasn’t the first time I have been served a targeted ad based on a conversation. The other time, I was chatting with my mother on WhatsApp and we were discussing some business that involved car hire, to my surprise, when I opened up Instagram, guess what sponsored post I see? Yup, one about hiring cars from some company I have never heard of.

Hennessy targeted ad on Instagram

To add to the creepy factor, I don’t have Facebook installed on my phone, I just use WhatsApp and Instagram, both of which have permission to use my phone’s mic. So, how is Facebook (When I say Facebook, I don’t mean just the social network but all its affiliate apps such as Messenger, Instagram and WhatsApp) able to show you targeted ads based on your conversations? Through your mic. Based on my personal experience, there are two things going on:

  1. Facebook is using your phone’s mic to listen in to your conversations and used certain keywords to serve you with relevant ads
  2. Facebook is also “reading” your conversations on WhatsApp to pick up keywords that it uses to serve you targetted ads.

A quick online research and I realized that reports of Facebook listening in to conversations started surfacing last year, around June. Quite a number of people came out accusing Facebook of showing them targeted ads based on conversations they were having in real-life. This prompted Facebook to release an official statement, denying these reports:

Facebook does not use your phone’s microphone to inform ads or to change what you see in News Feed. Some recent articles have suggested that we must be listening to people’s conversations in order to show them relevant ads. This is not true. We show ads based on people’s interests and other profile information – not what you’re talking out loud about.

We only access your microphone if you have given our app permission and if you are actively using a specific feature that requires audio. This might include recording a video or using an optional feature we introduced two years ago to include music or other audio in your status updates.

Well, after this statement was released, someone released a video on YouTube, where he claims Facebook started showing him “cat food” ads after he and his wife had a conversation about buying cat food, here’s the video, which was posted on July 29, 2016:

More than a year later and people are still claiming that Facebook is indeed listening in on their conversations, add me to that list now. On October 26, Rob Goldman, Facebook VP of Ads, said in a tweet that the company does not and has never used people’s mics for ads:

If I had not experienced these targeted ads myself, I would probably believe what Facebook is saying because they have more to lose by lying about it, then get caught pants down, than just coming out clean, but experience trumps faith and I now believe that Facebook and its affiliate apps do eavesdrop on their users in order to serve you targeted ads.


  1. Should we be worried about security? Like, if someone hacked your Facebook, can they use the mic to listen in on your conversations any time they want?

  2. This is a silly accusation after FB have denied it. Confirmation bias overload here. A simple deep-level packet inspection would give you the truth, and with EU privacy laws the way they are this would be enough to put a SERIOUS dent in Facebook if it was revealed. I just don’t believe it at all.

  3. I hope they are doing this to create a superior voice recognition system not just serving us adverts.I for one would like to my computer to type effortlessly as I dictate stuff.

  4. […] Facebook allegedly eavesdropping on you is the smartphone conspiracy theory that just won’t go away and so some computer science academics at Northeastern University decided to do a rigorous study to tackle it. They ran an experiment involving more than 17,000 of the most popular apps on Android to find out whether any of them were secretly using the phone’s mic to capture audio. The apps included those belonging to Facebook, as well as over 8,000 apps that send information to Facebook. Sorry, conspiracy theorists: They found no evidence of an app unexpectedly activating the microphone or sending audio out when not prompted to do so.
