How To Discover Who Has Your Facebook Data and Cut Them Off

You might be logged in to dozens of hundreds of apps with your Facebook account.

These apps can see your friends list, your profile picture, networks you belong to and more.

Here’s how to find out which apps have data on you, and how to cut them off.

If’ you’ve ever opened an app and selected the option to “log in with Facebook” instead of creating a new account, chances are that the people or company behind that app know a lot about you. According to Facebook, each app that you log into will get your gender, networks you belong to, username, your user ID, your full name and your profile picture. They also get access to your full friends list and any other public info on your profile. And you may have used this method to log into apps a dozen or more times.

Cambridge Analytica data ┬áis a political research firm that was able to access data on more than 50 million Facebook users through a third-party personality quiz application without the knowledge or consent of users. The quiz maker wasn’t supposed to pass the information along, but Facebook had no technical measures in place to prevent it.


  • On desktop or mobile app, tap the drop-down menu on the top-right side of Facebook and select “Settings.”
  • Select the “Apps” option. This is on the left side of the page on desktop. On mobil, simply scroll down to the settings page.

This will show you all the apps that have access to the aforementioned data. To delete an app, just select it and tap the “X” button in the right corner, then select remove. Unfortunately, any data that you’ve previously shared will still be obtained by the app, but it won’t get any new data on you.

You can also manage settings for apps you still want to use. Instead of deleting a favored app, select the “edit” button while hovering over the app and then unchecked options that let it view my friends list and e-mail address.

    Anyone who thought that the info they were sharing on FB was in the slightest bit “secure” was delusional. There were plenty of warnings, loudly publicly announced in the popular news media for years, regarding the open nature of FB info. FB had its multi-page legal disclosures (barely comprehensible unless you were a lawyer); news outlets discussed the public nature of FB shared info; geek publications discussed the ready availability of vast amounts of personal info on users’ FB pages (and other internet sources as well). How can there be “shock” when the info is “mined” for any purpose? Clearly, every person surfing the internet is exposed to personally tailored commercial advertisements. Did anyone think about the sources of the info used to produce the custom ads? Perhaps the advertisers asked your mother for insights? Not!

    They use every bit of personal info available to target the ads, including FB. A couple of years ago, I received an email from Google touting their music streaming service. I had been using the service for awhile. As part of their braggadocio, they provided me with a list of every song that I had ever played using their service plus the number of times I had played it! I was stunned! Can you imagine the amount of data accumulated by Google by just its audio streaming service? They have that info on tens of millions of global users. A significant insight into personalities can be inferred just from that data. And Google (and many others) gather many types of personal information (preferred shopping sites; sources of news; etc). Incredible!

    My attitude? We are in a new age of info collection that is nearly unfathomable. It is impossible to fully “protect” your privacy, short of leaving society and becoming a hermit in the boonies of Wyoming (e.g., no credit cards, no bank accounts, no loans, live off the land as a hunter, gatherer – you get the picture). You can minimize exposure of personal info by carefully limiting visits to sites like FB and following the steps listed. Also, you can avoid shopping and reading news and other articles on the internet. In fact, you can totally avoid the internet. But then there is a cost-benefit to consider.
    The internet is an incredible resource that was unimaginable in our high school and college eras–I just turned 75. That vast resource has many cost-free components (just imagine a world without free email) but of course there is no “free lunch”. We pay for internet resources by providing information that is marketable, no different than exposure to advertisements that are interspersed throughout TV programs. And the internet is not the only source of personal info so avoiding the internet does not in any way guarantee privacy.
    As with every aspect of life, using our brain to understand the world around us is essential to successfully navigate our daily activities.

    Welcome to the new world!

    Thank you for your thought provoking response. I have to agree with you on most issues. As for your age, I to am in my early seventies and the internet would have been Godsend for several of my classes. Thanks again I really enjoyed your input.
