The quiz maker wasn’t supposed to pass the information along, but Facebook at the time had no technical measures in place to prevent it.
How to hunt them down
Here’s how to see what apps have your data and how to cut them off.
– On desktop or in the 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 mobile, simply scroll down the settings page.
This will show you all the apps that have access to the aforementioned data. In this case — and I had no idea until my editor asked me to write this story — I’ve granted access to 224 apps ranging from Airbnb to apps I don’t even remember, like “BarkApproved.”
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.
For Airbnb, for example, instead of deleting it I selected the “edit” button while hovering over the app and then unchecked options that let it view my friends list and e-mail address.
