You can see a list of apps that share you activity with facebook here (even if you didn't install any facebook app on your phone or didn't use facebook login feature) : https://www.facebook.com/off_facebook_activity/activity_list (click "Manage Your Off-Facebook Activity" on the right if you're on desktop)
Wow. I had no idea this existed. In my case, over 600 apps and services that I had no idea were connecting to Facebook. Is there no way to turn this off?
Clear your off-Facebook activity from your account?
Here are some things to know:
- Your activity history will be disconnected from your account. This does not currently include Oculus activity. We'll continue to receive your activity from the businesses and organisations that you visit in the future.
- Clearing your history may log you out of XXX and YYY other apps and websites. If this happens, you can still use Facebook to log back in.
- You'll still see the same number of ads. Your ad preferences and actions that you take on Facebook will be used to show you relevant ads.
