How to switch off Facebook platform apps (stopping Fb sharing more data through others’ use of apps)

It’s entirely possible that this is unnecessary. Apparently Facebook blocked apps that your friends were using from accessing your data back in 2014 (I only discovered this last week) so doing this now may be pointless, but I did this a few years ago, as well as blocking apps individually, and here’s how you do it.

  1. Log in to Facebook: on desktop / browser (don’t think you can do this on the phone app…?)
  2. Go to your App Settings page: (or use the on-screen menu to get there, using that little white arrow to the right of the question mark, then click on Settings, then Apps in the menu that will appear on the left).

  3. Click on each of the Edit buttons to change your settings to your preferences. As you can see from mine my preference is to switch things OFF.I have ‘Apps, Websites and Plug-ins’ disabled…

    I have ‘Apps, Websites and Plug-ins’ disabled – that’s the Platform Apps one, and when I click on ‘Edit’ here’s what my settings look like.

• Block quiz / test apps from accessing your Facebook information

AKA How to Switch of Facebook’s Platform Apps / Applications (see Supplemental).

Here’s what I posted on Facebook recently –

Your friends are the weakest link, mine too

Every time I spot that you’ve taken some test on Facebook and shared your results here I block the app that you used. This is because, when you authorise the app to interact with your page, it is then able to interact with mine* (and can, I assume from the wording below, access non-public information). Which I’d rather it didn’t. Obviously I will miss some because Fb won’t show me everything.

How to block apps etc

*because you can see my page and the app can access what you can access

If you scroll down that page there are several options for blocking or restricting various things. At the time of writing (Nov 2017) the list is

  • Restricted list
  • Block users
  • Block messages
  • Block app invites
  • Block event invitations
  • Block apps
  • Block pages

The last two are particularly useful for dodgy looking quizzes and tests. As far as I can tell when your friends take a test they authorise the app to access their page. Their page can access all your info, so my supposition is that the app can access all your info too. This is borne out in the format of the help text Facebook uses to clarify what happens when you block an app (in the picture above) – “Once you block an aapp, it can no longer contact you or get non-public information about you through Facebook.” Hmm, the ‘non-public information’ bit made me wonder, so I have blocked – over the years – over 260 of these apps I think, here is my full list.

It’s very simple to block, just start typing the name of the offending app and autofill options will appear (if not you’d need to visit the app’s page and see if you can work out who is behind it). If an app doesn’t show up in the Block Apps dialogue box try it in the Block Pages option lower down.

Of course once someone’s authorised an app it’s already (presumably) been able to harvest some of your info so you can request that individual app owners remove that data by contacting the developer directly. I have not done this, I probably should.. but…

I’ve realised that I’ve already switched off the Platform app setting on Facebook’s App Settings page. In the ‘Apps, Websites and Plug-ins’ panel on the left in the pic below mine says Disabled. For the ‘Apps others use’ panel on the right I’d previously unticked all the options so in fact this the subject of this post has probably never actually been a problem for me!
