Lately I have been thinking about how to minimise the amount of data that Facebook can collect about me, and it has raised a few questions that I don't have the technical knowledge to answer. In particular:


  • Am I right in thinking that many popular web sites have elements that link back to Facebook which allow Facebook to track which sites you've been viewing?
  • If the answer to the above is yes, then can you mitigate it by ensuring that you log out of Facebook every time you use it?
  • If the answer to the above is yes, then would you also have to log out of the Facebook app on your phone as well as the web based interface?

I would be very interested if anyone has any thoughts on the above.

1) I'd say yes, regardless if you're using FB as your authentication for that site.


2) Log out and use incognito mode, I'd say yes.


3) No - if  browser is logged into something like Google , maybe but cant guarantee it.




But I could be completely wrong with my answers. 


If you're on Facebook, you have no real privacy is the way I look at it.

Having said that, I do use Facebook but crank my privacy settings to the max and review them regularly.

Many sites do include content from Facebook. While I am not familiar with the Facebook APIs, disabling acess under the "Apps and websites" settings on Facebook will minimise the amount of data available to third parties. This will also disable the ability to use Facebook to login to third party sites (a silly idea anyway, IMO).


Most modern browsers typically don't include referral information, so Facebook won't necessarily know what page you're browsing based on a request to Facebook servers alone unless there is a unique ID. Google Ads uses a unique ID for every site, so they probably do know more about your browsing than Facebook. I trust neither.


Even if you log out, any request to Facebook will pass their cookies, so you either need to delete those cookies or use a private browser instance to prevent them from sending information which could associate the request with your account.

I personally use both an iPhone (which restricts what Facebook can collect) along with Firefox with Facebook Container enabled.


I still need Facebook - it is my line of communication to multiple people and also convenient to have Messenger but hopefully by using Firefox I have severely limited what it can track on me.

+1 to either incognito mode or FireFox Containers. I also use EFF's Privacy Badger for however much that helps.


Really, you are the greatest threat to your data security. Most people (including me) can't be arsed signing in and out all the time or clearing cookies. Password Managers make it a bit easier to do though.


Don't worry, Google has you covered though... /s


Unfortunately, fingerprinting is where a lot of services are at though, which requires even more effort to evade.

To be honest If you still need to use Facebook and are really concerned for your privacy, then air gap facebook from the rest of your computing...


Grab old PC/laptop and make that your facebook machine,  don't do anything else on it......


Facebook and the like are so intrusive and I really don't expect them to even follow the rules they say the will. so simply don't trust them anywhere near anything else...

Even if you are not logged in and have never set up a Facebook profile, Facebook can create a shadow profile of you -


Like others have said, you can limit the ability for FB and others to track you but its pretty hard to completely avoid - there are literally 100s of trackers on the web building profiles of you -


You can probably tell from my sig that I'm not a fan of FB or any other company that uses your information as a product. Once you start digging into what these companies are doing it gets pretty scary. Check out Jaron Lanier's book 10 Arguments for deleting Social Media,

I only access Facebook within a Mint virtual machine and use the guest login which says everything is deleted when I log out of guest mode.


But then I only use facebook for some ev groups and have no friends..

Check out 'the great hack' on netflix.


Gives you a bit of the tech insight along with the political hoo-ha about how much every small Interaction, like, comment, thing you do builds a massively accurate profile of your digital self.


You build a corporate API 1-way communicated focused page, or you have a 'personal' one that is going to get exploited.

Thanks everyone - it's a fascinating subject.


I try to avoid Facebook and Google as their business model makes me really uncomfortable. Unfortunately many of my friends insist on communicating with me via Facebook so I can't quite bring myself to delete my profile so I'm just trying to work out how I can at least limit the damage.


Based on what I've understood of this, I think I will avoid using Facebook in any web browser and just sparingly use the iPhone app with all the dubious permissions disabled so it can't access my contacts or photos. I will also log out of Facebook from my web browser and delete their cookies. I'm sure it's not a perfect solution, but it'll do for now.
