Facebook: how to prevent apps from using your personal data

Facebook allows applications to access and use your personal data, with all the abuse this can entail. The Cambridge Analytica case proves once again that our data is valuable and can be used for malicious purposes. In this tutorial, we explain how to prevent Facebook from transmitting your data to third-party applications and better control the information you share on the social network.

Facebook is once again at the heart of a scandal. Donald Trump's team was able to use the personal data of 50 million Facebook users during the last US presidential campaign to analyze the behavior and opinions of voters and offer them content in line with their “unconscious prejudices”.

Facebook: prevent apps from accessing your data

The Cambridge Analytica affair made Facebook react: Mark Zuckerberg apologized and promised changes so that such a situation does not happen again. But without thoroughly questioning its marketing and advertising policies, it is unlikely that the social network will become more secure in terms of the protection of personal data. That's why this tutorial tells you how to prevent third-party apps from accessing and using your data.

To delete or modify application access on a case-by-case basis:

  • On Facebook, make sure you are logged into your account and go to Parameters
  • Select tab Applications
  • All third-party applications that have gained access to your Facebook account are listed. You can modify or remove the access permissions for the applications of your choice

It is also possible to deactivate any possibility of your data being collected by third-party applications. You will therefore be quiet on this side, but be careful: this prevents you from connecting to services via Facebook or from using certain apps. Here's the procedure to follow :

  • See you in Parameters then select the tab Applications
  • Below the list of all the apps linked to your Facebook account, find the section Applications, websites and modules And click Edit
  • Validate by clicking on Deactivate the platform

By doing so, you prevent third-party applications from collecting your personal data. On the other hand, Facebook itself continues to use all the information you share on the social network. If that does not suit you or more, we explain how to permanently delete a Facebook account.
