How to check if Facebook shared your personal data with Cambridge Analytica

Cambridge Analytica harvested personal information from 87 million Facebook users. Here's how to tell if you were affected.

Was your Facebook data shared with Cambridge Analytica? The political research firm harvested the personal information of roughly 87 million people to target American voters, using a personality quiz called “This Is Your Digital Life” that scraped the Facebook data of you and your friends. The revelation sparked big changes in the way Facebook handles third-party apps, and the social network recently started notifying users who had their information scooped up.

If you haven’t seen the prompt in your News Feed, you can check if your Facebook data was shared with Cambridge Analytica by logging into the network and visiting this help page. The section titled “Was my information shared?” explains whether your or your friends ever logged into the nefarious quiz, though it won’t name which friends handed over your data to the app.

While you’re at it, take the time to look over the other apps that you’ve granted access to your Facebook account, and disable any ones you no longer need. The Cambridge Analytica saga drives home how crucial it is to keep close rein on apps that hook into your social media accounts. Securing your personal data is more complicated than just running an antivirus suite and using a password manager to come up with unique logins for every site.

I’d recommend a Dell XPS 15 2-in-1 and the new Windows 10 to anyone who needs to get serious work done (before you kick back on your couch with your favourite Netflix show.)

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.
