Facebook has suspended accounts of British data analytics firm Cambridge Analytica and others in the wake of allegations of data theft, but that hasn't steered the world's largest social media platform away from controversies.

Several users are showing support to the growing movement to delete Facebook around the world. Even WhatsApp co-founder Brian Acton tweeted his support to the "#deletefacebook" movement, which protests against the way users' personal data is being collected and used.

But if you wish to continue using Facebook for its global social networking features, it's important to give your account's privacy settings a closer inspection. Facebook lets you control what type of data apps can access. Follow the step-by-step guide below to ensure apps aren't mining your personal data.

Step 1: Login to your Facebook account on a web browser

Step 2: Go to Settings from the top right drop-down menu

Step 3: Click on "Apps" on the left side menu

Step 4: Select each app to see what information you are currently sharing

Step 5: Edit the permissions by clicking the blue-and-white checkmark icons next to "info you provide to this app"

Step 6: If you do not recognize any app, simply click the "X" button and revoke all permissions at once

Another important setting is in the App Settings page, under the "Apps Others Use" box. Click on the "Edit" button to see what other Facebook users can see when they use the same apps. For instance, your birthday, current city, timeline posts can all be unchecked to add an extra layer of security.
