Learn About Facebook Privacy Settings and Controls

Understanding Facebook's Privacy Settings Overview

Facebook's privacy settings are the controls that let you decide who sees your posts, photos, personal information, and activity on the platform. These settings exist because Facebook collects and stores a lot of data about its users. Understanding where these controls are located and what they do is the first step toward managing your online presence.

When you create a Facebook account, the platform sets default privacy levels for you. However, these defaults are not always the most restrictive settings available. Facebook's business model relies on showing your information to advertisers and other users, so the default settings often lean toward sharing more rather than sharing less. This means you may want to adjust them based on your own comfort level.

Facebook offers privacy controls in several main areas: who can see your posts, who can contact you, who can find your profile, and what information third-party apps can see. Each of these areas has multiple settings that you can customize individually. The settings are scattered across different pages within your account, which can make them confusing to locate at first.

Your privacy settings on Facebook are not permanent. You can change them at any time, and changes take effect almost immediately. This means you can experiment with different settings to find what works best for you. Some people prefer maximum privacy, while others are comfortable with more open sharing. Neither approach is wrong—it depends on your personal preferences and how you use the platform.

Practical takeaway: Start by visiting your Settings & Privacy menu on Facebook, then click "Settings." From there, you can navigate to the "Privacy" section to see an overview of your main privacy controls. Take time to explore each category so you understand what options are available to you.

Managing Who Can See Your Posts and Information

One of the most important privacy controls on Facebook is determining who can see the posts you share. Every post you create has its own privacy setting, and you can also set a default privacy level for all your future posts. This default applies unless you change it for a specific post.

Facebook offers several audience options for your posts. "Public" means anyone on the internet can see your post, including people who are not Facebook users. "Friends" means only people you have added as friends can see it. "Friends except" allows you to exclude certain friends from seeing a post. "Specific friends" lets you choose exactly which friends can see a post. "Only me" means the post is visible only to you.

Beyond individual posts, you can control who sees your overall profile information. Your profile includes your profile picture, cover photo, bio, work history, education, relationship status, and other details you have added. You can set different privacy levels for different sections of your profile. For example, you might make your profile picture public but keep your phone number visible to friends only.

Facebook also collects information about your activity on the platform, such as pages you like, groups you join, and posts you engage with. Some of this activity is visible to others by default. You can visit your Activity Status settings to control whether people see when you are online, when you last used Messenger, or when you were last active on the platform.

Your past posts may still have the privacy settings they had when you first shared them, even if you change your default privacy level. This means an old post set to "Public" will remain public unless you manually change it. Facebook offers a tool called "Limit Past Posts" that allows you to change the privacy setting on all your previous posts to "Friends" at once, though it does not change them to any other level.

Practical takeaway: Go to your Settings, click "Privacy," and look for "Who can see your posts?" Set this to "Friends" or "Friends except" if you want to limit who sees your new content. Then search your timeline for any very old posts you may want to adjust individually, or use the "Limit Past Posts" tool if you want to change everything at once.

Controlling Who Can Contact You and Search for Your Profile

Facebook allows you to control who can send you friend requests and messages. By default, anyone on Facebook can send you a friend request, and anyone can send you a message (though messages from non-friends may appear in a separate folder called "Message Requests").

You can change your friend request settings so that only friends of your friends can send you requests. This reduces the number of requests from strangers. To do this, go to Settings, click "Privacy," and find "Who can send you friend requests?" You can then choose between "Everyone" and "Friends of friends."

Message settings work differently. You cannot prevent people from sending you messages entirely, but you can filter them so that messages from non-friends do not clutter your main inbox. Messages from people you are not connected with appear in your Message Requests folder, and you can choose to ignore or delete them without reading. You can also block specific people from messaging you at all.

Your profile search settings determine whether people can find you by searching your name or other information. You can make your profile unsearchable on Google and other search engines by going to Settings, clicking "Privacy," and unchecking "Do you want search engines outside of Facebook to link to your profile?" This prevents your Facebook profile from showing up in Google search results, though people on Facebook can still find you if you are friends with someone or if they search directly on Facebook.

You can also control how you appear in search results on Facebook itself. Some settings allow only friends to find you in Facebook's search, while others allow anyone. This is different from Google search and controls whether people browsing Facebook can discover you.

Practical takeaway: Review your Settings under "Privacy" and look for "Who can send you friend requests?" and "Who can look you up?" Adjust these based on whether you want to limit contact from strangers. Consider unchecking the Google search option if you prefer your Facebook profile not to appear in internet search results.

Understanding Third-Party App and Website Permissions

Many apps and websites ask for permission to connect to your Facebook account. Examples include games, shopping apps, event planning tools, and restaurant apps. These apps want access to your Facebook information so they can personalize your experience or let you log in using your Facebook account instead of creating a separate password.

When you allow an app to connect to Facebook, you are granting it permission to see certain information from your profile. This might include your name, profile picture, email address, friend list, or other data. The app may also be able to post to your timeline or access information about pages you like.

Each time you give an app permission, Facebook asks you to review what information it will access. However, many people click "Allow" without carefully reading what permissions they are granting. Once an app has permission, it can access that information whenever you use the app, unless you later remove the permission.

To see which apps have access to your Facebook account, go to Settings, click "Apps and Websites," and select "Apps and Websites." You will see a list of all the apps and websites you have connected to Facebook. Next to each one, you can see what information it can access and when you last used it. You can click on any app to see more details or to remove its access entirely.

Some apps may continue to access your information even if you have not used them in months or years. For this reason, it is good practice to review your connected apps occasionally and remove any that you no longer use or that you are uncomfortable giving access to.

You can also control what information apps are allowed to see. When you first connect an app, you choose what permissions to grant. If you want to reduce an app's access later, you can sometimes do so through the app's settings, though some apps require full access to function properly.

Practical takeaway: Go to Settings, then "Apps and Websites," and review the apps that have access to your account. Remove any apps you no longer use or recognize. For the apps you keep, click on each one to see exactly what information it can access, and consider whether that level of access is necessary.

Managing Advertisements and Data Usage on Facebook

Facebook makes money primarily through advertising. The platform uses information about you—your interests, location, age, behavior, and more—to show you ads that are likely to interest you. Understanding how Facebook uses your data for advertising is important for protecting your privacy.

When you visit websites or use apps that have Facebook tracking code, Facebook collects information about your activity. This includes websites you visit, products you view, and links you click. Facebook uses this information to build a profile of your interests, even if you are not actively using Facebook at
