Learn About Facebook Privacy Settings Basics

Understanding Facebook's Privacy Control Structure

Facebook's privacy settings work through a layered system that gives you control over different types of information and who can see what you share. The main categories include profile visibility, post audience, friend request permissions, and data sharing with third-party applications. Each layer operates independently, meaning you can restrict one area while keeping another more open. For example, you might allow anyone to see your profile picture and name, but limit who can see your posts to only close friends.

The platform divides privacy controls into several key sections: "Privacy," "Blocking," "Apps and Websites," and "Your Facebook Information." Understanding how these sections work together helps you build a customized privacy approach. Facebook stores billions of pieces of information daily from its 3 billion monthly active users, so knowing where your controls are located matters significantly.

Your privacy settings determine three main things: who can contact you, who can see your content, and which companies or apps can access your data. When you first create an account, Facebook sets default privacy levels that tend to be moderately open. These defaults allow friends to see your posts, but may also let acquaintances or even strangers send you messages or view parts of your profile. Many users don't realize their defaults aren't set to their preferred level.

Facebook also distinguishes between "public" content, which anyone on or off Facebook can see, and "friends only" content, which only people you've added as friends can view. There's also a "friends of friends" option for certain settings, and custom lists that let you create specific groups with their own viewing permissions. Understanding these categories prevents surprises about who can see your information.

Practical Takeaway: Spend time exploring your privacy settings by clicking on your profile picture, then selecting "Settings and privacy" followed by "Settings." This shows you where all your controls are located so you can find them quickly when you want to make changes.

Managing Who Can See Your Profile and Posts

Your profile contains basic information like your name, profile picture, cover photo, and bio. You can control each element's visibility separately. To adjust who sees your profile information, go to Settings, then select "Privacy." Here you'll find options for "Who can see your posts," "Who can contact you," and "Who can look you up." Each setting has a dropdown menu with options like Public, Friends, Only Me, or Custom.

Post visibility is one of the most important privacy controls because it determines who sees what you share. When you create a post, you select an audience before posting. Your choices typically include: Public (anyone can see it), Friends (only people you've added as friends), Specific Friends (you create a custom list), and Only Me (just you can see it). Many users don't realize that posts created with Public visibility can appear in search results and be shared widely beyond their friends.

Facebook offers a "Limit Past Posts" feature under Privacy settings. If you've previously shared content with a broader audience and want to restrict it, this tool changes the visibility of old posts to "Friends only" automatically. This doesn't delete posts; it just limits who can see them going forward. According to Facebook's own data, about 45% of users have used this feature after realizing they'd shared content more openly than intended.

Your timeline can be customized to hide certain types of information from specific people. You can also control whether people can post on your timeline and whether tagged photos and posts appear without your approval. Many users enable "Review posts you're tagged in before they appear on your timeline" to prevent unwanted content from appearing on their profile.

One often-overlooked setting is your profile visibility to search engines. Facebook allows you to prevent search engines like Google from indexing your profile. If you disable this, your profile appears in search results when someone Googles your name. This setting is found under Privacy and has significant implications for how publicly visible your profile is beyond Facebook itself.

Practical Takeaway: Review your last 5 posts and check their visibility settings. Consider whether the audience you selected matches your intention. If you see posts set to Public that you'd prefer to restrict, use the three dots menu on each post to change its audience to Friends or a custom list.

Controlling Friend Requests and Contact Permissions

How people can contact you on Facebook depends on your friend request and messaging settings. Under "Privacy" settings, you'll find "Who can send you friend requests?" with options including Everyone or Friends of Friends only. Choosing "Friends of Friends" means only people who already know someone in your friend list can send you requests. This significantly reduces the number of requests from strangers or people without mutual connections.

Separate from friend requests is the ability to receive messages. You can allow messages from "Everyone," "Friends," or "Friends of Friends." Messages from people outside your selection go into a "Message Requests" folder rather than your main inbox. Facebook introduced this because studies showed that unrestricted messaging created problems for users who received unwanted contacts. About 35% of Facebook users report receiving unwanted messages, and proper settings can reduce this.

You can also control whether people see your email address or phone number on your profile. These are found in your basic information section and can be set to visible only to you, friends only, or public. Many users don't realize their phone number is viewable by default if they added it to their account. This is particularly important because phone numbers can be used to look you up across the internet or link to other profiles.

Facebook's "Do Not Disturb" feature works differently—it doesn't block people from contacting you, but it silences notifications while still receiving messages. This is useful if you want to take a break from seeing notifications but still want to respond to contacts later. You can schedule Do Not Disturb for specific times or use it temporarily.

The block feature represents the strongest contact control. Blocking someone prevents them from seeing your profile, sending you friend requests or messages, finding you in search, or seeing your activity. You can block someone by visiting their profile or through your blocking settings. Facebook doesn't notify the blocked person, but they may notice if they try to contact you and the request fails.

Practical Takeaway: Check your "Message Requests" folder to see if anyone is trying to contact you. This folder contains messages from people who aren't your friends. If you see requests from unknown people, this confirms your messaging settings are working as intended to filter unknown contacts.

Managing App and Website Permissions

Many websites and applications ask permission to connect to your Facebook account. This is convenient because you don't need to create separate usernames and passwords for each service. However, it also means those apps and websites can access certain information from your Facebook profile. Your "Apps and Websites" settings show which apps currently have permission and what information they can see.

When you connect an app to Facebook, you see a permissions screen listing what the app wants to access. This might include your name, profile picture, email address, friend list, or birth date. You should only grant permissions the app actually needs to function. For example, a photo editing app should never need access to your friend list, so if it requests that permission, it's a sign to reconsider connecting it.

Under "Apps and Websites," you can see your "Active apps and websites" and review what information each one can access. Many users are surprised to find apps they created accounts with years ago still have active permissions. Removing apps you no longer use reduces the number of places your data is stored. According to a 2023 survey, the average Facebook user had given permission to 47 different apps—many no longer in active use.

Facebook also has a section for "Expired apps," which shows applications you connected to but that are no longer active. These can usually be removed entirely. You should periodically review your apps list and delete ones you don't recognize or no longer use. Some apps continue to store your data even after you've removed access, but removing permission at least prevents them from continuing to gather new information about you.

The "Games, apps and websites" section includes options for whether your friends can see you've used a particular app. Some people prefer to keep their gaming activity or app usage private. You can also control whether apps can post to your timeline on your behalf—most security experts recommend disabling this so apps can't post without your direct action.

Practical Takeaway: Go to Apps and Websites and review your "Active apps and websites" list. Look for any apps you haven't used in the last three months and remove them. Pay special attention to apps with access to sensitive information like your friends list or email address
