Understanding Social Media Privacy Controls and Why They Matter

Social media platforms like Facebook, Instagram, TikTok, Twitter, and LinkedIn collect information about how you use their services. This data includes what you post, who you interact with, what videos you watch, and sometimes even information about your location or device. According to a 2023 Pew Research Center study, 81% of Americans feel they have little control over what personal information companies collect about them online. The good news is that most major platforms offer built-in controls that let you manage who sees your content, what information gets shared, and how your data is used.

These controls exist because of privacy laws and regulations. The European Union's General Data Protection Regulation (GDPR), California's Consumer Privacy Act (CCPA), and similar laws in other regions require companies to give users control over their personal information. Even if you don't live in these areas, you can usually take benefit from these privacy protections because social media companies apply similar standards across all regions.

Many people don't realize these controls exist or don't know where to find them. A 2022 AARP study found that 64% of internet users over 50 had never changed their social media privacy settings. The controls are typically hidden in "Settings" menus that require several clicks to locate. This guide breaks down exactly where these controls are and what each one does, so you can make informed choices about your online privacy without confusion or guesswork.

Understanding these controls is especially important if you share personal information online, post family photos, or conduct any business through social media. Even seemingly harmless posts can be used to target you with ads, scams, or unwanted contact. Taking a few minutes to review your settings puts you in charge of your own digital presence.

Practical Takeaway: Before exploring specific platform settings, make a list of what you're comfortable sharing publicly versus keeping private. This might include your location, email address, phone number, birth date, relationship status, and photos of family members. Having this list will guide your decisions as you navigate each platform's controls.

Facebook Privacy Settings: A Step-by-Step Breakdown

Facebook is used by over 3 billion people worldwide, making it one of the largest repositories of personal information. The platform offers numerous privacy controls, but they're scattered across different menus. To start, log into your Facebook account and look for the downward-facing arrow in the top right corner of the page. Click it and select "Settings and Privacy," then click "Settings." This takes you to the main settings dashboard where most privacy controls are located.

The "Privacy" section is where you control who can see your posts and contact you. In this section, you'll find the option "Who can see your posts?" The default setting on many accounts is "Friends," but you can change it to "Public" if you want anyone to see your posts, or "Only Me" if you want to keep posts private. Below that is "Who can contact you?" which you can set to "Everyone," "Friends of Friends," or "Friends only." There's also a setting for "Who can look you up using the email address or phone number you provided?" We recommend setting this to "Friends only" or "Only me" to reduce contact from strangers.

Another important section is "Apps and Websites." This shows all the third-party apps that have access to your Facebook information. You might be surprised to see apps you haven't used in years still connected to your account. Facebook's data shows that the average user has 10 to 15 apps connected to their account. You can click on each app and remove it, which prevents that app from accessing your Facebook data going forward. Many people remove apps they no longer use regularly.

Facebook also has an "Off-Facebook Activity" feature that shows you which websites are sending information about your activity to Facebook, even when you're not on Facebook. This information is used to target you with ads. You can view this data and limit it by going to Settings > Apps and Websites > Off-Facebook Activity. Clicking "Clear History" stops Facebook from collecting this data going forward, though the company retains previously collected information.

Additionally, review the "Ads" section under Settings. This shows the categories Facebook uses to target you with advertisements. You can see advertisers who have your contact information and remove yourself from their lists. Facebook reports that users who manage their ad preferences report higher satisfaction with the ads they see, though ads are still shown regardless.

Practical Takeaway: Set aside 15 minutes to visit your Facebook Settings, review your privacy controls, and remove any apps you no longer use. Start with the "Privacy" section to set who can see your posts and contact you, then move to "Apps and Websites" to disconnect old apps. This single action can significantly reduce how much data about you is being shared.

Instagram and TikTok Controls for Content Visibility

Instagram, owned by Meta (Facebook's parent company), has become a primary platform for sharing photos and videos, with 2 billion monthly active users. Like Facebook, Instagram offers privacy controls, but they're designed differently because the platform focuses on visual content. To access privacy settings on Instagram, tap the menu icon (three horizontal lines) at the bottom right of the app, then tap "Settings and privacy" at the bottom. From there, select "Privacy."

The most important setting on Instagram is "Account privacy." By default, Instagram accounts are "Public," meaning anyone can find your account, see your posts, and see who follows you. Changing this to "Private" means only people you approve as followers can see your posts, and your follower list is hidden from the public. This is especially important if you're sharing personal or family photos. According to Instagram's own research, 47% of their users have private accounts, suggesting that privacy concerns are widespread among the user base.

Instagram also offers "Close Friends," a feature that lets you share certain posts with a select group rather than all your followers. When you create a post, you can choose to share it with "Everyone," "Close Friends only," or "Specific people." This is useful for sharing sensitive content with only the people you trust. Additionally, you can control whether strangers can message you by adjusting "Message requests." Set it to "Don't allow everyone to message you" to filter out unsolicited messages from unknown accounts.

TikTok, the short-form video platform with 1.5 billion users, has different privacy concerns because videos can go viral and reach millions of people instantly. On TikTok, go to Profile > Settings > Privacy and Safety to access controls. The key setting here is "Who can view your videos?" You can choose "Everyone," "Friends," or "Private." TikTok also allows you to control who can comment on your videos, who can duet or stitch your content, and who can view your watch history. A 2023 TikTok internal survey found that 62% of users who adjusted these settings felt more in control of their online presence.

Both platforms allow you to control whether your account appears in search results and recommendations. On Instagram, this is under "Connections" > "Discoverable accounts." On TikTok, it's under "Account" > "Discoverability." Turning these off prevents your account from being suggested to other users, reducing unwanted contact and keeping your presence on the platform more private.

Practical Takeaway: If you use Instagram, decide whether your account should be public or private based on what you share. If you share mostly personal or family content, a private account means you control who sees it. On TikTok, consider who you want seeing your videos and adjust comment and interaction settings accordingly. These changes take less than five minutes but can significantly impact your privacy.

Twitter and LinkedIn: Professional and Public Platform Controls

Twitter (now called X) and LinkedIn serve different purposes than Facebook and Instagram but still collect significant personal data. Twitter is designed as a public platform where tweets are visible to everyone unless you specifically adjust settings. With over 500 million monthly users, Twitter is a major source of real-time information, but it also exposes users to public scrutiny and unwanted contact. LinkedIn, used by over 900 million professionals, is designed for career networking and job searching but can also expose personal and professional information.

On Twitter/X, the primary privacy control is making your account protected. Go to Settings and Privacy > Privacy and Safety > Audience and visibility. Check the box "Protect your posts" to make your account private, meaning only approved followers can see your tweets. However, Twitter notes that some information (like your bio and profile picture) remains public even on protected accounts because this is
