Learn About Social Media Privacy Settings Guide

Understanding Social Media Privacy Basics

Social media platforms collect information about you every time you use them. This information includes what you post, what you like, who you follow, where you are located, and even data about your device. According to a 2023 Pew Research Center study, 72% of American adults use at least one social media platform, yet fewer than half understand how their information is being used.

When you create an account on platforms like Facebook, Instagram, TikTok, Twitter, or LinkedIn, you agree to their terms of service. These terms explain how the platform collects, uses, and shares your data. Most platforms use your information for targeted advertising, which means companies can show you ads based on your interests and behavior. This is how platforms remain free to use—they profit by selling access to advertisers who want to reach specific audiences.

Your privacy settings control what information is visible to other users and what data the platform collects about you. Different platforms have different default settings. Some platforms default to sharing more information publicly, while others are more restrictive. Understanding these differences matters because what you share on one platform may not be appropriate to share on another.

Data breaches represent a real risk on social media. Between 2020 and 2023, major social media platforms experienced multiple breaches affecting millions of users. In 2021, Facebook experienced a breach affecting 533 million users across multiple countries. These breaches exposed personal information including phone numbers, email addresses, and in some cases, more sensitive data.

Practical Takeaway: Before adjusting any privacy settings, take time to understand what information you currently share on each platform you use. Check what your profile looks like to someone who is not your friend or follower. Most platforms allow you to view your profile as a stranger would see it, which reveals what information is publicly visible.

How to Navigate Facebook Privacy Settings

Facebook is the largest social media platform globally, with approximately 3 billion monthly active users. Facebook's privacy settings are located in several different places within the platform, which can make them confusing to find. To access your main privacy settings on Facebook, click the downward-facing arrow in the top right corner, select "Settings and Privacy," then choose "Settings."

One of the most important Facebook settings controls who can see your profile information. In your privacy settings, you can choose whether your profile is visible to "Friends Only," "Friends of Friends," or "Public." Public means anyone on or off Facebook can see your profile, posts, and information. A 2022 survey found that 45% of Facebook users had their profiles set to public without realizing it. Your friends list, however, is a separate setting—you can hide your friends list from others even if your profile is public.

Facebook's "Who can contact you?" settings let you control who can send you messages. You can limit messages to friends only, or allow messages from anyone. Facebook also lets you control who can see your email address, phone number, and other contact information. Additionally, you can control who can tag you in posts and photos, and whether tags are visible in your timeline. Many users enable the setting that requires them to approve tags before they appear on their profile.

The "Apps and Websites" section shows which third-party apps have permission to access your Facebook data. Some apps request access to your friends list, location, or other information. Many users grant these permissions without understanding what data the apps receive. You can review and remove app permissions by going to Settings, then Apps and Websites. A practical approach is to remove apps you no longer use actively.

Facebook also collects data from websites and apps you visit, even when you are not on Facebook. This is done through Facebook's tracking pixel and the "Like" button that appears on many websites. In your off-Facebook activity settings, you can view and clear this data. You can also turn off the ability for Facebook to track your activity on other websites, though this may limit some features.

Practical Takeaway: Spend 15 minutes reviewing your Facebook privacy settings this week. Specifically, check three things: (1) who can see your profile by looking at your privacy settings, (2) which apps have permission to access your data, and (3) which posts are visible to friends only versus public. Remove permissions for any apps you no longer use.

Protecting Your Privacy on Instagram and TikTok

Instagram, owned by Meta (the same company as Facebook), has more than 2 billion users. Unlike Facebook, Instagram accounts are defaulted to public, meaning anyone can see your posts, followers, and following list. To make your account private, go to your profile, tap the menu icon, select "Settings and Privacy," then "Account Privacy," and toggle the "Private Account" option on. A private account means only people you approve as followers can see your posts and information.

Instagram's direct message settings deserve attention. By default, anyone can send you direct messages. You can change this to allow messages only from people you follow, or you can disable message requests entirely. Instagram also offers vanish mode for messages, which means messages disappear after they are seen, similar to Snapchat. However, vanish mode messages can still be screenshotted, which is an important limitation to understand.

TikTok, the rapidly growing video platform with over 1 billion users globally, has different privacy considerations than Instagram. TikTok collects extensive data about user behavior, including watch time, videos watched, likes, shares, and comments. In 2023, TikTok faced increased scrutiny from governments regarding data privacy and security. To adjust TikTok privacy settings, go to "Me," then "Settings and Privacy." You can make your account private, control who can message you, and manage who can see videos you like.

Both platforms allow you to control who can see your location. On Instagram, location is shown on posts you tag with a location, but you can untag locations or make specific posts visible to a limited audience. On TikTok, location data is collected but not automatically displayed on videos. Both platforms also allow you to control comments on your videos—you can disable comments entirely or approve comments before they appear publicly.

Hashtags on both Instagram and TikTok are searchable and indexed by search engines, which means posts with hashtags can appear in public search results even if your account is private. If you use hashtags, understand that your post may become visible to people beyond your followers. Being selective about hashtag use and knowing which hashtags are trending can help you make better choices about what you post.

Practical Takeaway: If you use Instagram or TikTok, check whether your account is set to private or public right now. If you prefer that strangers cannot see your content, switch to a private account and then approve followers manually. On TikTok specifically, adjust your direct message settings to limit who can contact you.

Managing Privacy on Twitter, LinkedIn, and Other Platforms

Twitter (now called X following its 2023 acquisition by Elon Musk) allows public tweets by default. Your profile, tweets, followers, and following list are publicly visible unless you specifically change your settings. To make your account private on Twitter, go to Settings and Privacy, select Privacy and Safety, and toggle "Protect your posts" on. When your posts are protected, only people you approve as followers can see your tweets. However, your profile information itself remains public.

Twitter has unique privacy concerns because the platform is often used for news, current events, and public discussions. Many people use Twitter professionally, which means their privacy preferences may differ from personal accounts. Twitter's search function indexes public tweets, meaning your public tweets can appear in Google search results and other search engines. If you do not want your tweets to be searchable, protecting your account is one solution, though it reduces visibility of your content.

LinkedIn, which has over 900 million users, is primarily a professional networking platform. LinkedIn collects employment data, educational history, job search activity, and profile viewing history. Your LinkedIn profile information is searchable by default, and your professional information is visible to other users. You can adjust visibility settings to control who can see your connections, activity status, and which profile sections are visible. LinkedIn also shows when you view someone's profile; you can make profile viewing private in your settings.

LinkedIn's data collection practices are particularly extensive because of its nature as an employment platform. LinkedIn tracks job searches, resume uploads, and interactions with job postings. According to LinkedIn's privacy policy, this information is used for recruitment targeting and advertising. You can adjust the visibility of your job search activity so that recruiters cannot see you are job searching. You can
