How to Protect Your Privacy on Social Media

Social media platforms connect us with friends, family, and the wider world, but they also collect staggering amounts of personal data. From your location and browsing habits to your political views and shopping preferences, the information you share can be harvested, sold, and exploited. Here is a practical guide to tightening your privacy on every major platform in 2026.

Why Social Media Privacy Matters

The stakes for unprotected social media accounts are higher than most people realize. Data brokers routinely scrape public profiles to build detailed dossiers that can be purchased by virtually anyone. This fuels several serious risks:

• Data harvesting: Platforms like Facebook, Instagram, and TikTok rank among the most privacy-invasive services, collecting data points that extend far beyond what you intentionally post.
• Identity theft: Criminals piece together your full name, birthday, employer, and location from social profiles to open fraudulent accounts or file fake tax returns.
• Stalking and harassment: Public location tags, check-ins, and real-time stories can reveal your whereabouts to bad actors.

Facebook and Meta Privacy Settings

Facebook collects more data categories than nearly any other platform. Fortunately, it also provides granular privacy controls if you know where to find them.

Essential Facebook Settings to Change

• Default audience: Go to Settings & Privacy > Settings > Default audience and switch from "Public" to "Friends" or "Only Me."
• Profile visibility: Under How People Find and Contact You, restrict who can look you up by email and phone number. Set each option to "Friends" rather than "Everyone."
• Search engine indexing: In the same section, toggle off "Do you want search engines outside of Facebook to link to your profile?" This prevents Google from surfacing your profile.
• App permissions: Navigate to Settings > Apps and Websites and remove any third-party apps you no longer use. Each connected app is a potential data leak.
• Privacy Checkup tool: Use Facebook's built-in Privacy Checkup (found in Settings & Privacy) to walk through your most important settings step by step.

Instagram Privacy Settings

Instagram shares much of its data infrastructure with Facebook, making privacy adjustments equally important here.

• Private account: Go to Settings > Account Privacy and enable "Private Account" so only approved followers see your posts.
• Story sharing: Under Settings > Privacy > Story, disable "Allow Sharing" to prevent others from forwarding your stories.
• Activity status: Turn off Show Activity Status under Privacy settings to hide when you were last online.
• Restrict tagged photos: Enable manual approval for tags under Settings > Privacy > Tags so tagged content does not appear on your profile automatically.

Twitter/X Privacy Settings

Twitter (now X) defaults to making most content public. You need to be proactive to limit your exposure.

• Protected tweets: Under Settings > Privacy and Safety > Audience and Tagging, enable "Protect your posts" so only approved followers see your tweets.
• Location data: Disable "Add location information to your posts" in the same privacy section. Also delete any previously stored location data.
• DM settings: Restrict who can send you direct messages to "People you follow" to reduce spam and social engineering attempts.
• Discoverability: Turn off the options that let people find you by email or phone number.

LinkedIn Privacy Settings

LinkedIn profiles often contain the richest professional data, making them a prime target for social engineering and phishing.

• Profile visibility: Under Settings > Visibility, control what is shown to non-connections and people not logged in to LinkedIn. Consider limiting your last name to an initial for public view.
• Connection visibility: Hide your connections list by toggling off "Who can see your connections" so that attackers cannot map your professional network.
• Profile viewing mode: Switch to "Private mode" under visibility options when browsing other profiles, so your viewing activity is not broadcast.

TikTok Privacy Settings

TikTok's algorithm is designed to surface content to the widest possible audience, which means you need to actively restrict access.

• Private account: Go to Settings > Privacy and toggle on "Private Account." Only approved followers will see your videos.
• Who can see your content: Set options for who can comment, duet, stitch, and download your videos. Restrict each to "Friends" or "Only Me."
• Personalized ads: Under Settings > Privacy > Ads, disable personalized ad targeting to reduce the data TikTok collects about your interests.

General Privacy Tips That Apply Everywhere

Beyond platform-specific settings, these habits will strengthen your privacy across all social media.

1. Audit app permissions regularly: Every few months, review which third-party apps and services have access to your social accounts. Revoke anything you no longer use.
2. Limit the personal information you share: Avoid posting your full birthday, home address, phone number, or workplace. Even seemingly harmless details can be combined to steal your identity.
3. Use strong, unique passwords with two-factor authentication: Use a password manager to generate passwords of 16 or more characters. Enable 2FA on every platform, preferring authenticator apps over SMS codes.
4. Be cautious with location sharing: If you must tag a location, do so after you have left. Disable real-time location features in stories and posts.
5. Separate personal and professional accounts: Keep personal content on private accounts that are not linked to your real name or employer.
6. Avoid public Wi-Fi for logging in: Public networks at cafes and airports can be exploited to intercept your credentials. Use a VPN if you must connect.

How PrivacyOn Helps Protect Your Social Media Privacy

Even with the tightest privacy settings, data brokers can still obtain your personal information through public records, past data breaches, and previously scraped social media profiles. These brokers compile your name, address, phone number, email, and more into searchable databases that anyone can access.

PrivacyOn continuously scans and removes your personal information from hundreds of data broker sites, closing the gaps that social media privacy settings alone cannot address. While you control what appears on your profiles going forward, PrivacyOn tackles the information that has already leaked into the data broker ecosystem. Together, strong social media settings and a service like PrivacyOn create a comprehensive privacy shield that keeps your personal data out of the wrong hands.

Taking 30 minutes to lock down your social media privacy settings today can prevent months of headaches from data misuse, identity theft, or unwanted contact tomorrow. Start with the platform you use most, then work through the rest. Your future self will thank you.
