Your Social Media Privacy Settings Are Probably Wrong — Here's How to Fix Them
Most of us set up our social media accounts years ago, clicked through the setup screens as fast as possible, and never looked back. The problem is that the default privacy settings on most platforms are designed to share as much as possible — not to protect you. Here's a practical walkthrough of what to change.
Start with Facebook: The Most Data-Hungry Platform
Facebook's privacy settings are notoriously complex, but the most important ones are straightforward. Go to Settings & Privacy → Privacy Checkup. Set 'Who can see your future posts?' to Friends (not Public). Review your profile information — your phone number, email, and hometown should be visible only to you or friends, not the public. Turn off 'Allow search engines outside of Facebook to link to your profile' to prevent your profile from appearing in Google searches.
Instagram: Lock Down Your Account
If you're not a public figure or business, switching to a private account is the single most impactful change you can make. Go to Settings → Privacy → Account Privacy and toggle on Private Account. Also review which third-party apps have access to your Instagram account under Settings → Security → Apps and Websites. Revoke access to any apps you no longer use or recognize.
LinkedIn: You're Sharing More Than You Think
LinkedIn is a professional network, but it still collects and shares significant data. Go to Settings & Privacy → Data Privacy and review what data LinkedIn collects and shares with third parties. Turn off 'Profile viewing options' to browse anonymously if you'd prefer not to notify others when you view their profiles. Also disable 'Sharing profile edits' — otherwise your connections get notified every time you update your profile.
Twitter/X: Protect Your Posts
If you want to control who sees your content, enable 'Protect your posts' under Settings → Privacy and Safety. This means only approved followers can see your tweets. Even if you keep a public account, review what location information you're sharing — turn off precise location in posts and disable 'Personalization and data' settings that allow the platform to track you across the web.
The Settings Everyone Forgets
On every platform, review your connected apps and revoke access to any you don't actively use. Check your ad preferences and opt out of interest-based advertising where possible. And periodically download your data archive — it's eye-opening to see exactly what each platform has collected about you over the years.
Bottom Line
Privacy settings aren't a one-time task — platforms update their policies and interfaces regularly, so it's worth doing a review every six months or so. Set a calendar reminder and make it a habit.
