How to Make Your Facebook Profile Completely Private
Facebook is one of the most data-rich platforms on the internet, and by default, it shares more about you than most people realize. Whether you're concerned about strangers viewing your posts, advertisers tracking your behavior, or old contacts finding your profile, you have meaningful control over what gets shared — and with whom. Here's how the privacy system actually works, and what "completely private" really means on Facebook.
What "Completely Private" Actually Means on Facebook
True invisibility on Facebook isn't possible as long as you have an active account. Facebook itself retains your data for its own purposes, and certain information — like your name and profile picture — remains visible to anyone who finds your profile through search, even with strict settings.
That said, you can get remarkably close to private by locking down three distinct layers:
- What people see on your profile
- How people find you
- What Facebook does with your data internally
Each layer has its own settings, and they don't automatically affect each other. Changing your post audience to "Friends Only" does nothing to stop your profile from appearing in Google search results, for example.
Step 1: Lock Down Your Profile Visibility 🔒
Go to Settings & Privacy → Privacy Settings on desktop, or tap the menu icon and navigate to Settings → Privacy on mobile.
Key controls to change:
| Setting | Default | Recommended (Most Private) |
|---|---|---|
| Who can see your future posts | Friends | Friends or Only Me |
| Who can see your friends list | Friends of Friends | Only Me |
| Who can see the people and pages you follow | Public | Only Me |
| Who can look you up by email | Everyone | Friends |
| Who can look you up by phone number | Everyone | Friends |
| Do you want search engines to link to your profile | Yes | No |
The search engine indexing option is one of the most overlooked settings. Disabling it prevents Google and Bing from surfacing your Facebook profile in external search results.
Step 2: Audit Your Existing Posts
Changing your future post audience doesn't retroactively affect old posts. Facebook provides a "Limit Past Posts" option under Privacy Settings that bulk-changes all previously public or friends-of-friends posts to "Friends Only" in one action. This is a one-way change and can't be undone in bulk, so be deliberate about using it.
For individual posts you want restricted further — or deleted — you'll need to review them manually through your Activity Log (found under your profile menu).
Step 3: Tighten Profile Information
Your profile sections — including your workplace, hometown, education, and relationship status — each have their own audience controls. These are separate from post privacy. Go to your profile page, tap "Edit Profile," and review each section individually. Each field has a small audience icon you can click to restrict visibility.
Many people set their posts to "Friends Only" but leave their workplace and education listed as Public, which can reveal more than intended to strangers.
Step 4: Control Tagging and Timeline Posts
Under Settings → Profile and Tagging, you can:
- Require your approval before tagged posts appear on your timeline
- Limit who can post on your timeline (or turn it off entirely)
- Restrict who can see posts you've been tagged in
The Timeline Review and Tag Review features are essential if you want to control what others can associate with your account.
Step 5: Manage App and Third-Party Permissions 🛡️
Go to Settings → Apps and Websites to see every third-party app that has access to your Facebook data. Many people have dozens of forgotten connections — quiz apps, login services, games — still pulling data from their account.
Removing unused apps here doesn't delete data those apps already collected, but it stops ongoing access. This is one of the most frequently skipped steps in a real privacy audit.
Step 6: Adjust Ad Preferences and Off-Facebook Activity
Facebook's Ad Preferences settings (under Settings → Ads) let you limit how your data is used for ad targeting, including data collected from websites and apps outside of Facebook through the Off-Facebook Activity tool.
Clearing your off-Facebook activity history and turning off future tracking reduces the behavioral profile Facebook builds from your browsing habits elsewhere on the internet.
The Variables That Change What "Private Enough" Looks Like
How far you need to go depends on factors that are specific to your situation:
- Who you're worried about — casual acquaintances vs. data brokers vs. someone with your phone number all require different defenses
- How active you are — frequent posters face more surface area than someone who rarely posts
- What's already public — years of public posts, check-ins, and tags create a backlog that settings alone can't fully address
- Whether you use Facebook Login for other apps — each connected app is a separate data-sharing relationship
- Your device and platform — some settings appear differently or have different defaults on iOS, Android, and desktop
Someone who only uses Facebook to privately message family members needs a very different configuration than someone who runs a public page, participates in open groups, or uses Facebook Marketplace.
The right level of privacy lockdown depends entirely on what you're trying to protect, from whom, and how much of Facebook's functionality you're willing to trade for that protection.
