You don't have to delete your accounts to use them on your own terms. Most people leave the factory defaults in place for years, and those defaults were chosen to make you findable, shareable and easy to advertise to. Fixing that doesn't take a weekend. It takes an evening, a charged phone, and the patience to open menus you've never once tapped.

The goal isn't invisibility. It's deciding, per platform, who can see your posts, who can find you, and how much data flows out to advertisers and third parties. Here's how to run that sweep across Facebook, Instagram, TikTok and X, one app at a time.

Set Yourself Up Before You Tap Anything

Every platform buries privacy in a different corner, and labels shift with each redesign. If a menu name below looks slightly off, you're still in the right area. Look for the same words in a different order.

Three things are worth doing first:

• Write down your baseline. For each app, decide who your audience actually is: close friends, all followers, anyone with an account, or the open internet. Everything else follows from that one answer. If Instagram is your public portfolio but Facebook is for family, your settings should look completely different on each.
• Use the right device. Facebook and X hide more of their settings on the mobile app than on the desktop site, so if you want the full checklist, open a laptop for those two. Instagram and TikTok are the opposite: their app menus are now more complete than the browser versions.
• Charge your battery and your patience. You will be logged out of nothing, but you will hunt through nested menus. Set a timer for 90 minutes and treat it as one project rather than four separate chores you'll abandon halfway through.

Privacy settings decide who can see what. They do not decide what you choose to post. Do both halves of the job.

Facebook: The Longest Menu, Biggest Payoff

Facebook has collected more data for longer than any other app here, so this is where the audit matters most. Go to Settings & privacy, then Settings, then Audience and visibility.

Who can see and find you

• Who can see your future posts: set to Friends, or Friends except acquaintances if you keep a bloated friend list.
• Limit past posts: one tap retroactively changes everything you ever shared publicly to friends-only. This is the single highest-value button on the platform.
• Who can look you up using your phone number and email: set both to Only me. Otherwise anyone with your number can surface your full profile.
• Search engines outside Facebook: turn off. There's no reason your timeline should appear in a Google result.

Tagging, timeline and apps

Turn on Timeline review and Tag review so nothing appears on your profile until you approve it. Then check Apps and websites: every quiz, game and "sign in with Facebook" button you've ever tapped is still holding permissions. Remove anything you don't recognize or no longer use.

Finally, open Off-Facebook Activity. This is the list of purchases, web visits and app installs reported back to Facebook by other companies, and it is usually longer than people expect. Clear the history, then disconnect future activity so it stops rebuilding.

Instagram: Private by Default, Sensible by Choice

If you use Instagram to follow friends rather than build an audience, flipping to a private account solves most of this in one switch. Settings & privacy, then Account privacy.

• Story controls: hide your story from specific people, turn off story sharing to Facebook, and use Close Friends for anything you'd rather not broadcast.
• Tags and mentions: set who can tag you and who can mention you, and switch on manual approval for tags.
• Activity status: turn it off if you don't want people to see when you were last online.
• Comments: restrict commenting to people you follow, hide offensive comments automatically, and add custom blocked words for anything you never want to read.
• Ads: inside Accounts Center, open Ad preferences and turn off "Activity information from ad partners." This is what stops your off-app browsing from following you into your feed.

TikTok: Assume It's Public Until You Say Otherwise

TikTok's defaults lean hard toward discovery, and its settings live under Privacy and safety. Work through them in this order:

1. Private account: on, unless you're deliberately building an audience.
2. Suggest your account to others: off. This is the setting that pushes you onto strangers' feeds.
3. Who can comment, Duet, Stitch and send you direct messages: friends only, or nobody.
4. Who can view your liked videos and following list: only you.
5. Sync contacts and find friends: off in both directions. You don't want to upload your phone book, and you don't want to be suggested off someone else's.
6. Ads personalization: off, and check the section on data sharing with business partners.
7. Location: revoke precise location access in your phone's system settings, not just inside the app.

Also skim Filter keywords and Restricted mode. They won't protect your data, but they will protect your attention, which is arguably the point.

X: Small Menu, Two Big Switches

X keeps things lean. In Settings and privacy, then Privacy and safety:

• Audience, media and tagging: turn on Protect your posts if you want a locked account, and disable photo tagging and location information on every post by default.
• Discoverability and contacts: turn off letting people find you by email or phone number, and turn off contact syncing.
• Direct messages: limit incoming messages to people you follow.
• Ads preferences: switch off personalized ads and untick data sharing with business partners.

The Part People Forget: Sessions and Connected Apps

Changing visibility settings does nothing about a password you reused five years ago. Before you close the laptop, do this on every platform:

• Review active sessions and log out of any device you don't recognize. On X it's under Security and account access; on Facebook it's under Password and security.
• Turn on two-factor authentication using an authenticator app rather than SMS. Settings do not protect an account that can be taken over.
• Change your password if it's ever been used elsewhere, and make it unique here.
• Revoke third-party access one more time on Google and Apple sign-ins, since those can silently link back to these platforms.

A Realistic Ninety-Minute Schedule

1. Minutes 0–10: write your baseline audience for each app, turn on two-factor everywhere.
2. Minutes 10–35: Facebook, including limiting past posts and clearing Off-Facebook Activity.
3. Minutes 35–55: Instagram, via Accounts Center so you fix ads once across both apps.
4. Minutes 55–75: TikTok, working top to bottom through Privacy and safety.
5. Minutes 75–90: X, then a final pass on active sessions across all four.

What the Settings Can't Fix

Everything above controls distribution. None of it controls context. A photo of you in a private account is still visible to the friends who saw it, screenshot it, or reposted it. A tagged photo on someone else's public profile still shows your face and name. Event check-ins, workplace labels and "my year in review" posts all leak information you didn't mean to publish.

So finish the evening with three habits rather than three settings:

• Delay the geotag. Post the beach photo when you're home, not when your house is empty.
• Audit your profile pictures. They're public on almost every platform, even with a private account.
• Review quarterly. Settings reset, redesigns move things, and new features ship public by default. Fifteen minutes every three months keeps the whole audit from having to happen again.

You'll finish the evening with the same apps, the same friends and the same feed. What changes is that strangers, data brokers and advertisers no longer get the version of your life you never agreed to hand over.
