Your social media accounts know more about you than your closest friends. The platforms aren’t just storing your posts — they’re building detailed profiles, selling access to advertisers, and leaving your personal data exposed to anyone who knows where to look. If you haven’t touched your privacy settings in the last six months, you’re already behind.

A recent deep-dive from ExpressVPN’s blog on social media privacy lays out just how much control users are quietly handing over every single day — often without realizing it. The picture isn’t pretty. Default settings on most platforms are designed to maximize data collection, not protect you. That’s not an accident. It’s a business model.

The Default Settings Are Designed Against You

Let’s be blunt. When you create a new Instagram, TikTok, or Facebook account, the platform doesn’t ask what level of privacy you want. It assumes you want zero. Your profile is public. Your activity feeds the algorithm. Your location, device data, and browsing habits get hoovered up in the background while you scroll cat videos.

Most people never change a single setting. They assume the app is safe because everyone uses it. That’s exactly what these companies count on.

What You Should Actually Change Right Now

Stop treating this like a ten-step checklist and start treating it like damage control. Here’s what actually matters:

Go private on every platform. Yes, all of them. A public profile on LinkedIn might feel professional. It’s also a data harvester’s dream. Lock down who can see your posts, your followers list, and your activity status.

Kill location permissions. There is no good reason for Instagram to know you’re at a coffee shop in real time. Go into your phone’s app settings — not the app itself — and revoke location access entirely. Do it for every social app on your device.

Audit your connected apps. Every third-party quiz, tool, or service you’ve ever logged into with Facebook or Google still has some level of access to your account. Go to your security settings and revoke anything you don’t actively use. You’ll be shocked how many zombie connections are sitting there.

Turn off ad personalization. This won’t stop ads. But it limits how platforms build behavioral profiles around you. On Meta, it’s buried under Settings → Ads → Ad Preferences. Find it. Turn it off.

Two-factor authentication. Not optional at this point. Use an authenticator app, not SMS. SIM-swapping is a real attack vector and text-based 2FA is its favorite meal.

The Platforms Will Not Help You

Here’s the part the brand-safe tech blogs skip over: the companies behind these platforms have a direct financial incentive to make privacy settings hard to find, confusing to use, and easy to accidentally undo. Every setting you successfully lock down is money they’re not making.

Facebook has been fined billions across multiple continents for privacy violations. TikTok has faced congressional hearings over data practices. Twitter under every ownership structure has leaked user data repeatedly. These aren’t isolated incidents. They’re patterns. And the response from platforms is always the same — a press release, a minor UI tweak, and zero structural change.

The same instinct that should make you wary of forming emotional dependencies on AI chatbots should make you skeptical of any platform that profits from your engagement and attention. These systems are not your friends.

Your Data Doesn’t Just Live on the App

Here’s what most privacy guides miss entirely: the data you share on social media doesn’t stay on social media. It gets scraped, aggregated, and fed into people-search databases that anyone can access. Your name, city, approximate age, employer, relationship status — all of it ends up somewhere like BeenVerified within months of you posting it.

If you haven’t already looked into how to opt out of BeenVerified, that’s your next move after you lock down your profiles. Social media hygiene and data broker removal work together. One without the other is like patching one hole in a leaking boat.

And while you’re thinking about the broader digital footprint picture, the same logic applies to newer platforms. As augmented reality moves into more social spaces, the data collection surface area grows. Spatial data, biometrics, real-world behavior — all of it is coming. The habits you build now around privacy settings will matter exponentially more in that world.

The Hot Take

Privacy settings shouldn’t exist. The entire framework — where you have to opt out of surveillance one checkbox at a time — is broken by design. The correct default for every social platform should be maximum privacy, with users actively choosing to share more. Instead, we’ve accepted a system that puts the burden on victims while the companies profit. Calling this a “user education problem” is just a polite way of blaming you for getting robbed.

Take an hour this week. Go through every platform you use. Lock down what you can, revoke what you should, and stop assuming a popular app is a safe one. The data you protect today is the identity crisis you avoid tomorrow. That’s not paranoia — that’s just paying attention.

Your social media accounts know more about you than your closest friends do. Every like, every location tag, every message you’ve left on read is being catalogued, sold, and used against you in ways most people never bother to think about. The question isn’t whether your data is being harvested — it’s whether you’re going to do anything about it.

A recent deep-read from ExpressVPN’s privacy blog lays out a solid playbook for locking down your social presence. Some of it you’ve heard before. Some of it will make you want to delete everything and move to a cabin. Both reactions are valid.

The Platforms Are Not Your Friends

Let’s be honest about what these apps actually are. Instagram, Facebook, TikTok, X — they aren’t social tools with a side hustle in advertising. They’re advertising machines with a social interface bolted on. Every feature designed to make the app “more personal” is really designed to extract more data from you.

Location tagging? Great for memories. Better for building a profile of where you live, work, eat, and sleep. Those “memories” features that resurface old posts? Brilliant for engagement. Also brilliant for training AI models on your life story without your explicit consent.

This isn’t paranoia. This is the documented business model.

What You Can Actually Do Right Now

Lock Your Profiles Down

Start with the obvious: make your accounts private. Not semi-private. Not “friends of friends.” Private. This single step removes you from search results, stops strangers from screenshotting your content, and limits the blast radius if an account gets compromised.

While you’re in settings, audit your connected apps. That quiz you took in 2019 to find out which Hogwarts house you belong to? Still has access to your account. Every third-party app you’ve ever authorized is a potential leak point. Kill them all.

Stop Feeding the Algorithm Your Location

Turn off location services for every social media app on your phone. Do it now. There is no feature compelling enough to justify giving a corporation a live map of your physical movements. Post the photo. Leave the geotag off. The sunset doesn’t need coordinates to be beautiful.

Your Password Situation Is Probably a Disaster

If you’re using the same password across multiple platforms, one breach cascades into a full takeover of your digital life. Use a password manager. Enable two-factor authentication on everything. Use an authenticator app, not SMS — SIM-swap attacks are real and disturbingly easy to pull off.

Speaking of identity exposure, if you haven’t already checked out our guide to the best identity theft protection services tested in 2026, now’s the time. The overlap between social media breaches and identity theft is not a coincidence.

Think Before You Overshare

That photo of your new house. The post announcing you’re on vacation for two weeks. The birthday celebration that helpfully confirms your exact date of birth. Each piece of information you post is a brick in the wall someone could use to impersonate you, scam your family, or worse.

Social engineering attacks start with publicly available information. Attackers aren’t hacking into servers half the time — they’re reading your Instagram stories.

The Hot Take

Digital privacy literacy should be a mandatory part of public school curriculum, and the fact that it isn’t is a policy failure with consequences we’re only beginning to understand. We teach kids about stranger danger in physical spaces. We hand them smartphones at age ten and leave them completely unequipped to deal with the surveillance systems embedded in every app they download. By the time most people start caring about their privacy, they’ve already spent a decade pouring their lives into platforms engineered to exploit them. That’s not a personal failing. That’s a systemic one — and tech companies have benefited enormously from keeping it that way.

The Weird Truth About Privacy in 2025

Here’s the contradiction nobody wants to sit with: most people want privacy but don’t want to sacrifice convenience or connection to get it. That tension is exactly what social platforms count on. They’ve made sharing effortless and protecting yourself tedious by design.

The mental shift required isn’t technical. It’s attitudinal. You have to start treating your personal data like cash. You wouldn’t hand a stranger your wallet because they offered to show you a funny video. So stop handing platforms your behavioral data because their app is entertaining.

Technology moves in strange directions — sometimes AI reconstructs a Pompeii victim’s face from ancient remains, which is genuinely astonishing — but the through-line is always the same: data is power, and whoever holds yours holds a piece of your life.

You don’t have to leave social media entirely. But you do have to stop being passive about how much of yourself you hand over to systems that were explicitly built to take as much as you’ll give. Lock your settings. Audit your apps. Kill your location access. Treat every post like it might be public forever — because on the internet, it basically is.
