What does Facebook know about you?

Facebook may know more about you than the creepiest stalker could ever hope for. To make matters worse, this social media giant has failed to protect its user data over and over again. It’s time to discover what Facebook knows about you and take your privacy back.

What does Facebook know about you?

How much does Facebook know about you?

You may not even realize how much information Facebook has on you. The company behind Facebook, Meta, logs everything it can get its hands on, and its data collection is enormous. And as Facebook data leaks show, the company doesn’t always secure that information properly.

From personal information to your app activity – following is what Facebook knows about you.

Personal information

Facebook has a lot of personal information you’ve added to your profile voluntarily:

  • Your full name and birthday.
  • Places you’ve studied and worked at.
  • Places you’ve lived in.
  • Your email addresses and phone numbers.
  • Your relationship status.
  • Life events you’ve posted about, such as marriage, childbirth, or graduation.

If you’ve confirmed your identity, you also provided a photo of your ID to Facebook. While Facebook encrypts and stores it securely, it’s another piece of sensitive information that Facebook adds to its data collection.

All this data is a goldmine for Facebook and advertisers. And if most of it is available publicly, hackers and stalkers can take advantage of it too.

Activities on Facebook

When it comes to your activities, the platform has access to the following:

  • Calls you’ve made and messages you’ve sent on the platform. That includes your Messenger app unless you use the secret conversation feature for end-to-end encryption.
  • Your search history. Unless you regularly delete it, phrases, people, and videos you looked up over the years might be logged in Facebook’s servers. Search history includes your voice search history, with your voice recordings and their transcriptions.
  • Your posts, including anonymous posts in groups.
  • Photos and videos you’ve shared in your stories.
  • Reactions and comments you’ve added to posts on the platform.
  • Feedback and warnings you’ve gotten from group admins.
  • Polls you’ve created and voted on.
  • Events you’ve created and responded to.
  • Pages you’ve followed and groups you’ve joined.
  • Ads you’ve interacted with.
  • Your friends list, including those you deleted or whose requests you declined.
  • Your active and past sessions – when you logged in, and how much time you spent on the platform.
  • Times you deactivated your account and rejoined.
  • Your check-ins and other milestones.

Facebook collects a lot of data. If you look at your Facebook information, you may find things you’ve long forgotten about. But Facebook hasn’t.

Location history

Facebook tracks your location. When you log in, it identifies your location from the IP address of your device. That’s why you can get notified about “suspicious” devices when you travel or use a VPN to change your virtual location.

If you use any Facebook apps, they can track your location and create your location timeline based on the GPS data. Facebook can also figure out your location from events RSVPs, marketplace listings, and other check-ins. The company claims that your location history is private, but you must decide whether to trust it.

Devices and data on them

Facebook monitors what devices you’ve used to access their platform. This information can be helpful when you worry about your Facebook account being hacked since you can check where you’re logged in. But it’s useful for Facebook, too – the platform can use it for ad targeting, personalization, or to aggregate even more data about you.

When installing the Facebook or Messenger apps on your phone, Facebook also asks for app permissions, such as to access your phone’s contact list, camera, and microphone. It gives Facebook even more information about you, including people in your contacts.

Credit card details

If you’ve used Meta Pay (previously Facebook Pay) or ever paid for game subscriptions, goods from the marketplace, or Facebook advertising, Meta will process your payment card details. You’ll also be able to find the payment history in Meta’s Accounts Center.

Interests and opinions

Facebook deduces your interests and opinions based on your overall Facebook activity – the pages you liked, events you attended, and ads you clicked on. Facebook knows what music and movies you like and your religious and political views.

Previously, you could see what Facebook thought you liked on your profile, and it was accurate to the point of being creepy. You cannot view this information anymore, but it’s safe to assume Facebook still analyzes your data and activity.

The more accurate the interest information is, the more specific filter bubble and ads Facebook serves you.

However, problems arise when this psychological profile falls into the wrong hands. Malicious actors can use the Facebook feed and ads against you to change your opinion or manipulate you into doing things you may not have wanted to do.

Web and app activity

Facebook tracks your activity on its platform, whether you open it on your desktop browser or an app on your mobile device. It includes Messenger apps too, both the original and Lite version.

And since Instagram belongs to the same company as Facebook, Instagram activity also adds up to your profile. That’s why you can review data from both Facebook and Instagram on Meta’s Account Center.

Moreover, Facebook also collects information about the activity of apps and websites that you’ve connected to your Facebook account. And even when the websites and apps are not connected, the companies behind them may share your interactions with them with Facebook.

Companies that already have your data

Companies can upload your contact information (usually your email address or phone number) to Facebook for marketing purposes. Facebook matches these details with your profile and, as a result, shows or excludes you from seeing the company’s ads.

How does Facebook get information about you?

Facebook has many ways of getting information about you:

  • Information you provide. Everything you enter on your profile goes to Facebook servers as information about you. It starts with your email address or phone number and builds up from there.
  • Your activity on the platform. All your actions on the platform – from passively observing posts to reacting, commenting, and creating content – give Facebook lots of additional information and insights to deduce your interests and preferences.
  • Online tracking tools. As an advertiser, Facebook has many tools to track you on and off its platform. For example, Facebook can track your activity on websites that enable reactions or comments via Facebook or use Facebook for advertising. It can also use third-party cookies.
  • Other Meta services. Facebook collects data from its other apps and services, such as Instagram and WhatsApp. Information you share on any of its services contributes to the same user profile that Facebook uses for advertising.
  • Other companies. Companies can share information about you with Facebook to show you (or exclude you from seeing) their ads. For example, if you’re already a subscriber of a service, it could share your email address with Facebook, so Facebook won’t spend its money on showing ads to you.
  • External sources. Facebook can also receive information about you from other sources, such as data brokers or public records.

What does Facebook do with the information it collects about you?

Facebook collects information for various purposes:

  • Personalization and user experience. Facebook collects data to provide, personalize, and improve its service. It includes ad personalization and tailoring other content and recommendations to enhance your experience and thus make you stay on the platform longer.
  • Data analytics. As a part of the advertising business, Facebook uses data to measure and analyze your activity. Collected data helps Facebook to gain insights about trends and demographics for advertisers, marketers, and Facebook’s business partners.
  • Communication. Facebook uses some of the collected data to communicate with you. It involves sending notifications and personalized messages and keeping you informed about changes on the platform.
  • Security. Facebook gathers data to monitor and detect suspicious or harmful activities. The collected information can help determine if your Facebook account has been hacked.
  • Research. Facebook collects data to improve user experience or develop new features.

Can you stop Facebook from tracking you?

The only way to stop Facebook from tracking you is to delete your Facebook account permanently, deactivate Facebook Messenger, and stop using all Facebook services.

Facebook removes information it has on you only if you delete your account. And even then, it may continue getting information about you from other websites and apps.

How to control what Facebook knows about you

If you are not yet ready to delete your account, here are some tips to control the information Facebook knows about you.

Limit the information you add to the “About you” section

Most “About you” fields aren’t mandatory, so simply don’t fill them in. If you’ve already done it, you can remove that information.

  1. Click your profile picture and then your name.limit information on facebook: step 1
  2. Select “About” in the menu under your name and click the three-dot icon next to various information to edit it.limit information on facebook: step 2
  3. Review all the information you have on your profile. Add a fake birth date and remove your workplace and education or any other data that Facebook doesn’t need to know.

The less information available, the less Facebook will know about you. It can also help you protect your Facebook account from stalking, Facebook cloning, and other scams.

Limit other personally identifiable information

Similarly to the “About you” section, review other information you’ve shared with Facebook, including check-ins, photos, statuses, events, and life events.

It may take a while to go through these details, but if you want to limit your information on Facebook, it’s worth it.

Clear your past off-Facebook activity and disconnect future activity

Off-Facebook activity holds information on what you do even when you’re outside of the platform. It’s too much data for a company like Facebook to have, so clear your past activity and prevent Facebook from connecting it to your account in the future.

  1. Click your profile picture and select “Settings & privacy” > “Settings” > “Your Facebook information.”
  2. clear off facebook activity: step 1
  3. Click “View” next to “Off-Facebook activity.”clear off facebook activity: step 2
  4. Select “Clear previous activity.”clear off facebook activity: step 3
  5. Click “Clear” and then “Clear previous activity” once again to disconnect past off-Facebook activity from your account.clear off facebook activity: step 4
  6. Return to the “Off-Facebook activity” page and select “Manage future activity.”prevent off facebook activity: step 1
  7. Select “Disconnect future activity” and click “Continue.”prevent off facebook activity: step 2
  8. You’ll see a disclaimer about what turning off-Facebook activity means. Click “Confirm.”prevent off facebook activity: step 1

Review your ad preferences

It’s not possible to remove ads or their personalization on Facebook completely. But you can review your ad settings to limit personalization based on information from Facebook’s partners or your profile.

  1. Go to Meta’s Accounts Center and select “Ad preferences.”review ad preferences: step 1
  2. Click “Ad settings.”review ad preferences: step 2
  3. Open “Activity information from ad partners.”review ad preferences: step 3
  4. Select “No, don’t make my ads more relevant by using this information” and click “Confirm.” You’ll still get some personalized ads based on your activity on Facebook, but they won’t be based on your activity on other websites or apps.review ad preferences: step 4
  5. Go back to “Ad settings.” This time, open “Categories used to reach you.”review ad preferences: step 5
  6. Switch every toggle button to “Off” so Facebook won’t use your education, relationship status, or other information for personalized advertising. Alternatively, you can remove this information from your profile so that Facebook won’t have it in the first place.review ad preferences: step 6

Clear your search history

Your search history on Facebook may not be as sensitive as on Google, but it still reveals a lot of information about your interests, so it’s worth deleting it.

  1. Go to Meta’s Accounts Center and select “Your information and permissions.”clear facebook search history: step 1
  2. Open the “Search history” settings.clear facebook search history: step 2
  3. Click “Clear all searches.”clear facebook search history: step 3
  4. Select “All time” and click “Clear all searches” once again to delete your search history on all connected Meta apps, including Facebook.clear facebook search history: step 4
  5. Once you’re back in the “Search history” window, click “Keep searches for.”clear facebook search history: step 5
  6. Choose a period after which Meta should automatically delete your search history. By default, Facebook search history is kept for a year, but you can set it to “3 days” to protect your information.clear facebook search history: step 6
  7. Click “Confirm.”clear facebook search history: step 7

While you’ll stop seeing your search history within 24 hours, Facebook can still use it to personalize your experience for up to 90 days.

Manage your cookie settings

You can also change your cookie settings to limit personalization and tracking across apps and websites.

  1. Go to Meta’s Accounts Center and select “Your information and permissions.”manage cookies: step 1
  2. Open “Cookies.”manage cookies: step 2
  3. Click “Manage cookie settings.”manage cookies: step 3
  4. Deselect “Optional cookies” and “Cookies from other companies.”manage cookies: step 4

Deleting your cookies on the browser wouldn’t hurt, either.

Remove contacts you uploaded to Facebook

Have you used Facebook Messenger? Then Facebook may also have information on your contacts – consider removing it.

  1. Go to Facebook’s “Manage your uploaded contacts” page.deleting contacts from facebook
  2. If any contacts appear there, click “Delete all.”

Disconnect other apps and websites from Facebook

Many apps and websites let you log in via Facebook instead of creating a new account. Also, many apps connect to your account if you try various quizzes or games on Facebook.

While such logins are convenient or trying random games on Facebook may be fun, connected apps can become a privacy and security risk. Give Facebook less information about you and disconnect these apps and websites.

  1. Click your profile picture and select “Settings & privacy” > “Settings” > “Apps and websites.”disconnect apps and devices: step 1
  2. To check what data Facebook shares with third-party companies, click “View and edit.” Otherwise, click “Remove” next to each app and website to disconnect it.disconnect apps and devices: step 2

Review your app permissions

If you have any Facebook apps (Facebook, Messenger, Messenger Lite, or similar), Facebook may get lots of unnecessary information from your mobile devices. For example, the official Facebook app can access your calendar, camera, contacts, location, microphone, notifications, phone, and photos and videos.

Check app permissions and remove the ones that ask for unnecessary or sensitive data, such as your microphone and location. You can also limit some permissions to when the app is in use.

  1. Go to app settings on your mobile device (“Settings” > “Apps” on Android or “Settings” on iOS) and find Facebook, Messenger, and other Facebook-owned apps.remove facebook permissions: step 1
  2. Tap the app, and you’ll see permissions to which the particular app has access.remove facebook permissions: step 2
  3. Disable permissions that are not necessary for the app to function.remove facebook permissions: step 3

Use end-to-end encryption

Secure messaging apps provide end-to-end encryption. Messenger doesn’t offer it by default yet, but you can use end-to-end encryption to keep your messages private.

You can create encrypted chats in two ways.

  1. Open Messenger and tap the pen icon at the top-right corner.use secret conversation: step 1
  2. Toggle the lock icon before entering the name of the person you want to message.use secret conversation: step 2

Alternatively, you can switch to an encrypted conversation within your chats:

  1. Open Messenger and tap any current chat.use secret conversation: step 3
  2. Tap the “i” icon to open chat settings.use secret conversation: step 4
  3. Tap “Go to secret conversation.”use secret conversation: step 5
  4. Encrypted chat will appear as a new chat with a tiny lock icon next to it.use secret conversation: step 6

While the content of your messages will be encrypted, Facebook can still track who you talk to and how often. Moreover, end-to-end encryption is available on Messenger but not Messenger Lite.

Use a VPN to hide your IP and location

Another piece of information that Facebook knows about you is your IP address. It reveals your ISP, location, and the networks you connect to.

Fortunately, you can use a virtual private network (VPN) to hide your IP address from Facebook and other platforms. A VPN will also encrypt your connection to keep your browsing even more secure and private.

Online security starts with a click.
