You cannot block Facebook itself on TikTok, but you can stop Facebook from collecting data about what you do there

TikTok and Facebook are separate apps, so blocking one from your phone will not affect the other. What you can control is whether Facebook's tracking tools follow you across the internet and apps — including TikTok. Facebook owns a network of invisible trackers called the Meta Pixel and the Facebook SDK that sit inside thousands of websites and apps, including TikTok. These tools send information back to Facebook about what you click, watch, and buy, even when you are not logged into Facebook.

The good news: you have several ways to limit this tracking. The bad news: none of them are a single "block Facebook" button. Instead, you will adjust settings across three places — your phone's privacy settings, TikTok's own controls, and your Facebook account — to reduce how much data flows between the two platforms.

Key Takeaways

  • Facebook tracks your activity on TikTok through invisible code called Meta Pixel and the Facebook SDK, which you cannot see but can restrict.
  • On iPhone, turn off "Allow Apps to Request to Track" in Settings > Privacy > Tracking, then deny TikTok permission when it asks.
  • On Android, go to Settings > Google > Manage Your Google Account > Data & Privacy and turn off "Web & App Activity" to limit what Google and Facebook see.
  • In TikTok's settings, disable "Personalized ads" under Privacy > Ads to reduce the data TikTok shares with Facebook and other advertisers.
  • In your Facebook settings under Apps and Websites, review and remove apps and websites that have permission to see your data.

How Facebook tracks you on TikTok

When you use TikTok, Facebook's tracking code runs in the background whether you have a Facebook account or not. This code watches what videos you watch, how long you watch them, what you search for, and whether you click links. If you have a Facebook account, this information gets tied to your profile. If you do not, Facebook still builds a profile about you based on your activity across apps and websites.

TikTok shares this data with Facebook because Facebook pays for it — or because both companies benefit from the arrangement. Facebook uses the data to build a picture of who you are so it can sell more targeted ads to you on Facebook, Instagram, and other platforms. TikTok uses Facebook's tools to measure whether its own ads work.

This tracking happens through two main tools. The Meta Pixel is a piece of code that TikTok embeds in its app. The Facebook SDK (software development kit) is a larger toolkit that apps use to let people log in with their Facebook account or share content to Facebook. Both send data back to Facebook's servers constantly.

Blocking tracking on iPhone

Apple's operating system gives you a tool called App Tracking Transparency that lets you tell apps not to track you. When you turn this on, apps have to ask your permission before they can track your activity across other apps and websites. TikTok will still work, but it cannot send your behavior to Facebook without your consent.

Go to Settings > Privacy > Tracking. Toggle off "Allow Apps to Request to Track." This setting applies to all apps on your phone. When you open TikTok after this change, it will ask if you want to allow tracking. Tap "Ask App Not to Track." You will see this prompt only once per app, so if you have already said yes to TikTok in the past, you need to reset it.

To reset tracking permissions for TikTok specifically, go to Settings > Privacy > Tracking and scroll down to see which apps have permission. Find TikTok and toggle it off. The next time you open TikTok, it will ask again. Say no.

This does not stop TikTok from collecting data about what you do inside the app itself — TikTok still sees every video you watch and every search you make. It stops TikTok from sending that data to Facebook and other third-party advertisers outside the app.

Blocking tracking on Android

Android does not have the same built-in tool as iPhone, but Google offers something similar called Ads Personalization. Turning this off tells Google and apps that use Google's ad network not to build a profile of your interests based on your activity. This reduces — but does not eliminate — what Facebook can learn about you through TikTok.

Go to Settings > Google > Manage Your Google Account. Tap the Data & Privacy tab. Scroll down to "Web & App Activity" and toggle it off. You can also go to myactivity.google.com to see what Google has already collected and delete it.

For more direct control, go to Settings > Apps > Permissions and look for "Advertising ID." Some Android phones let you reset this ID or opt out of personalized ads here. The exact location varies by phone manufacturer, so search your settings for "advertising ID" if you cannot find it in the Permissions menu.

Neither of these steps stops TikTok from sending data to Facebook entirely, but they make it harder for Facebook to connect that data to your identity and use it to target ads at you.

Adjusting TikTok's own privacy settings

TikTok has its own controls for how much data it shares with advertisers like Facebook. These settings do not stop TikTok from collecting data, but they reduce what leaves the app.

Open TikTok and go to Profile > Settings and Privacy > Privacy > Ads. Toggle off "Personalized ads." This tells TikTok not to use your watch history and search behavior to target ads at you, and it reduces the data TikTok shares with Facebook and other ad networks to measure campaign performance.

You can also go to Profile > Settings and Privacy > Privacy > Restricted Mode and toggle it on. This filters out videos TikTok thinks are not appropriate for younger users, though it does not directly affect Facebook tracking.

Reviewing what Facebook already knows about you

Even with all these settings in place, Facebook may already have data about you from your past activity on TikTok. You can see what Facebook has collected and remove some of it.

Log into Facebook on a computer (the mobile app does not show all these options). Go to Settings > Apps and Websites. Under "Active" you will see a list of apps and websites that have sent data to Facebook. TikTok may not appear here by name, but you will see other apps and websites. Click on each one to see what data it has shared — usually things like your email, phone number, or list of friends.

You can click "Remove" next to any app or website to stop it from sending new data to Facebook going forward. This does not delete the data Facebook already has, but it stops the flow from that point on.

You can also go to Settings > Ads > Ad Preferences to see the interests Facebook has assigned to you based on your activity across the web and apps. You cannot delete these interests, but you can remove individual ones by clicking the X next to them. Facebook will rebuild them over time if you continue the same activity, so this is a temporary measure.

What these steps do and do not do

Turning off tracking on your phone, disabling personalized ads in TikTok, and reviewing Facebook's app permissions will significantly reduce how much data flows between TikTok and Facebook. You will see fewer ads targeted to your interests, and Facebook will have a less detailed picture of who you are.

These steps do not make you completely invisible. TikTok still collects data about what you watch and search for inside the app — that is how TikTok's algorithm works. Facebook may still receive some limited data from TikTok for measurement purposes, even with tracking disabled. And if you log into TikTok with your Facebook account, Facebook will always know when you use TikTok.

If you want maximum privacy, the most effective step is to avoid logging into TikTok with your Facebook account. Use your phone number or email instead. This breaks the direct link between your TikTok activity and your Facebook profile, making it much harder for Facebook to connect the dots.

Frequently Asked Questions

Can I log into TikTok with Facebook and still block Facebook from tracking me?

You can turn off tracking and personalized ads, but logging in with Facebook creates a direct link between your TikTok account and your Facebook profile. Facebook will always know when you use TikTok. For better privacy, create a TikTok account using your email or phone number instead.

Will turning off tracking stop TikTok from showing me ads?

No. TikTok will still show you ads, but they will be less targeted to your interests. You will see ads based on what you watch inside TikTok, not based on your activity across other apps and websites. TikTok does not have a way to turn off ads entirely unless you pay for TikTok Premium.

If I block Facebook on my phone, will it stop the tracking?

Blocking or uninstalling the Facebook app does not stop Facebook from tracking you on TikTok. Facebook's tracking code runs inside TikTok itself, not through the Facebook app. You need to adjust the settings described above to limit this tracking.

Does Facebook know what videos I watch on TikTok?

Facebook can see some information about your TikTok activity through its tracking tools, but the amount depends on your settings. With tracking disabled on your phone and personalized ads turned off in TikTok, Facebook sees much less. If you log into TikTok with your Facebook account, Facebook has more visibility into your activity.

What if I just delete my Facebook account?

Deleting your Facebook account stops Facebook from collecting new data about you going forward, but it does not affect TikTok's operation. Facebook may still have historical data about you from before you deleted your account. If you want to delete your data from Facebook, go to Settings > Your Information > Deactivation and Deletion and choose "Delete Account."
