Block yourself from using Facebook on an Android smartphone
Prevent yourself from using Facebook on an Android smartphone either permanently or temporarily

If you are trying to restrict yourself from accessing Facebook, you might have tried deleting the app only to find that you could easily reinstall it from Google Play and use it again.
You might have also noticed that it's possible to access the Facebook app from a web browser like Google Chrome, so deleting the Facebook app isn't always effective.
In this guide, we'll walk you through the Android instructions for blocking Facebook using approaches that work when you are trying to prevent yourself from accessing Facebook. We'll also go through strategies for permanent or temporary Facebook restriction.
Is it worth completely restricting yourself from using Facebook on your Android?
Here are a few of our top reasons why you might block Facebook, restricting yourself from accessing it entirely on an Android smartphone:
Inappropriate Facebook profiles can be difficult to filter out
Facebook profiles are often used to advertise adult content either subtly or blatantly. This can be a particular problem if you are trying to prevent yourself from seeking out or accidentally finding adult content.

Facebook might suggest inappropriate content
Facebook might suggest images or videos that you'd rather not see. Even if your profile preferences are adjusted to hide obvious explicit content, Facebook might still suggest content that can be a "stumbling block" for you.

Connecting strangers
The Facebook feed includes posts and reels from strangers, not just friends and connections. It's possible for you to connect with and private message them, which might be a problem for some people.

Use Supervised Mode to restrict Facebook
You'll then use Supervised Mode to block the Facebook app so that it can't be downloaded from the App Store or opened on the device. You'll also add facebook.com to the list of blocked domains so that Facebook can't be opened in Safari. Optionally, you can set up app time limits with Screen Time if you want to limit how long you can access Facebook without blocking it permanently.
Enable a DNS Content Policy
We recommend setting up a DNS Content Policy on your Android, which gives you more control over Facebook and other content. For example, you can use a default-deny approach to block all social media apps other than the ones you know to be safe. You can also schedule access to Facebook so that it's only available during certain times of the day.

A universal approach that can be used to block Facebook on Android to prevent yourself from accessing it is to use a DNS Content Policy

A DNS Content Policy disables the internet access for Facebook so that it can't function. The app can still be downloaded, but it will not work.
This approach comprehensively blocks Facebook from an Android smartphone since it restricts both the Facebook app downloaded from the Google Play Store and the version of Facebook that is available on the web through a browser like Google chrome.
Here's how it works:
Add a new block rule
In the Tech Lockdown dashboard, go to the Content Policy section and add a new block rule with Facebook selected

Customize the schedule
Select a schedule if you want to only block Facebook on specific recurring days and times. Otherwise, leave the schedule blank to block Facebook 24/7.

Specify who the rule applies to
Select an audience if you want to only block Facebook from specific people. Otherwise, leave the audience blank to block Facebook from everyone.

Connect Devices
Go to the Devices section of the Tech Lockdown dashboard and follow the setup instructions to connect devices to the Content Policy

Optional: Lock your Tech Lockdown Profile
If you are self-restricting access to Facebook, you can lock your Tech Lockdown profile so that you have to wait a certain amount of time before you can unblock Facebook.
