how to restrict websites on android

You've tried to block adult sites on your kid's Android phone, but somehow they keep finding a way around it. Or maybe you're trying to stop yourself from doomscrolling Reddit during work hours. Figuring out how to restrict websites on Android feels like a game of cat and mouse, and most people give up after the first failed attempt.

But here's the reality: there are four distinct methods that actually work, and each one suits a different scenario. As of 2026, Google's Family Link covers over 100 million child accounts, yet many parents don't realize it only filters web content inside Chrome and the Google app, it leaves other browsers untouched. That's exactly the kind of gap we're going to close.

Let's look at why most restrictions fail first.

Why Most Android Website Restrictions Fail (And How to Fix That)

Most people grab the first method they see online and assume it's bulletproof. That's rarely true. The biggest mistake is picking a solution that doesn't match the person being restricted.

For example, Digital Wellbeing is a built-in Android tool that limits app time. It does not block websites. Parents often turn it on thinking it keeps kids off adult content, but it can't stop a single web page from loading.

Another classic error: enabling SafeSearch in Chrome while the kid switches to Firefox or Samsung Internet and browses freely.

Then there's the bypass factor. A teen who wants around a block will try incognito mode, a free VPN, or even a simple proxy site. If your method only works inside one browser, they'll just use another.

If it relies on Wi-Fi, they'll switch to mobile data.

The fix is matching the method to the threat level and the user's tech skill. A young child needs something at the OS level. A teen needs a method that blocks across all browsers and data types.

For yourself, a lightweight browser extension might be enough. The rest of this guide walks you through exactly which approach fits your situation.

Quick Answer: What's the Best Method for You? (A 3-Question Check)

The best way to restrict websites on Android depends on who you're blocking and why. Here's the short answer: use Google Family Link for children under 13. Use a DNS filter for teens or yourself.

Use a browser extension for self-control on your own device.

Three questions to decide your path:

• Who is this for? A child, a teen, yourself, or a work device?
• Do they have admin access? If yes, they can undo most blocks.
• How tech-savvy are they? High skill means you need OS-level control.

Based on your answers, pick the method from the sections below. Each one has a different setup and bypass risk.

How Website Blocking Actually Works on Android – The 4 Main Approaches

Android gives you four basic ways to block websites. They range from simple browser tweaks to system-wide filters. Here's what each one does and where it falls short.

DNS-Level Blocking (Works Everywhere)

This method changes your phone's internet "phonebook" to a service that refuses to load certain sites. It's free, works on any browser, and even blocks some in-app ads. You set it once under Settings > Network & Internet > Private DNS.

But it only protects the device you configure, and a smart teen can switch it off if they know the settings menu.

Browser Extensions & In-App Controls

Firefox for Android supports extensions like uBlock Origin that can block specific URLs. Chrome's built-in SafeSearch blocks adult results but not actual sites. This approach is fast and easy for self-blocking, but it only works inside that one browser.

Anyone can install a different browser and bypass it.

Google Family Link (For Child Accounts)

Family Link is a free parental control app from Google. You create a child Google account and link it to your parent account. You can then set web filters that apply across Chrome, Google Search, and the Google app.

It also blocks apps, sets screen time, and requires parent approval for downloads. The limitation: it doesn't control third-party browsers, and older kids can sometimes work around it by signing into a different Google account.

Router-Level Blocking (For Home Wi-Fi)

You configure your home Wi-Fi router to use a filtering DNS service like OpenDNS FamilyShield. Every device on that network is blocked from adult or malicious sites. It's excellent for a whole family on home Wi-Fi, but it stops working the second the device leaves the house and uses mobile data or a friend's hotspot.

Decision Tree: Who Are You Blocking Sites For?

Your choice narrows down fast once you answer one question: who is holding the phone?

Branch 1: Restricting a Young Child (Under 13)

Go with Google Family Link. It's free, built for kids, and ties to their Google account. Set up a child profile on your parent phone, apply web filtering, and enable SafeSearch.

For extra safety, use whitelist mode, only pre-approved sites load. The child cannot disable it without your parent account password.

Branch 2: Managing a Teen's Phone

Teens will test boundaries. A single method won't hold for long. Use a combination: enable Private DNS with a filtering service (like Cloudflare 1.1.1.3 for malware and adult content) and pair it with Family Link for account-level controls.

Also block the installation of VPN apps via Family Link. Expect that some bypass attempts will succeed, so have an honest conversation alongside the tech.

Branch 3: Blocking Distractions for Yourself

You don't need heavy parental controls. Install Firefox and add the uBlock Origin extension. Customize a block list for sites like Reddit or YouTube.

Or use Digital Wellbeing's Focus Mode to pause distracting apps. These methods are quick, reversible, and work well for short-term self-discipline.

Branch 4: Enforcing Policy on a Work or School Device

This requires Managed Google Play and an Android Enterprise profile. IT admins can push a managed browser with a strict allowlist of sites. Only pre-approved URLs load.

The user cannot install other browsers or change DNS settings without admin permission. This is the only truly locked-down option.

Step-by-Step: Set Up Google Family Link (Best for Kids)

Family Link is the most reliable free method for kids under 13. You need two phones: one for yourself (parent) and one for the child. Both must run Android 7.0 or newer.

Download the Family Link app on both phones. On your phone, open it and tap "Create a child account." Follow the prompts to create a new Google account for the child. You'll enter their birth date, this sets the age-based restrictions.

What Family Link Can and Can't Block

Family Link filters content inside Chrome, Google Search, and the Google app. It blocks websites by category (adult, violent, illegal). You can also add specific URLs to a blocklist or allowlist.

What it cannot block: websites opened inside a third-party browser like Firefox, Samsung Internet, or Opera. For full coverage, you'd need to restrict which browsers the child can install, which Family Link does let you do via app blocking.

Enabling Web Filtering + SafeSearch

Open the Family Link app on your phone. Select your child's profile. Tap "Controls" then "Content restrictions." Under "Google Chrome," choose "Manage sites." You can select "Block adult sites" or "Only allow approved sites." Also enable "SafeSearch" under the Google Search section.

This hides explicit results from searches. Turn on "YouTube restricted mode" separately if your child uses YouTube.

The Whitelist vs. Blacklist Trade-Off

Whitelist mode means only the sites you specifically allow will load. Everything else is blocked. This is safest for young children, but it's a lot of work, you must add every educational site, homework resource, and entertainment site they use.

Blacklist mode blocks a predefined set of adult categories and lets everything else through. That's easier but gives less control. Our research shows most parents start with blacklist, then switch to whitelist around age 8 when the child begins independent browsing.
