How to Block Porn in Chrome on Android, Incognito Included (2026)

To block porn in Chrome on Android, including incognito tabs, open Settings, find Private DNS, choose Private DNS provider hostname and type family.cloudflare-dns.com. Then in Chrome, open Settings, Privacy and security, Use secure DNS, and leave it on the default. Adult sites now fail to load in normal and incognito tabs alike.

Chrome on Android has no setting of its own to block adult sites, and it doesn't run extensions. So the block has to come from the phone. Below is the free setup, why incognito slips past most other methods, and how to make the block one you can't undo.

Why Incognito Gets Past Most Blocks

Incognito doesn't hide you from a filter. It only stops Chrome saving history, cookies and sign-ins on the phone. Two side effects of that matter:

• You are signed out. Settings tied to your Google account, such as SafeSearch, may not apply in an incognito tab.
• Nothing is left behind. Anything that works by checking history, or by someone looking at the phone later, sees nothing.

Neither one affects a block that works below the browser. Private DNS and a full blocker app filter the phone's connection, so an incognito tab is filtered the same as any other.

Step 1: Set Private DNS

1. Open Settings and tap the search bar.
2. Type Private DNS and open it.
3. Choose Private DNS provider hostname.
4. Type family.cloudflare-dns.com and tap Save.

This covers Chrome, incognito tabs, other browsers and apps, on Wi-Fi and mobile data. Other family hostnames are in our Private DNS guide.

Step 2: Keep Chrome on the Phone's DNS

Chrome can send its lookups its own way, which skips Private DNS. Check it once:

1. Open Chrome, tap the three dots, then Settings.
2. Tap Privacy and security, then Use secure DNS.
3. If a custom provider is chosen, switch it back to the default, Use your current service provider.

Step 3: Turn On SafeSearch

Private DNS stops adult websites from loading, but search results can still show explicit images. Open the Google app, tap your profile picture, then Settings, SafeSearch, and choose Filter.

Step 4: Check Incognito Is Blocked

1. Close Chrome fully and open it again.
2. Tap the three dots and open a New Incognito tab.
3. Try an adult site you know. It should fail with an error such as "This site can't be reached".

If it still loads, a VPN is probably on. Look for a key icon in the status bar.

Can You Turn Off Incognito in Chrome on Android?

Not in Chrome's own settings. On a child's phone, Google Family Link does it: Chrome on a supervised account can't open incognito tabs, and the parent can set Chrome to block explicit sites. On your own phone there is no switch, which is why the block has to cover incognito rather than remove it.

Where This Setup Breaks

• Private DNS switches off in a few taps. No passcode, no alert.
• A free VPN goes straight around it. It takes about a minute to install one.
• Another browser can skip it. Some come with a VPN built in.
• Chrome's own DNS setting can be changed back.

Every step above can be undone by whoever holds the phone, in about a minute.

QuitPorn: Chrome and Incognito Stay Blocked

With QuitPorn, you choose a lock from 1 day up to 365 days, and it can't be ended early. Our support team can't end it either. It installs from Google Play and works on Samsung, Pixel, Xiaomi, Tecno, Infinix, OnePlus and other Android phones.

During a lock:

• Chrome is blocked, incognito included, and so is every other browser. A new browser doesn't get around it.
• A VPN doesn't get around it.
• Nobody can switch it off. It can't be deleted until the lock ends.
• It ends on the date you chose, by itself.
• There is no passcode. On Android there is nothing to guess, write down or ask for.

One account covers up to 5 devices: Android, iPhone, iPad, Windows and Mac. Plans are $15 a month, $78 for six months, or $120 a year. If you haven't started a lock yet, you can get a refund within 7 days. See the plans.
