How to Block YouTube on Your Child’s Phone

Yes. On iPhone, Screen Time can stop the YouTube app being installed or used; on Android, Family Link or equivalent supervision can do the same. YouTube Restricted Mode can reduce some explicit results inside Google’s own player, but it is not a full block. A device-level DNS filter can add a DNS layer that also covers youtube.com in a browser. Combine the layers, then test on Wi-Fi and mobile data.

YouTube is unusually easy to reach from more than one place: the official app, a browser tab, a signed-in Google account, and sometimes a shared tablet or TV in the same household. A parent who only hides the app icon can still leave the website open. A parent who only turns on Restricted Mode can still leave the full service reachable. The practical approach is to decide whether you want a time limit, a content-mode restriction, or a stop on the service itself — then apply the matching tools instead of hoping one toggle covers every path.

Decide what “block YouTube” should mean

Some families want YouTube gone for a younger child. Others want school-related videos to remain possible, with late-night scrolling reduced. Those are different jobs. App limits and downtime rules are better for “not all evening”. Removing the app plus blocking the website is better for “this phone should not reach YouTube”. Mixing the two without saying which outcome you want leads to a setup that looks strict and still leaks through a browser.

Write down the rule in ordinary language first: no YouTube app, no youtube.com, a 30-minute daily cap, or Restricted Mode only. Then pick tools that match that sentence. A DNS block will not create a tidy daily allowance. Screen Time will not, by itself, filter every YouTube hostname a browser might use.

Use the phone’s own controls for the app

On iPhone and iPad, Screen Time can require a parent for new downloads, hide or limit the YouTube app, and protect those settings with a passcode the child does not know. If the app is not installed yet, that approval step is usually the cheapest first move.

On Android, Family Link and some manufacturer tools can approve apps, set bedtime windows, and supervise the child’s Google account. Because YouTube is tied to Google, it also helps to look at the signed-in account on the phone: a child who can add a second unsupervised Google account may reopen YouTube even after you restrict the first one.

YouTube Kids is a separate app with a different catalogue. Blocking the main YouTube app does not automatically remove YouTube Kids, and the reverse is also true. Check both if the child’s age makes either one relevant.

Restricted Mode is not the same as blocking

YouTube Restricted Mode and similar SafeSearch-style settings try to hide some mature videos inside Google’s own player. They can be a reasonable extra layer when you still want educational clips available. They are not a promise that every unsuitable video is gone, and they do not stop the app or website from loading.

If your goal is that this phone should not reach YouTube at all, Restricted Mode is the wrong primary tool. Use it as a complement when you are allowing the service, not as a substitute for an app restriction or a DNS rule.

Add DNS filtering for the website and leftover app traffic

YouTube still depends on domain-name lookups to reach its services. Blocking those domains is intended to degrade the official app and substantially disrupt youtube.com in Safari or Chrome. That is useful when a child reinstalls nothing and simply opens a browser. Test the result on the child’s actual device.

OathSafe protection is configured on the child’s device, so it can continue applying on mobile data and other Wi-Fi networks. You don’t need to configure the home router. DNS Parental Controls: A Simple Guide for Parents explains that setup in plain English.

Video apps often use more than one hostname and may keep a short clip already stored on the device. Blocking YouTube-related DNS domains is intended to prevent or substantially disrupt live access, not to make every last thumbnail vanish in the same second. Apps can use cached data and changing infrastructure, so test the result on the child’s actual device.

Check the other screens in the house

A blocked phone does not block the living-room TV, a sibling’s tablet, or a school Chromebook. If the family rule is “no YouTube for this child”, say whether that means this handset only or every screen they can reach. Otherwise a careful phone setup can look like a failure when the child watched on a shared device that was never in scope.

For short-form video more generally, the same two-layer idea applies. How to Block TikTok on Your Child’s Phone covers a different app with a similar split between install control and network blocking.

If YouTube starts working again

Look at the current device, not last month’s screenshot. Has Screen Time or Family Link been turned off, was a DNS profile or Private DNS setting removed, did a VPN appear, or is the child signed into a different Google account? A live test on cellular data answers more than a conversation about intent.

A stretch of quiet DNS activity can also mean the phone was asleep, offline, or in Airplane Mode. That is a protection-gap question, not proof of what was watched. How to Know If Parental Controls Have Been Disabled walks through that distinction.

Where OathSafe fits

OathSafe includes YouTube among the streaming services parents can block in App Controls. The block is applied with DNS filtering. It does not watch the video stream, read search terms inside YouTube, or capture what is on the screen.

If the protected DNS path can no longer be verified, Trip Wire is designed to notice the protection gap and let a parent know it may need attention. It does not reconstruct a watch history for the time the gap lasted.

OathSafe is family internet protection for iPhone, iPad and Android. It uses DNS filtering to block unwanted online content and monitors whether that protection appears to stop. It can alert parents when protection cannot be verified, without reading their child's messages or browsing content.

Frequently asked questions

Does turning on YouTube Restricted Mode block the app?

No. Restricted Mode tries to hide some mature videos inside YouTube. The app and website can still load. Use app limits or DNS filtering if you want the service itself stopped on that phone.

Will blocking the YouTube app also block youtube.com?

Not reliably. The website is a separate path. If the rule is that this phone should not reach YouTube, combine an app restriction with a DNS rule that covers the related domains, then test in a browser.

Can a VPN reopen YouTube after a DNS block?

A working VPN can bypass some DNS-based filtering if it uses its own DNS path. Restricting new app installs and checking that the protected DNS setting is still present reduces everyday risk. No DNS-based service can guarantee that every already-installed VPN cannot connect.
