How to block YouTube on iPhone and Android in 2 minutes with Defenras.

YouTube is the single biggest source of harmful content kids encounter online. This guide shows you exactly how to block it completely — across every device and every browser — in under 2 minutes using Defenras.

YouTube has become the internet's default channel for everything. For kids, that's a problem. Beyond the obvious risks of adult content, the bigger issue is the algorithm — YouTube Shorts in particular pushes a relentless stream of low-quality content, age-inappropriate material, and addictive engagement loops.

If you've decided to block YouTube, you need to know one critical thing: most blocking methods don't actually work.

Why "just deleting the app" fails

If you delete YouTube and think you're done, your kid is back on YouTube within minutes. Here's why:

• YouTube reinstalls in seconds from the App Store or Play Store
• youtube.com works perfectly in any browser — Safari, Chrome, Firefox, Brave
• YouTube links shared in iMessage, WhatsApp, Discord open in browsers, not the app
• Built-in iPhone and Android controls only cover one browser each — Safari on iPhone, Chrome on Android. Kids download other browsers to bypass.

To actually block YouTube, you need to block it at the network level — so it doesn't load in ANY browser or app, no matter what device, no matter what Wi-Fi. That's what Defenras does.

How to block YouTube with Defenras (2 minutes)

Step 1 — Install Defenras on your child's device

For iPhone or iPad:

1. Download Defenras from the App Store
2. Open the app and tap Install Protection Profile
3. Follow the prompt to install the DNS profile
4. Set a parent PIN your child won't be able to guess

For Android:

1. Download Defenras from Google Play
2. Open the app and tap Setup Protection
3. Allow the VPN permission when prompted
4. Set a parent PIN

Step 2 — Add YouTube to your block list

1. Open the Defenras parent dashboard at defenras.com/dashboard
2. Sign in with your parent account
3. Tap Custom Blocklist → Add Domain
4. Add these domains one at a time:
   • youtube.com
   • m.youtube.com
   • youtu.be
   • youtubekids.com (if you want to block YouTube Kids too)
5. Tap Save

Step 3 — Block the YouTube app (Android only)

If your child has the YouTube app installed on Android, Defenras can lock it behind a PIN:

1. In the Defenras app on your child's phone, tap App Blocker
2. Find YouTube in the list
3. Toggle it ON
4. The YouTube app now requires your PIN to open

That's it. YouTube is now blocked across every browser, every app, on home Wi-Fi, school Wi-Fi, and cellular data.

How to test it's working

On your child's phone, open any browser (Safari, Chrome, anything) and try to visit youtube.com. You should see a Defenras block page instead of YouTube.

If it loads, double-check that the DNS profile is installed (iPhone) or the VPN permission is granted (Android).

What about iPhone's built-in Screen Time?

Apple's Screen Time can block YouTube too — but only in Safari, and only if you add every YouTube URL one at a time. Kids find ways around it:

• Installing Chrome or Firefox where Screen Time filters don't apply
• Using youtube.com on a desktop browser they screen-mirror
• Working around adult-content filters that don't classify YouTube as adult

Defenras blocks at the DNS level — meaning it works regardless of which browser, which app, or how your child tries to access YouTube.

What about Google Family Link?

Family Link blocks the YouTube app on Android but does nothing about YouTube in browsers other than Chrome. Your child installs Firefox in 30 seconds and YouTube is back.

Defenras covers every browser automatically because it operates one layer deeper — at the DNS level, which every browser uses.

What else gets blocked when you install Defenras

YouTube isn't the only thing. Once installed, Defenras automatically blocks:

• Adult content — 287,000+ known adult sites
• Gambling sites — casinos, sportsbooks, crypto gambling
• Vape shops — over 12,000 e-cigarette retailers
• Scam and phishing pages — including fake Roblox generators
• Malware sites
• Predator-linked sites

And critically: it does all of this without collecting any data on your child.

How to talk to your kid about it

Don't just block YouTube without explanation. Try:

• Explain WHY: "YouTube's algorithm is built to keep you watching, not to help you. I want to limit how much it controls your attention."
• Offer alternatives: Specific videos you watch together, podcasts, audiobooks
• Set a renegotiation date: "We'll revisit this in 3 months and see how it's going"

The bottom line

Blocking YouTube on your child's phone takes 2 minutes with Defenras. Built-in tools cover one browser at best. Defenras covers every browser, every app, every network — and blocks 254,000+ other harmful sites at the same time, without collecting any data on your child.
