How to Block Roblox on Your Child’s Phone

Yes. On iPhone, Screen Time can control whether Roblox can be installed or opened; on Android, Family Link or equivalent supervision can do the same. Roblox also has its own parental controls for in-game chat, which a network filter cannot replace. DNS filtering can block many of the domains the Roblox app needs. That is intended to prevent or substantially disrupt live access; test the result on the child’s actual device. Use the phone controls for the app, Roblox account tools for chat, and DNS as a device-level backstop.

Parents searching for how to block Roblox are often dealing with two separate problems at once: the games, and the chat that sits inside those games. A DNS rule can stop the phone reaching Roblox’s online services. It cannot sit inside a Roblox account and rewrite who is allowed to type. The cleanest setup names both jobs, uses the matching tool for each, and tests the result on the actual handset rather than assuming the app icon disappearing means the account is gone.

Separate the app, the account, and the network

The Roblox app is what appears on the home screen. The Roblox account is what keeps inventory, friends and chat settings even if the app is deleted. The network path is what lets the app reach Roblox’s servers. You can close one of those doors and leave the others open.

If the family rule is “no Roblox on this phone”, start with app-install approval and an app limit. If the rule is “Roblox is allowed but free-text chat is not”, you need Roblox’s own parental controls. If the rule is “this device should not be able to reach Roblox even if the app is still there”, add DNS filtering. Mixing those sentences leads to a setup that feels strict and still fails a live test.

Use Screen Time or Family Link for the phone

On iPhone and iPad, Screen Time can require a parent for new apps, limit Roblox once it is installed, and lock those settings behind a parent passcode. Deleting the icon without locking installs often lasts until the next App Store visit.

On Android, Family Link can approve or hide Roblox and apply downtime. Check the child’s Google account and any second profile on the same tablet. A dual-space or second user is a common way a blocked Play Store app reappears without the original Family Link settings following it.

Use Roblox account tools for in-game chat

Roblox chat is controlled inside the Roblox account, not by the phone’s DNS setting. Roblox’s parental controls and account restrictions can limit who a child can message and whether free-text chat is available. That is the right layer if the concern is conversation rather than the games themselves.

A network block does not read Roblox messages, and it does not rewrite those account settings. If you leave the app allowed and only add DNS filtering, you still have not configured chat. If you configure chat and leave the phone able to install anything, a second device can ignore the phone rule. Do both when both problems are in scope.

Add DNS filtering when the app should not connect

Roblox is an online platform. Blocking the lookups it uses to reach its services is intended to prevent or substantially disrupt joining live experiences. Device-level DNS filtering can refuse those lookups on Wi-Fi and on cellular when the phone itself is configured to use the filtered resolver.

Because Roblox is a platform, it may use several hostnames and change details over time. Cached art or a previously loaded experience can linger briefly. Test whether the child can still play live on the actual handset, rather than assuming every asset will disappear immediately. DNS Parental Controls: A Simple Guide for Parents explains what that layer can and cannot do.

OathSafe protection is configured on the child’s device, so the same DNS policy can keep applying on Wi-Fi and cellular. You don’t need to configure the home router. If that device-level DNS policy is missing, the Roblox app can work again when the phone leaves home Wi-Fi.

Other places Roblox still runs

Blocking the phone does not block a Windows PC, an Xbox, or a friend’s device where the same Roblox account is signed in. If the family rule is about the child rather than one handset, say so and handle those other screens separately.

Voice and text also happen on companion apps. If Discord is part of the same evening routine, blocking Roblox alone may not match the boundary you described. How to Block Discord on Your Child’s Phone covers that adjacent path. How Kids Bypass Parental Controls lists other common workarounds, including a spare unfiltered device.

If Roblox starts working again

Test the current phone on cellular data. Look for a removed Screen Time passcode, a Family Link change, a deleted DNS profile or Private DNS setting, a VPN, or a second user on the tablet. Also check whether the child is simply on a different device that was never filtered.

Quiet DNS activity while the phone is charging overnight is not the same as Roblox being unblocked. Treat a protection gap as a reason to inspect the setup, not as a reconstructed play log.

Where OathSafe fits

OathSafe includes Roblox among the gaming services parents can block in App Controls. The block uses DNS filtering so the app has trouble reaching Roblox’s online services. OathSafe does not read in-game chat, does not change Roblox account permissions, and does not see the contents of a Roblox experience.

Trip Wire is designed to notice if that DNS protection appears to stop. It can prompt a parent to check the device. It does not identify which game was opened during a gap.

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

If I block Roblox with DNS, does that turn off in-game chat?

A DNS block aims to stop the app reaching Roblox’s servers. It does not edit Roblox account chat settings. If the app can still connect, chat is still controlled inside Roblox. Use Roblox parental controls for chat, and DNS when the phone should not connect at all.

Will deleting the Roblox app remove the child’s account?

No. The account remains on Roblox’s side. Deleting the app only removes it from that home screen until it is installed again. Pair deletion with install restrictions if you do not want it coming back.

Can a child keep playing Roblox on another device?

Yes. A phone-level block does not follow the account to a PC, console, or friend’s device. If the family rule is about the child, those other screens need their own controls.
