If You Block an App, Can Your Child Still Reach It Through a Browser

Blocking Instagram's app and then finding instagram.com still loads in Chrome feels like the protection failed. It did not fail. It did exactly what app blocking is built to do, which is watch one specific app. A browser opening the same service's website is, to the phone, a completely different app doing a completely unrelated thing.

Why blocking one app does not also block the website version

Because an app blocker watches for a specific app being opened, not for a specific company or service being reached. Instagram the app and instagram.com opened in Chrome are two separate pieces of software as far as the phone is concerned, built by the same company but running as entirely different programs. Closing one has no connection to the other.

What is actually happening at a technical level

Every Android app runs isolated from every other app, under what Google's own security documentation calls a sandbox: "Android assigns a unique user ID (UID) to each Android app and runs it in its own process," enforced by the operating system itself, not by any single app's settings. A tool that closes an app when it opens can only ever recognize that one app's identity. It has no way to see, and no reason to see, that a browser just opened a website belonging to the same company.

Does this mean the fix is to block websites instead

Not quite, and it is worth being precise about what that would and would not solve. Blocking a specific website address inside a browser is a different mechanism again, one with its own gap: a restriction set inside one browser generally does not carry over to a second browser installed on the same phone. Blocking the app, restricting a website, and blocking the browser itself are three separate tools, each covering a different piece of the problem.

What happens if the browser itself is on the blocked list

That is where an app blocker's real strength shows up. A browser is, after all, just another app, and it can be chosen from the same block list as anything else. Block the browser during the hours a phone gets handed over, and it does not matter which site the child was trying to reach through it, the browser itself never opens.

So what should a parent actually do

Think in terms of the app that gets opened, not the service behind it. If an app is blocked but its website still worries you, the browser carrying that website is also just an app, and it can go on the same list. That single step covers every site reachable through it, rather than trying to predict and restrict one website at a time.

A blocked app staying closed and a browser staying open to the same service are not a contradiction. They are two different programs, and a phone only ever sees them that way.
