Three things account for nearly every case:

• —Screen Time permission. Open iOS Settings → Screen Time and confirm Vallumn still has access. Without it, iOS refuses every block, and the app cannot force the issue.
• —Vacation mode. If it is on, every schedule and limit is deliberately stood down. It is on the Settings tab.
• —The apps in the rule. Selections are tied to one device, so a rule set up on another iPhone will look correct but contain nothing. Reopen the rule and pick the apps again on this phone.

Because Apple hands the app an opaque token rather than a list of apps, and that token only means something on the device that issued it. It is the same mechanism that keeps your selections private from Vallumn — and the cost of it is that block lists cannot sync.

iOS will not schedule a Screen Time window shorter than fifteen minutes, and it wakes the app’s extension on its own schedule rather than on the second. Vallumn closes the gap whenever you open it, which is why a short session sometimes tidies itself up the moment you come back to the app.

The block screen has a button that lifts the block for a length you choose in advance — anywhere from one to fifteen minutes, set on the Settings tab. iOS gives that screen no way to ask you at the time, which is why the length is a setting rather than a prompt. The apps shield themselves again when it is up.

Your strictness setting still applies: under Timeout the wait before the break grows each time you take one, and under Deep Focus it takes an Emergency Pass.

You choose an allowance of one to three passes per week. It is a rolling week, not a calendar one: each pass you spend comes back exactly seven days later, so it stays a scarce thing rather than something to wait out until midnight.

Turning it off is a request that lands 24 hours later. You can start it from the Settings tab, and you can cancel it during that window. Nothing shortens the wait — that is the entire point of it, and a version that could be talked out of would not be worth switching on.

If you need out sooner: deleting Vallumn removes every block it was holding. The app is friction, not a lock on your phone, and it is not trying to hold you hostage.

No. Vallumn is built on Apple’s Screen Time framework, which has no equivalent on Android — the app is not portable in any meaningful sense.

Nothing, and there is no plan to change that. If you want to chip in anyway, there is a donation page. It buys you nothing in the app, which is deliberate.

iPhone running iOS 17 or later. Screen Time permission is required — nothing can be blocked without it.
