SkieCan websites send notifications to managed student devices?
No. Skie blocks website notifications in Chrome through device owner policy, so no site can ask permission to send alerts and students cannot grant it. It is on by default. This stops adverts and distracting alerts reaching the lock screen of a school phone or tablet.
Browser notifications let a website send messages to a device even when the page is closed. They are a source of spam and sometimes of unsuitable adverts, and a student can be talked into tapping Allow without thinking.
Skie sets the Chrome notification permission to blocked by default and removes the prompt. The rule applies to every supported Chrome channel, which are stable, beta, dev and canary. A site cannot display the request, so there is nothing to allow.
This is a small rule with a visible effect during the school day. Tablets that are meant for lessons do not buzz with promotional alerts, and a hostel night schedule stays quiet. It also means the lock screen does not show previews from sites you have not vetted.
It does not affect app notifications. Apps on the allowed list can still show their own, such as a learning app reminding students of homework.
If you want to confirm the rule is active, the effective policy view lists it, and the compliance read-back confirms it on the device. Practical tip: when you walk teachers through a demo device, try to open a site that asks for notifications. The absence of the prompt is the easiest way to show the rule.
