Quick reference
| Snooze | Yes — 5 minutes |
|---|---|
| Rings with the browser closed | No — a browser alarm needs the page or installed app open; use a native device alarm as backup for anything critical |
| Notifications and wake lock | Requested where the browser allows them |
| Data storage | In your browser only |
| Offline | After one successful visit, this route can reopen from the service-worker cache. Keep the tab or installed app open for sound and live state. |
A set alarm (time and label) is saved only in this browser, so it survives reloads and follows you to other pages.

About this alarm clock
The Clockfresh alarm clock is a free browser alarm for waking up, reminders, breaks and timed tasks — no ads and no account. Choose a time and a sound, arm it, and Clockfresh shows a live countdown and rings with a notification when it is due. The selected sound repeats until you stop or snooze it; the Repeat setting can limit it to one or three plays instead. It also requests notifications and wake lock where the browser allows them. For important wake-ups, keep the tab open and use a native device alarm as backup.
