FAQ
Does the alarm ring if I close the tab?
No. The alarm runs in your browser, so the tab must stay open. You can minimize the window, but don't close the tab.
Are my alarms saved?
Yes, they're stored locally in your browser (localStorage). They are not sent to any server.
Why is there no sound at first?
Browsers block audio until you interact with the page. Press a button once and the alarm sound will work.
