Frequently Asked Questions

How does the Alarm Clock play sounds?

The Alarm Clock uses the Web Audio API to generate alarm sounds directly in your browser. It offers five sound types — Beep, Chime, Bell, Digital, and Melody — each with distinct frequencies and waveforms. No audio files need to be downloaded.

Can I set multiple alarms at the same time?

Yes, you can create as many alarms as you need. Each alarm can have its own time, custom name, and sound selection. All active alarms are displayed in a sorted list and checked every second.

What is the snooze feature?

When an alarm rings, you can snooze it for 5 minutes. This postpones the alarm and updates its time, so it will ring again after the snooze period. You can also dismiss the alarm entirely to stop it.

Does the alarm work if I switch to another tab?

The alarm sound is generated using the Web Audio API and will continue playing even if you switch tabs. Additionally, if you have granted notification permission, the browser will show a desktop notification when the alarm triggers.

Is my alarm data stored or transmitted anywhere?

No. All alarm settings and sounds are handled entirely within your browser. No data is uploaded to any server, and your alarm information remains completely private and local.
