Frequently Asked Questions (FAQ)

Q: Will this alarm work if I close my browser or shut down my PC?

A: No. This is a browser-based tool. You must keep this browser tab open and your computer must be "awake" (not in Sleep mode) for the alarm to work.

Q: Are my alarms saved?

A: Yes, your alarms are saved in your browser's local storage. When you return to this page on the same computer and browser, your list of alarms will still be there.

Q: How long does the alarm ring for?

A: The alarm will ring for 60 seconds (1 minute). After 1 minute, it will automatically stop, and the alarm will be toggled 'Off' to prevent it from ringing again on that same day.
