COMMON QUESTIONS

Frequently Asked Questions

Countdown intervals, browser alarms and audio configurations decoded
? How does the online timer work?
It schedules delta timestamp comparisons on tick intervals, triggering notifications when standard time runs out.
? Are my countdown tasks, alarms, or timers sent to cloud databases?
No. All interval timers, preset configurations, and sound triggers run inside your browser memory.
? Will the timer ring if my computer goes to sleep?
No. System sleep suspends JavaScript execution. Ensure your screen remains awake for active alarms.
? How do I pause or reset the timer?
Click 'Pause' to freeze the countdown momentarily, or 'Reset' to return values to initial states.
? Can I run multiple countdown timers at once?
Yes, you can add multiple ticking rows to track different activities side-by-side.
? Does the timer continue if I lose internet connection?
Yes. Since all scripts compile locally in your browser cache, the timer ticks perfectly offline.
