Limits and accuracy
A browser may delay sound or notifications in the background. The timer recalculates from its target end time when visible again, but closing the page ends reliability.
Privacy
Timer values stay in the page. Notification permission is controlled by the browser and notification content is not stored by WebToolMint.
Browser compatibility
Sound requires user interaction. Notifications, fullscreen and background execution vary by system.
Frequently asked questions
Will it ring while the phone is locked?
Not reliably. Mobile systems may freeze web pages, so use a system alarm for critical reminders.
Why are notifications unavailable?
The browser may not support them or permission may have been denied.
What happens while paused?
The remaining duration is preserved until you resume.
