Countdown Timer FAQ

Does the timer keep running if I switch tabs?: Usually yes, but background tabs or power-saving modes can delay updates and sound alerts, especially on mobile devices.
What do Auto Restart and Sound On do?: Sound On plays a local browser alert when time is up. Auto Restart immediately starts the same duration again after completion.
Are my settings saved?: Yes. The Sound On and Auto Restart options are saved only in this browser using local storage.
Does this timer send my countdown to a server?: No. Countdown values stay in your browser. The site may still load production analytics, but the timer does not upload your times.
Why does full-screen mode not open?: Some browsers, device modes, or embedded contexts block the Full Screen API. If that happens, the timer continues working in the normal layout.
