Does AdvTimer support Pomodoro?

Do notifications work on all browsers?

Notifications depend on browser permissions and device settings. If they are blocked, enable site notifications in your browser first.

Where is my timer data stored?

Core app data is stored locally in your browser so your settings are available on the same device/browser.

Do you sell my data?

No. AdvTimer does not sell personal data. See our Privacy Policy for details.

The timer is not starting. What should I try?

1. Refresh the page
2. Check that JavaScript is enabled
