FAQ

Will the alarm work if my computer sleeps?

Browser alarms can be affected by device sleep, battery saver settings, muted audio, or closed tabs. Use a backup alarm for anything important.

Where are alarms saved?

Alarms are stored locally in your browser. They are not sent to a server by SleepEstimate.

Do I need to allow notifications?

Notifications are optional, but they help the alarm appear more clearly when the tab is not in focus.
