### Implementation notes

Focus and break sessions start only when you press Start. Pause, reset or choose a different session at any time. Keep this tab open; background tabs and sleeping devices can delay the completion notice. No notifications or sound permissions are requested.

### Inputs and settings

No free-text input is required. Use the file inputs and/or settings below.

No additional settings are declared for this tool.

### Planning specification

Keep the tab open. A background tab or sleeping device can delay the completion notice; elapsed time is checked against a clock deadline. No automatic next session, sound or notification permission is used. Closing the tab resets the timer.

This describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.

## How to use it

Choose Focus, Short break or Long break. Adjust the duration if needed, then press Start. You can pause, reset or switch sessions without an account.

### A worked example

The default cycle starts with 25 minutes of focus, a 5-minute short break and a 15-minute long break. Sessions start only when you choose them.

### What to know

Keep the tab open. A background tab or sleeping device can delay the completion notice; elapsed time is checked against a clock deadline. No automatic next session, sound or notification permission is used. Closing the tab resets the timer.
