## FAQ

### Does the web timer send my break schedule anywhere?

No. The timer state lives in the browser tab, and your selected preset is stored locally on your device.

### Is this a medical recommendation?

No. It is a comfort habit aid, not medical advice or treatment.

### Can I share a preset?

Yes. Timer links can include focus and break values, such as ?focus=20&break=20, so you can reopen the same rhythm later.
