What we collect

Nothing. Box Breathing has no server, no account system, and no network requests. Your custom rhythm, sound and vibrate preferences, and your session history are all saved with localStorage, directly on your device, and never leave it.

No tracking

There is no analytics script, no ad network, and no third-party code of any kind running on this page. We have no way to see how you use the app, because nothing is ever sent to us.

Deleting your data

Clearing your browser's site data for this page erases your saved rhythm, preferences, and history immediately.
