Terms

Last updated 2026-08-31.

The app

Box Breathing is a free, client-side breathing guide. It runs entirely in your browser, keeps its data on your device, and doesn't require an account.

No medical advice

Box Breathing is a relaxation tool, not a medical device. It's general guidance, not a substitute for advice from a doctor, especially if you have a respiratory or cardiovascular condition.

Your data, your responsibility

Because everything is stored locally, clearing your browser's site data, switching devices, or reinstalling will erase your history and preferences, and we have no copy to restore from.

No warranty

Box Breathing is provided as-is, with no guarantee it will be available or work correctly at all times. We're not liable for anything arising from using the app.

Changes

We may update these terms or the app itself over time. Continuing to use the app after a change means you accept the update.
