Breath Work

Privacy Policy

Effective November 6, 2026 · zhuwei lu

Your breathing history stays on your device. We do not receive your sessions, calm ratings or motion data.

Breath Work is operated by zhuwei lu, who is responsible for the app, user support and privacy requests described in this policy.

1. The app

Breath Work stores completed sessions, optional calm ratings and preferences locally to show your practice history and insights. Device motion is used only to animate the stars and is not saved. Turn off Moving stars in Reminders, or use iOS Reduce Motion, to disable this effect.

The app has no accounts, advertising, analytics, tracking, third-party SDKs, backend or AI processing. It does not access HealthKit, your microphone, camera, contacts or location. Audio is bundled in the app.

2. Optional reminders

Notification permission is optional. Reminders are scheduled locally by iOS. You can turn them off in the app or iOS Settings without losing access to breathing exercises. iOS controls notification delivery, including Focus and Scheduled Summary.

3. Retention and deletion

Local history remains until you delete the app from your device. Offloading the app keeps its data. Device backups may retain app data under your Apple backup settings; manage or delete those backups separately in iOS Settings. We do not operate cloud sync or receive a copy of your history. We cannot recover or delete data stored only on your device.

4. Support correspondence

If you email us, we receive your email address and the information you choose to send. We use it to answer your request, troubleshoot problems and handle privacy questions. Do not send passwords, verification codes or unnecessary health information. Correspondence is kept as needed to resolve the request and meet applicable legal obligations; contact us about access, correction or deletion.

5. This website and external links

This website is hosted by Vercel. Vercel processes network requests, such as IP addresses and request information, to deliver and protect the site. These pages do not include analytics or advertising scripts, cookies or account forms. Email services process messages you choose to send.

Research links in the app open external websites. Their privacy practices apply when you visit them. Your practice history and calm ratings are not included in those links.

6. Sharing and changes

We do not sell personal information or share it for cross-context advertising. Website hosting and email providers process information needed to perform their services. Information may also be disclosed where required by law or necessary to address security incidents or protect legal rights. We will update the effective date if this policy changes.
