Privacy Policy
Effective Date: April 7, 2026
Breon ("the App") is developed by Kevin Liu ("we", "us", "our"). We are committed to protecting your privacy. This Privacy Policy explains how we handle information when you use Breon.
Breon does not collect, store, process, or transmit any personal data whatsoever. We have no servers, no databases, and no analytics infrastructure.
The App stores your preferences (interface brightness, breath counter setting, guided mode preference, breathing calibration data, and session state) locally on your device using iOS UserDefaults. This data never leaves your device and is not accessible to us or any third party.
Breon contains no analytics frameworks, no tracking pixels, no advertising SDKs, and no third-party code that collects information. We do not use Apple's App Analytics to collect device-level data.
Breon does not integrate with any third-party services, APIs, or SDKs. The App functions entirely offline and requires no internet connection.
Breon does not require or support user accounts. There is no sign-up, no login, and no user profile of any kind.
Breon does not knowingly collect any information from anyone, including children under the age of 13. Since the App collects no data, it is compliant with COPPA and similar regulations.
We do not share, sell, rent, or trade any information with third parties because we do not collect any information.
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated effective date. Continued use of the App after changes constitutes acceptance of the updated policy.
