Overview

Breath Holds is a personal breathing and breath-hold training app. This policy explains what data the app accesses and how it's used.

Health Data

With your permission, Breath Holds reads and writes data through Apple HealthKit — including heart rate and workout session data — to power live heart-rate feedback during sessions.

This data never reaches Breath Holds or its developer. The app has no server and no backend. All HealthKit data is requested, processed, and stored entirely on your own device, within Apple's HealthKit framework — the same private, on-device system used by Apple's own Health app. At no point does this data leave your device, get transmitted to the developer, or become accessible to anyone but you.

As a result, there is no health data for Breath Holds to sell, share, use for advertising, or disclose to any third party — the app is simply never in possession of it.

Data Storage

Session history and progress data, including heart rate readings recorded during a session, are stored locally on your device. Breath Holds does not operate a server and does not transmit your personal data to Breath Holds or any third party.

Apple Watch

If you use the Apple Watch companion app, heart rate data is transmitted directly between your iPhone and Apple Watch to enable live features during a session. This data is not transmitted anywhere else.

Children

Breath Holds is not directed at children and does not knowingly collect data from children.
