BreathHoldWork App – Privacy Policy

Last updated: May 2026

This Privacy Policy explains how the BreathHoldWork mobile application ("the App") handles information and user data.

1. Overview

The BreathHoldWork app is a practice instrument for breath-holding training. Foundation Mode is free to use. BHW Premium is an optional subscription that unlocks Advanced Practice features. The app collects only the minimum information required to operate, and only when you choose to subscribe.

2. Information We Collect

If you use Foundation Mode without subscribing, we do not collect any personal data. Your practice data remains on your device.

If you subscribe to BHW Premium, we collect:

• Subscription transaction records from Apple, used solely to validate your active subscription status
• An anonymous device-level identifier provided by Apple, used by RevenueCat (our subscription processor) to maintain your entitlement across reinstalls and devices
• Activation code redemptions, if you redeem a code provided through other channels

We do not collect:

• Your name, email address, phone number, or physical address
• Health data, biometric data, or any data from HealthKit
• Location, contacts, photos, or microphone audio
• The Apple Identifier for Advertisers (IDFA)
• Cross-app or cross-website tracking data
• Usage analytics tied to an individual user

3. On-Device Data

All practice data — sequences, session timing, preferences, training history — is stored locally on your device. This data is not uploaded to external servers, is not accessible by the developer, and can be removed by deleting the app.

4. Third-Party Services

If you subscribe to BHW Premium, your subscription is processed through:

• Apple, Inc. — handles all in-app purchases and payment data. Apple's privacy policy: https://www.apple.com/legal/privacy/
• RevenueCat, Inc. — manages subscription entitlements on our behalf. RevenueCat's privacy policy: https://www.revenuecat.com/privacy/

Foundation Mode users do not interact with any third-party services.

5. Data Retention

Subscription records are retained as long as your subscription is active and for a reasonable period after cancellation to comply with tax and accounting requirements. You can request deletion of your subscription records at any time.

6. Your Rights

You have the right to access, correct, delete, or export the personal information we hold about you. To exercise any of these rights, contact us at [email protected]. If you are in the European Economic Area, United Kingdom, or California, additional rights apply under GDPR / UK GDPR / CCPA.

7. Children's Privacy

The BreathHoldWork app is not directed to children under 13. We do not knowingly collect personal information from anyone, including minors.

8. Security

Subscription data is processed via Apple and RevenueCat, both of which use industry-standard encryption in transit and at rest. On-device data remains under your control on your own device.

9. Changes to This Policy

We may update this Privacy Policy. When we do, we will update the revision date above. Material changes will be communicated via the app.
