The iOS app

Use of the iOS app is governed by Apple’s Standard EULA for Apps. By installing HRV Breathe through the App Store, you agree to those terms.

Subscriptions

HRV Breathe Pro subscriptions auto-renew at the end of each billing period unless canceled at least 24 hours before the period ends. Manage and cancel subscriptions in your iOS App Store account settings. Free trials convert to paid plans unless canceled before the trial expires.

Lifetime purchases are one-time, non-recurring purchases that unlock Pro features for as long as the app exists. Lifetime is family-shareable through Apple Family Sharing.

Refunds

All refunds are handled by Apple. We have no ability to issue refunds directly. Request a refund at reportaproblem.apple.com.

Not medical advice

HRV Breathe is a wellness tool, not a medical device. It does not diagnose, treat, cure, or prevent any disease. The HRV readings it surfaces are sourced from Apple Health and may contain measurement error from your wearable device. The breathing protocols it teaches are well-studied but should not replace professional advice for any medical condition.

If you have a heart condition, are pregnant, have a history of panic or fainting at hyperventilation, or are under treatment for any serious mental or physical illness, talk to your clinician before starting a new breathing practice.
