Breathfall collects nothing. Your heart data never leaves your devices.
None. Breathfall has no accounts, no analytics, no advertising, no tracking SDKs, and no servers. The App Store privacy label is “Data Not Collected”.
During a breathing session, Breathfall reads your heart rate from Apple Watch through Apple HealthKit — only while a session is running, and only after you grant permission. Session results (heart-rate curve, summary numbers, coherence score) are stored locally on your devices and are excluded from device backups. You can delete them at any time by deleting the app.
With your permission, Breathfall saves each session to Apple Health as a Mind & Body workout and mindful minutes. That data lives in Apple Health under Apple's privacy protections and is never read back for any purpose other than what you see in the app. HealthKit data is never used for advertising or shared with anyone.
The optional one-time purchase is processed entirely by Apple. We receive no personal information about you.
You can export your session summaries as a JSON file from Settings. The export happens on your device and goes only where you choose to send it.
Breathfall is for relaxation and general wellness. It does not diagnose, treat, or prevent any disease or medical condition.
