A note from the studio
“I practise pranayama and wanted a tool that respected it — correct ratios, no upsells, no streak guilt, and no data leaving the phone. BreathStack has no analytics and no network calls at all. It just helps you breathe.”
Questions
The honest answers.
What data does BreathStack collect?
None. It has no analytics, no crash reporting, and makes no network calls. Everything stays on your device.
Is it really a one-time purchase?
Yes — $19 once, forever. No subscription, no ads.
How does the Apple Health integration work?
With your permission it reads your HRV sample just before and after a session to show an honest delta, and writes mindful minutes. It reads and writes only what you allow.
Is this medical advice?
No. BreathStack is a wellness tool. Some techniques are intense — stop if you feel unwell, and consult a doctor if you have a heart or respiratory condition.
