Haea

Q: Does Haea sync to the cloud?

No. All health data stays on your device. Haea uses no cloud sync, no third-party SDKs, and no analytics services. Your data never leaves your iPhone.

Q: Is Haea HIPAA-compliant?

Haea is designed with a privacy-first architecture: all data is stored on-device with no cloud transmission or third-party access. While Haea is a consumer app and not a covered entity under HIPAA, its design exceeds typical health app privacy standards.

Your complete health picture, on your phone. Haea integrates sleep, nutrition, activity, and biometrics to surface patterns you'd otherwise miss — through advanced ML, entirely on-device.

Intelligence that goes deeper

Energy Balance & TDEE

Calculate your true daily energy expenditure from actual weight and calorie data. Auto-detects eating patterns and surfaces your real caloric balance over rolling windows.

Circadian Rhythm Intelligence

Tracks your biological circadian phase. Identifies your optimal windows for energy, focus, and sleep — then shows the transition between active and wind-down phases.

Running Analytics

FIT file export, colored route maps with pace visualization, mean max power curves, and polarized training zone breakdown for serious runners.

Advanced ML models

Dose-response curves, Granger causality analysis, adaptation tracking, and Kalman-filtered recovery state estimation. What actually causes what in your health data.

Biological metrics

Biological age estimation, VO₂ max tracking, DFA-α1 heart rate variability analysis, and circadian age (CosinorAge). Metrics that move, not just snapshots.

Private by design

No cloud sync. No third-party SDKs. No ads. All analytics run on-device using GRDB.sqlite local storage. Your health data never leaves your phone.
