Privacy-First Health Tracking

In an era of health data breaches, on-device computing is the gold standard for privacy-conscious users.

What is on-device health tracking?

On-device means AI analysis and health computations happen locally on your iPhone — not on cloud servers. Your data stays on your device.

Why local-first?

  • No third-party server storage
  • Works offline
  • You control all sharing permissions
  • Web tools compute locally in your browser too

Treelet Health's approach

Treelet Health uses on-device AI, syncs Apple Health without external storage, and all web calculators run locally in your browser.
