Data Minimization

How Circadify minimizes data collection and processing.

Data minimization is a core privacy principle at Circadify. We collect and process only the minimum data required to deliver a result — and we don't keep any of it.

Principles

  • Collect less — The SDK accesses the camera only for the duration of a single scan. No persistent recording occurs.
  • Process locally first — The SDK performs camera capture and quality checks on the device. Raw video and raw camera frames never leave the user's device.
  • Transmit only what's needed — Only an SDK-prepared measurement payload is uploaded for processing. It is not raw video.
  • Don't keep it — The measurement payload is processed and discarded. Vital sign results are returned to your application and are not stored on our side by default. The only state we persist from a scan is a usage record for billing and quota.

What We Don't Collect

Circadify never collects, transmits, or stores:

  • Raw video or camera frames — The SDK processes video locally and never uploads it.
  • Vital sign results — Results are returned to your application in the API response and are not stored on our side.
  • The measurement payload — Processed and discarded after processing. Not retained.
  • Persistent device identifiers — No device fingerprinting or cross-site tracking identifiers are collected.
  • Precise location data — No GPS, IP-based geolocation, or fine-grained location data is collected.
  • Unrelated sensor data — Only the device camera is accessed during a scan. No microphone, accelerometer, or other sensor data is collected.
  • Biometric templates — The uploaded measurement payload is not a biometric template and is not retained after processing.

Verification

Enterprise customers can request audit reports to verify our data-minimization practices.
