## What is Presence Auth?

Presence is an iOS-first verifier app for proving live human presence to connected services while keeping raw health data on-device.

Use Presence to:
- open a verification request from a connected service
- connect with a request link or QR code
- review and manage connected services
- complete verification on this device
- receive accepted proof results from the service
- check whether this device is Pass ready based on the best qualifying day in the last 72 hours

Presence is designed so raw health data stays on-device. Connected services receive proof output and verification results, not your raw HealthKit history.
