Privacy Policy

Blink · Effective 12 July 2026

The short version

Blink does not collect, store or transmit any personal data. Everything the app does happens on your device.

Camera and face data

Blink uses the front TrueDepth camera, via Apple's ARKit, to measure blink rate, gaze direction and gaze distance during desk sessions you start. This processing happens entirely on your iPhone in real time:

• No photos or video are ever recorded or saved.
• No face data, gaze data or camera imagery ever leaves your device.
• The camera is off outside of sessions and breaks you initiate.
• Face data is used solely to verify eye breaks and drive eye-exercise games; it is never used to identify you.

What we store

Your session history, break streaks, settings and calibration are stored locally on your device (and in your device backups). We have no servers and no account system, so we cannot see any of it.

Purchases

Subscriptions are processed by Apple through the App Store. We never see your payment details. See Apple's privacy policy for how Apple handles purchase data.

Analytics and tracking

Blink contains no third-party analytics, no advertising SDKs and no trackers.

Children

Blink is not directed at children under 13 and collects no data from anyone.

Changes

If this policy changes, the updated version will be posted at this address with a new effective date.
