Privacy & Refund Policy

Eyeline uses your camera only to work out where you're looking. Camera frames are processed on your computer, kept in memory for a moment, and thrown away. Nothing is recorded, saved or sent anywhere.

• Eyeline reads camera frames to estimate which way your head and eyes point (Apple Vision on macOS, MediaPipe on Windows and Linux). This runs entirely on your computer.
• Frames are never written to disk and never leave your computer.
• The camera stops whenever you pause Eyeline, and when your computer locks or its display sleeps.

The “Try it here” demo only starts when you click it and your browser asks for camera permission. It runs MediaPipe in your browser: video stays on your device and is never uploaded. Your browser downloads the face-tracking model and its runtime from Google and jsDelivr, as it would any other file. The camera turns off when you press Stop, press Esc or leave the page.

• Your settings.
• Calibration data: numbers describing head and eye angles paired with points on your screens. Not images.

Both stay on your computer. Deleting the app's settings removes them.

To avoid moving focus while you type or use the mouse, Eyeline notes when you last pressed a key or moved the mouse. It doesn't record which keys you press or what you type. Clicks are used, with the gaze reading at that moment, to improve calibration; that data stays on your computer.

Eyeline makes no network requests of its own today. When licensing and update checks are added, it will contact our servers only to validate your license key and to check for a new version — never to send camera, calibration or usage data. This page will be updated before that ships.

There is no account to create. Eyeline contains no analytics or tracking. This website sets no cookies and uses no analytics.

Purchases are handled by our payment provider, which receives what it needs to process your payment and handle tax. We receive your email address and order details to send your license key and help with support.

Try Eyeline free for 7 days before you buy. If it isn't right for you, email us within 14 days of your purchase for a full refund — no questions asked. Refunds go back to your original payment method, and the license key is deactivated.
