Calmeye AI: Eye Care & Relax (“Calmeye”, “the app”) is developed by Vadim Semenko at ZeroSix Studio (“we”, “us”). Calmeye is built so that the least possible amount of information ever leaves your iPhone. There is no account, no login and no analytics profile tied to you.

What stays on your device

Your sessions, streaks, schedule, Eye Age history, rest plan and preferences are stored locally on your device. Camera frames used by the fatigue check-in are processed as they arrive through Apple’s on-device frameworks and are never written to disk, uploaded or shared.

Camera and face data — the eye-fatigue scan

The 20-second check-in is optional, and the rest of the app works without it. While it runs, Apple’s on-device Vision framework detects facial-landmark points around your eyes (eye contours and pupils) in each live camera frame and returns their coordinates to the app in memory. From those coordinates the app derives only numeric comfort metrics — how open your eyes are, blink rate, squint and gaze steadiness.

The app does not build a face model, faceprint or face-geometry template, does not use the TrueDepth face mesh or ARKit face tracking, and does not perform face recognition or identification. No photos or video are captured.

How it is used:the numeric metrics are combined on your device into a single wellness comfort score (0–100), shown to you as your Eye Age. That is the only use of the face data.

Sharing: none. Camera frames and facial-landmark data are processed live on your device and are never transmitted to us, to the AI Eye Coach, or to any third party. Face data never leaves your device.

Retention:camera frames and facial-landmark points are held only transiently in memory during the scan and are discarded immediately after each frame is processed — they are never photographed, written to storage or uploaded. Only the resulting numeric comfort score is saved locally on your device, and you can delete it at any time via Settings → Delete all data.

AI Eye Coach — a cloud AI service

The AI Eye Coach is optional and asks for your permission before its first cloud request. The consent screen states what is sent and to whom, and the message field stays hidden until you allow it; at the network layer no request is made without consent.

When you use it, the app sends only the text you type, plus a per-install device identifier used for rate limiting, to our gateway on Cloudflare, which forwards it to the model provider OpenRouterto generate a reply. No name, no email address, no photos, no camera frames, no fatigue-scan data. You can revoke the permission at any time in Settings → AI Coach → Cloud replies, and the rest of the app keeps working.

What else leaves your device

• Anonymous usage and crash diagnostics through Google Firebase (Analytics and Crashlytics) — product interaction, device and installation identifiers, and crash data. Not linked to your identity and not used to track you across apps or websites.
• Purchase state through RevenueCat and Apple, so the app knows whether a subscription is active. Payment details are handled by Apple; we never see them.

Your location is never sent anywhere. Sunset mode works out sunrise and sunset on the device itself, and the coordinates stay there.

Children

Calmeye is not directed at children under 13 and we do not knowingly collect information from them.

Your choices

You can revoke the coach’s cloud permission at any time in Settings, and the app keeps working. Settings → Delete all data clears your local history, and deleting Calmeye removes everything it stored on the device.
