Effective Date: November 17, 2025
This Privacy Policy explains how EyeKeyboard (“we”, “our”, or “us”) handles personal information when you use the EyeKeyboard mobile application (the “App”). By using the App, you consent to the practices described here.
We may collect basic diagnostic information (such as crash logs, feature usage counts, and anonymized performance metrics) to improve the App. This data does not include any textual content you input.
The App uses Apple's TrueDepth API through ARKit framework to enable eye-controlled text input. This is the core functionality that allows users with motor disabilities to type using only their eye movements.
What Data We Collect:
What We Do NOT Collect:
How We Use This Data:
All facial data collected through the TrueDepth API is used exclusively for the following accessibility purposes:
Data Processing and Storage:
All TrueDepth data processing is ephemeral and happens in real-time on your device:
Third-Party Sharing:
We do NOT share any TrueDepth data with third parties. No facial data is transmitted to external servers, analytics services, advertising networks, or used for any purpose other than providing the eye-tracking functionality described above.
User Control:
You maintain complete control over camera access. You may revoke camera permission at any time through iOS Settings, which will immediately stop all TrueDepth data collection. The App cannot function without camera access, as eye tracking is the core feature.
Your typed or dictated text remains on your device unless you choose to export, copy, email, or otherwise share it. We do not transmit or store your input on our servers.
Configuration values (e.g., sensitivity sliders, voice gender, purchase status) are stored via Apple’s secure storage APIs (UserDefaults or Keychain). Biometric data, camera frames, and real-time eye-tracking signals never leave your device and are not persisted after each interaction. We implement reasonable safeguards to protect all stored settings, but no method can guarantee total security.
The App relies on Apple frameworks such as ARKit (including TrueDepth API access), AVFoundation, and StoreKit. The TrueDepth API is accessed exclusively through Apple's ARKit framework and all facial data processing occurs on-device. These frameworks may collect diagnostic data per Apple's own privacy policies, which are outside of our control. We do not share any TrueDepth data with third-party services, analytics providers, or advertising networks. In-app purchases are processed by Apple, and any payment information is managed solely by Apple.
The App is not directed to children under 13, and we do not knowingly collect personal data from children. If you believe a child has provided us with information, please contact us so we can delete it.
We retain only the minimal configuration data necessary to provide a consistent experience. You may reset onboarding, purchases, or sensitivity values at any time within the App, which clears the associated local storage.
Important: No facial or biometric data collected through the TrueDepth API is retained. All TrueDepth data (facial landmarks, gaze vectors, eye positions, blink states, depth information) is processed in real-time and immediately discarded. No camera frames, facial images, or biometric identifiers are stored on your device or transmitted to any servers.
If you access the App outside of your home country, you consent to the processing and storage of your information within that jurisdiction’s applicable laws.
We may update this Privacy Policy from time to time. Material changes will be posted within the App or on our website, and the “Effective Date” will be updated accordingly. Continued use of the App after changes take effect constitutes acceptance of the updated Policy.
