This Privacy Policy describes how Unmask Lab ("the App", "we", "us", or "our") handles information when you use our photo capture and facial feature detection application.
Key Point: Photo capture, storage, and feature detection happen on your device. Photos you take are stored locally in the app's private storage unless you choose to export them to Photos. The App also displays ads (Google AdMob) and uses crash/diagnostic reporting (Sentry).
To provide the App's functionality, we request access to the following device features:
This section describes how Unmask Lab handles face data, in compliance with Apple's guidelines on sensitive user information.
Unmask Lab uses Apple's on-device semantic segmentation APIs (AVSemanticSegmentationMatte) and OpenCV image processing to detect and extract facial feature regions from photos you capture within the app. The facial features processed include:
The app generates segmentation mask images that highlight these facial regions. No biometric identifiers, face geometry, or facial recognition data are collected or generated. The app does not identify individuals or create face prints.
Face data is used solely for the following purpose:
The app is designed as a utility for users who want to create training datasets or visual outputs. The app does not perform facial recognition, identity verification, emotion detection, or any form of user profiling.
We do not share face data with any third parties. All face data processing occurs entirely on your device. The original photos and generated segmentation images are never uploaded to our servers or transmitted to any external service. Third-party services used by the app (AdMob for ads, Sentry for crash reporting) do not receive or have access to your photos or face data.
All photos and generated face data images are stored exclusively in the app's private sandboxed storage on your device. This storage is:
Face data (photos and segmentation images) is retained in the app's local storage until:
We do not retain any copies of your face data on external servers because no data is ever transmitted off your device.

All photos and extracted facial feature images are saved within the app's private sandboxed storage on your device. This means:
We do not sell your personal information. We do not share your in-app photos with third parties unless you choose to share/export them using iOS features (e.g., Share Sheet or saving to Photos).
