HelloFace SDK brings face processing to the device, giving developers native integration options for Android, iOS, HarmonyOS, Windows, and Linux.</p> <h2> What the SDK provides </h2> <ul> <li>Face detection and feature extraction.</li> <li>Guided face capture.</li> <li>Action-based and passive liveness detection.</li> <li>1:1 face verification.</li> <li>1:N and M:N face search with local database management.</li> </ul> <p>The SDK processes face images and recognition features locally, without sending them to a remote face-recognition service.</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2F9av4ns08g7cs7ffn263f.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2F9av4ns08g7cs7ffn263f.png" alt="HelloFace product overview and application scenarios" width="800" height="533"></a></p> <p><em>This illustration comes from the project's public README. The displayed match value is illustrative, not a recognition-accuracy benchmark or a hardware test result.</em></p> <h2> The Android demo is now on Google Play </h2> <p><strong>The Android demo is now available on Google Play after completing Google Play's publication review.</strong> That review process includes checks against applicable app safety and privacy policies. <a href="https://google.play/intl/ALL_uk/howplayworks/" rel="noopener noreferrer">Learn about Google Play's review process</a>.</p> <p><strong><a href="https://play.google.com/store/apps/details?id=com.hiface.sdk.debug" rel="noopener noreferrer">Download the Android demo on Google Play</a></strong></p> <p>The SDK's on-device face processing and the Android app's overall data practices should be considered separately. The <a href="https://play.google.com/store/apps/datasafety?id=com.hiface.sdk.debug" rel="noopener noreferrer">Google Play Data safety section</a> provides the app's current developer disclosures.</p> <h2> Linux and embedded devices </h2> <p>For Linux developers, HelloFace provides x86_64 and ARM64 binaries, a public C ABI, command-line examples, and a customizable desktop demo. The SDK can be integrated into applications without a desktop environment; the supplied graphical demo requires X11 or XWayland.</p> <p>For embedded Linux projects, the demo provides display rotation, touch-friendly controls, and RGB/IR paired-search integration for supported hardware. Camera configuration, calibration, and performance should be validated on the target device.</p> <h2> Native mobile integration </h2> <p>HarmonyOS developers can integrate through ArkTS interfaces and a native HAR package. Android and iOS have their own native integration guides and demos. Public demo integration code and platform guides are available on GitHub; the SDK core is distributed as binaries.</p> <p>The public 0.8.11 release is Beta and intended for testing. The current models do not support children under 12 and must not be used in financial scenarios. Face-search deployments require clear camera images; outdoor deployments require camera wide dynamic range above 100 dB. Windows/Linux desktop and camera workflows still require validation with real cameras; mobile apps require their own application signing.</p> <p>Explore the examples, try the Android demo, and share your integration feedback:</p> <ul> <li> <strong>Website:</strong> <a href="https://www.helloface.dev/" rel="noopener noreferrer">helloface.dev</a> </li> <li> <strong>Demo code and documentation:</strong> <a href="https://github.com/FaceSDKPro/HelloFace" rel="noopener noreferrer">FaceSDKPro/HelloFace</a> </li> <li> <strong>Feedback:</strong> <a href="https://github.com/FaceSDKPro/HelloFace/issues" rel="noopener noreferrer">GitHub Issues</a> </li> <li> <strong>SDK integration support:</strong> <a href="mailto:FaceAISDK.Service@gmail.com">FaceAISDK.Service@gmail.com</a> </li> </ul> showdev android linux machinelearning
