Dynaface is not a medical device

Dynaface is a research tool. It is not a registered medical device and is not intended to diagnose, treat, cure, prevent, or monitor any disease or medical condition; it provides informational facial symmetry measurements only.

AI-based measurements may contain errors, and can be affected by image quality, lighting, pose, facial expression, camera angle, and landmark detection accuracy. Always independently verify results before relying on them for clinical, research, or decision-making purposes.

Privacy

Dynaface collects no data and no personal information. It is not designed to transmit image or video data to any external server, cloud platform, or third-party data center; all analysis runs locally. The only network access the application initiates is opening your web browser to view the online manual. All output — annotated images, CSV, and Excel exports — is written to locations on your own file system that you choose.

Research Use

Institutional requirements for clinical research — IRB approval, HIPAA considerations, and similar — are the responsibility of the researcher's institution and are not addressed by the Dynaface license.

License

Dynaface is released under the Apache License 2.0. Researchers should review the license terms directly, as they govern permitted uses, redistribution, and disclaimers of warranty. No additional proprietary licensing is imposed by the Dynaface project itself.

Dynaface builds on three neural networks with their own licenses — BlazeFace (Apache-2.0), SPIGA (BSD-3-Clause), and U²-Net (Apache-2.0). If you use Dynaface in academic work, please cite their original authors alongside Dynaface; the references are in the project README.
