Nila public research demo: privacy note

Nila is an imaginary, non-commercial research demo. It is not a person, therapist, or source of professional advice. Only adults aged 18 or older may take part. You can stop at any time.

What is processed

• When you use speech recognition, your microphone audio is sent to a third-party cloud speech-recognition provider in India for transcription. Audio is used for that request and is not saved by this demo.

• Sound reflexes (such as laughter, crying, shouting, and bangs) run in your browser. The camera is optional; face features are processed in your browser. Camera frames and sound recordings are never uploaded by Nila or stored by this demo.

• Typed messages stay in the browser except that, if you consent to text logging, their text and Nila's derived reactions are included in your saved session.

• If the speech quota is exhausted, you can type instead. Chrome speech recognition is an optional fallback; if you choose it, Chrome sends audio to Google. The app asks for separate consent before switching.

What may be stored

Only when you opt in to text logging, the saved timeline contains transcript text, Nila's reactions, sound/face event labels, and derived timing and affect values. If you decline text logging, the timeline is not stored; you may still choose to save your five ratings and written feedback. A save is sent to the project's private Hugging Face dataset, readable only by the project owner. Audio and video are never part of a saved session.

The demo does not ask for your name. Avoid names and other identifying details in speech and feedback. A session ID is shown when the session ends; keep it if you later request deletion.

Retention and deletion

Session records will be deleted after the study and retained for no longer than six months. To ask for deletion, contact [study contact] and include the session ID shown at the end of your session.

Cost limits

Speech requests are limited to ten minutes per invite code (5 credits), three sessions per invite, fifteen minutes per session, 120 minutes per UTC day, and 50 credits for the whole trial. The service charges usage before forwarding each valid request to prevent concurrent requests exceeding the cap. The provider processes each request under its own terms; the project owner can name the provider on request.
