# LINGO Safety and Abuse-Prevention Notice

LINGO is a private beta AI phone-receptionist backend owned and operated by the Space owner. It is intended only for lawful business call handling and testing.

## Intended use

- Answer inbound calls routed by the owner's LiveKit project.
- Transcribe caller speech using the owner's Deepgram account.
- Generate short receptionist-style responses.
- Speak responses back to the caller using local text-to-speech.
- Collect messages and appointment requests.
- Escalate callers who request a human.

## Not intended / not allowed

This Space is not intended for, and should not be used for:

- spam calling or robocalling
- phishing, impersonation, fraud, or credential collection
- harassment, abusive automation, or unsolicited outreach
- malware hosting, payload delivery, scraping, or botnet behavior
- bypassing platform restrictions or abuse controls
- collecting sensitive personal information beyond ordinary call-back details

## Secrets and privacy

- API keys and tokens are stored only as Hugging Face Space Secrets.
- The repository does not hard-code secrets.
- Health and diagnostics endpoints report only secret presence/missing names, never values.
- Caller transcripts are not exposed through public health endpoints.

## Runtime behavior

- The app exposes only HTTP health/status/metrics/diagnostics endpoints and the LiveKit worker backend.
- The worker connects only to the configured LiveKit project using owner-provided secrets.
- The system is beta and is not advertised as production-ready until a real call test passes.

## Contact / review note

If this Space was automatically flagged, please review it as a private beta telephony backend and not as a public automation/spam tool. The code is intended for a single owner's receptionist workflow and contains no malware, phishing logic, or secret exfiltration behavior.
