What was found
How this works. Detection is deterministic and pattern-based, tuned for high precision
(card numbers are Luhn-checked to cut false positives). It runs entirely in your browser —
this page makes no network calls. It is a strong helper, not a guarantee: names,
physical addresses and free-form personal context are not auto-detected (reliable detection
of those needs a model and would defeat the local-only promise). Always read the output
before you share it.
