Detection runs entirely in your browser with pattern matching (cards are Luhn-checked to cut false positives), nothing you paste is uploaded, and there's no API. Numbered keeps each value distinct (the same email always becomes [EMAIL_1]) so an LLM can still follow the thread without ever seeing the real data. Always eyeball the result before sharing, pattern matching can miss unusual formats.
