Hi team, please reach Jane at [EMAIL_1] or call [PHONE_1].
Billing card on file is [CARD_1], SSN [SSN_1].
Prod box is [IP_1] and the API key is [SECRET_1].
Loop in [EMAIL_2] if anything breaks.

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.
