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 unstructured 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.
What it removes from your text
Private keys, JWT tokens, API keys and tokens, credentials inside URLs, secret assignments (like PASSWORD=…), emails, card numbers (checked with Luhn to avoid false positives), IP addresses and phone numbers.
What it doesn't catch
Names, physical addresses and unstructured personal context. Detecting those well needs a model and would break the promise of running locally, so always read the output before you share it.
