How to use this tool

Paste a sample document, choose categories, and replace pattern matches with [REDACTED] markers. This is a convenience tool using regular expressions, not a complete personal-data discovery or compliance system. Inspect the output: some secrets will be missed and ordinary numbers might be hidden.

Questions and answers

Will it remove names and credit-card numbers?

No. Only selected email, phone-like and IPv4 patterns are considered.

Can I use it to prepare legal or confidential documents?

Do not rely on it alone. Always manually inspect and use the disclosure procedures appropriate to your data.
