Try it, no account needed

See exactly what leaves, and prove it later.

Put something sensitive below and press Govern. Card numbers, emails, phone numbers and IP addresses come back as stand-ins of the same shape — still valid emails, still Luhn-valid cards — so whatever consumes the output keeps running; other classes, IBANs and national identifiers among them, come back as labelled placeholders. Here the substitution is one-way, so the receipt says redact: nothing is kept and nothing can be restored. On an account that keeps a token vault the same step is reversible and the receipt says tokenize. Credentials are refused outright.
