A closer look

What each mode changes.

Each item becomes a believable stand-in. A name turns into another name, an address into a plausible address. The text stays natural, so an AI still reads a document that makes sense. It is reversible. The mapping back to your real data lives in the AES-256-GCM vault, unlocked with your passphrase, on your machine.

The GDPR note

Pseudonymized data is still personal data under the GDPR, because it is reversible. It lowers your risk without making the data anonymous. Redaction removes the data, so there is nothing left to expose.

A reminder on limits

Automatic detection helps. It does not replace a read-through. On a sensitive document, check the result before you share it. The tool helps. It does not decide for you.
