Redaction with a receipt.
Drop a document. cloak-redact finds every name, email, phone number and ID, redacts them on your device, and hands you the clean file plus a signed receipt that proves nothing ever left this machine.
Drop your document
or choose a file — it opens in this tab only
Open your network panel and watch. It stays silent — the file is never transmitted.
Every redaction SaaS asks you to upload the exact file you're trying to protect.
That is the self-refuting pitch of the whole category. cloak-redact never receives your file — extraction, detection and redaction all run in this browser tab — and it issues a cryptographic receipt so you can prove it to a regulator, a client or a court.

Your document opens in this browser tab. It is never uploaded — extraction runs on-device.
Review

Download the redacted file and a signed receipt that verifies offline — proof nothing left your device.
