BlokDuck is an on-device document-redaction tool built by Quantafin Lab LLC. Our software finds sensitive values in a document and writes a protected copy beside it, entirely on your own computer — the document is never uploaded and never sent to us.
BlokDuck is a trading name of Quantafin Lab LLC:

BlokDuck reads documents in common business and clinical formats, identifies sensitive values with a deterministic rule set, and writes a shareable protected copy plus a private key that can restore the original values. Detection is rule-based and explainable — there is no large language model in the pipeline and no content leaves the device. The product runs as a local server, a command-line tool, or a container you control.
Your documents are processed locally and we never receive them. We are the controller of the limited personal information needed to run the Website, issue licence keys, take payment and answer support requests, as described in our Privacy Policy. When you ask us to process a document for a service on your instructions, we act as a processor under our Data Processing Addendum.
We use one contact address, [email protected], with a subject prefix so your message reaches the right place. We aim to reply within three business days.
