FAQ

BlokDuck is highly functional, but you may still encounter small glitches. Please tell us about any glitches you find so we can fix them. For each new glitch you report, we'll reward you with a free license. A description of what happened and the steps to reproduce it help us investigate; please don't send private documents.

No. Blokduck runs entirely on your computer and never connects to the internet. Nothing you drop in the Blok folder goes online — not to us, not to anyone. You can turn your Wi-Fi off and it works exactly the same.

No. There is no account, no sign-in and no telemetry, so there is nothing for us to see and nothing for us to store. We do not know what you protect or how often you use it.

No. Your original stays exactly as it was. A protected copy appears beside it, clearly named, so you always know which one is safe to send.

Wherever you choose during install. The default is a folder in your Home directory, alongside the Blok folder itself. Nothing is written anywhere else.

Names, account and ID numbers, contact details, addresses, health information and financial figures. You review every protected copy before sharing, so you always have the final say on what stays hidden.

Yes — blokking is what we call it. If you work in legal, healthcare, lending or compliance and need the technical detail, request a demo and we will walk you through it.

Yes. Every protected copy opens for review before you send it, and you can add or remove a blok on any field. Teams can also define custom rules per document type, so a lease and a pay stub get treated differently.

PDFs and common image formats. If you have a format that matters to your workflow and it isn't supported yet, tell us — the roadmap is shaped by what people actually send.

Seconds, for a typical few-page document. Everything runs on your own machine, so speed depends on your computer rather than on a queue somewhere.

macOS on Apple Silicon and Intel, Windows 64-bit, and Linux x86_64. All four are on the download section of the homepage.

Four quick choices: whether you want the CLI, the browser app or both; a use-case profile that sets the default detection rules (healthcare, finance, legal and so on); where protected files should be written; and whether to add a desktop shortcut and menu-bar icon.

No. There is nothing to sign up for and nothing to log in to. Download it, install it, drop in a file.

Drop anything you plan to share into the Blok folder. A protected copy appears beside it within seconds. Attach from that folder and whatever you send is already protected.

Yes. The same engine deploys inside your infrastructure, with no outbound connection required. This is the usual setup for firms handling client files under a confidentiality obligation.

Yes — for teams building it into their own document pipeline, with an audit log of every blok. Request a demo and we will go through the integration.

Yes. Custom blok rules, defined per document type, so your lease template and your medical intake form each get the treatment they need.
