Built for teams that have to say no by default.

Files stay in the browser

Our software opens and processes files client-side. There is no upload step, so customer data never crosses the network to reach us.

Nothing stored on our side

We have no server-side copies of your files to secure, retain, or breach. What we never receive, we can never lose.

Documented for review

We explain our architecture plainly so your security and vendor-risk teams can verify what we claim. Questions go to our inbox.

Evaluating us as a vendor?

If you're reviewing IrinHawk for procurement or vendor risk, we'll answer architecture and diligence questions directly.
