About Us

Privacy-First Software for a Post-Cloud World

We build professional web tools for people who cannot afford data leaks.

HexPdf is part of the XEN Suite — a growing ecosystem of privacy-by-design applications that run entirely inside your browser.

No uploads
No tracking
No accounts
No cloud

Your data never leaves your device.

Not temporarily. Not encrypted. Never.

Why HexPdf Exists

The modern web is broken.

Most "free" online tools monetize by:

  • ▸ uploading your documents to servers,
  • ▸ scanning them with AI,
  • ▸ storing copies,
  • ▸ and turning sensitive information into data exhaust.

For individuals this is risky.
For professionals, it is unacceptable.

HexPdf was created as a direct response to this problem.

Our Philosophy: Practice as a Protocol (PaaP)

We follow a strict architectural principle called Practice as a Protocol (PaaP).

It means:

  • Software must work without trust.

  • Privacy must be provable, not promised.

  • Compliance must be a property of the architecture, not a checkbox.

If a feature requires sending your data to a server, we don't build it.

How It Works (Technically)

All HexPdf tools run:

  • 100% client-side
  • inside your browser
  • using modern technologies like WebAssembly

This enables:

  • ✓ instant processing
  • ✓ offline capability
  • ✓ zero data exposure
  • ✓ full GDPR compliance by design

Even we cannot see your files — because there is no technical path for that to happen.

Who Is Behind It

HexPdf is created by Roland Kaloczi, an independent developer and system architect based in Austria.

His work focuses on:

  • → privacy-first software architecture
  • → zero-knowledge tooling
  • → post-SaaS web models
  • → ethical monetization without surveillance

The goal is not scale at any cost —
the goal is software integrity.

Our Commitment

We do not sell user data.

We do not train AI on user content.

We do not track behavior.

We do not ask for trust — we remove the need for it.

HexPdf proves that professional, high-performance web software can exist without surveillance.

The Bigger Picture

HexPdf is not just a PDF tool.

It is part of a broader movement toward:

local-first software

user sovereignty

zero-knowledge infrastructure

a post-cloud internet

The future of the web is not more data.

It is better architecture.
