Privacy-First Data Toolsfor a Post-Cloud Web
We build data tools for people who cannot afford compromise.
HexDataTools is part of the XEN Suite — a growing ecosystem of privacy-by-design web applications that run entirely inside your browser.
Your data never leaves your device.
Not temporarily. Not anonymized. Never.
Don't trust our words — verify it yourself.
Live network monitoring. Exportable proof. Zero ambiguity.
Why HexDataTools Exists
Modern data tools are built around centralized control.
Most "free" online converters and data tools monetize by:
- collecting behavioral data
- uploading sensitive files to servers
- storing content or metadata in cloud systems
- locking essential features behind accounts or subscriptions
For casual users, this may seem acceptable.
For professionals, developers, and privacy-conscious users, it is not.
Your data is intellectual property. It should never become analytics signals, training data, or monetization assets.
HexDataTools was created as a direct response to a web where even basic data tools require blind trust.
Our Philosophy: Practice as a Protocol (PaaP)
HexDataTools follows a strict architectural principle called Practice as a Protocol (PaaP).
Software must work without trust
No blind faith required in service providers
Privacy must be provable, not promised
Open DevTools and verify: zero network requests
Compliance must be architectural
GDPR/DSGVO compliance is a property of the design, not a checkbox
If a feature requires sending your data to a server, we don't build it.
How HexDataTools Works (Technically)
All HexDataTools features run:
100% client-side
In your browser
Offline capable
This enables:
- instant data conversion and transformation
- local processing with modern Web APIs
- zero data exposure to third parties
- GDPR and CCPA compliance by design
Even we cannot access your data — because there is no technical path for that to happen.
Built for Data — Not Surveillance
Built For
- data conversion and transformation
- API testing and development
- schema validation and generation
- privacy-critical environments
- professional workflows
Not Built For
- data collection and profiling
- user tracking and analytics
- telemetry-driven features
- cloud storage or sync
- account-based monetization
HexDataTools gives you tools — not dependency.
No Accounts. No Tracking. No Trade-Offs.
Data tools should not know who you are.
Who Is Behind HexDataTools
HexDataTools is created by Roland Kaloczi, an independent developer and system architect based in Austria.
His work focuses on:
The goal is not mass adoption at any cost.
The goal is verifiable privacy.
Our Commitment
We do not store your files.
We do not log activity.
We do not analyze behavior.
We do not train AI on user input.
We do not ask for trust — we remove the need for it.
HexDataTools proves that data tools do not need servers to be powerful.
The Bigger Picture
HexDataTools is not a product. It is a position.
It stands for:
The future of data tools is not more dashboards.
It is fewer places where data can leak.
