About Us
Privacy-First Time Tools for a Post-Cloud Web
We build professional time tools for people who cannot afford ambiguity.
XenTimer is part of the XEN Suite — a growing ecosystem of privacy-by-design web applications that run entirely inside your browser.
No uploads
No tracking
No accounts
No cloud
Your time data never leaves your device.
Not temporarily. Not anonymized. Never.
Why XenTimer Exists
Modern time tools are built for surveillance, not clarity.
Most "free" timers and productivity tools monetize by:
- tracking user behavior
- profiling work patterns
- syncing activity to cloud dashboards
- locking basic functionality behind accounts or subscriptions
For casual use, this may go unnoticed.
For professionals, freelancers, students, and privacy-conscious users, it is unacceptable.
Time is personal.
It reflects how you work, think, focus, and live.
XenTimer was created as a direct response to a web where even a simple timer reports back to someone else.
Our Philosophy: Practice as a Protocol (PaaP)
XenTimer follows a strict architectural principle called Practice as a Protocol (PaaP).
It means:
Software must work without trust
Zero-knowledge architecture by design
Privacy must be provable, not promised
Technical guarantees, not marketing claims
Compliance must be a property of the architecture
Not a checkbox, but inherent to the system
If a feature requires sending your time data to a server,
we don't build it.
How XenTimer Works (Technically)
All XenTimer tools run:
100% Client-Side
No server processing
In Your Browser
Local execution only
Web Standards
Modern APIs, no tricks
This enables:
- ✓Instant timers and countdowns
- ✓Offline-capable usage

- ✓GDPR compliance by design
Even we cannot see your timers — because there is no technical path for that to happen.

Who Is Behind XenTimer
XenTimer is created by Roland Kaloczi, an independent developer and system architect based in Austria.
His work focuses on:
- ▸Privacy-first software architecture
- ▸Local-first and zero-knowledge tooling
- ▸Post-SaaS web models
- ▸Ethical software without surveillance
The goal is not growth at any cost.
The goal is software integrity.
Our Commitment
✓We do not sell user data.
✓We do not track behavior.
✓We do not train AI on user activity.
✓We do not ask for trust — we remove the need for it.
XenTimer proves that even the simplest tools
can be built honestly.
The Bigger Picture
XenTimer is not just a timer.
It is part of a broader movement toward:
Local-first utilities
User sovereignty
Zero-knowledge web tools
A post-cloud internet
The future of productivity is not more data.
It is clearer boundaries.
