Built with a real club, not in a boardroom
I watched a club drown in Excel and Messenger. So I built KlubOS.
Today it runs UKJ Yuko, a Polish judo club with 767 athletes. Fees bill themselves, results live in one place, and every parent has an app with their child's attendance. Grown on a club's daily reality, not a pitch deck.
Not a mockup. It runs in production. Numbers below are live.

// before KlubOS, a club juggled all of this:
Six places where things got lost. Now one login, and peace of mind.
FEATURES
Everything that eats a coach's evenings. Now the system does it.
No feature was invented on a whiteboard. Each one exists because something at a real club kept breaking without it.
Club website that runs itself
Your own domain, news, calendar, galleries and athlete profiles. Results and medals publish themselves. No webmaster invoices.
Parent app (PWA)
Attendance with streaks, fees and online payment, schedules, medals, two-way chat with the club and push notifications, installed straight to the home screen.
Fees that collect themselves
Automatic monthly billing, online payments, smart dunning (email → SMS), bank statement import with payer memory, and e-invoices.
Attendance & churn radar
QR check-in at the door or one-tap roll call. Falling attendance triggers an early warning before a family quietly leaves.
Results = marketing
Enter a result once: your website updates, a branded graphic is generated, and a Facebook post is one tap away. Parents share their kids, and recruitment follows.
Competition readiness
One glance shows who can compete on match day: medicals, licence and insurance validated against the event date, with one-click parent reminders.
Camps, end to end
Registrations and instalments, statutory qualification cards, a live camp diary for parents, moderated greetings on the venue TV and a private live stream link.
Board-ready reporting
One-click PDF: growth, finances, collection rate, medals, attendance and demographics, ready for your board, your city hall or a grant application.
Child safety & GDPR built in
Consent management, per-club data isolation, EU hosting, safeguarding module and pickup permissions as a standard, not an add-on.

Frequently asked
Is KlubOS available outside Poland?+
KlubOS is built for Polish sports clubs first (parent payments via Przelewy24, Polish e-invoicing, Polish legal templates). If you run a club elsewhere and are interested, get in touch. The core platform is country-agnostic and we are planning the rollout roadmap.
What does it cost?+
All features are included: you pay for club size, not for a feature package. From 99 PLN/month (~€25) for up to 40 athletes, 249 PLN up to 120, and 449 PLN for a larger club with no athlete limit. Yearly billing gives you two months free. Even the smallest club gets online payments, the parent app and everything else.
Who is behind KlubOS?+
A software engineer who watched a real judo club drown in spreadsheets. Every feature was battle-tested with UKJ Yuko (a Polish club with 767 athletes and 13,000+ recorded fights) before it shipped.
How do you handle children's data?+
EU data residency, strict per-club isolation (row-level security), parental consent controls for photos and public profiles, EXIF/GPS stripping on uploads, and a safeguarding module aligned with Polish child-protection law.
