An independent software and technology studio.
Run by one developer in Antwerp, Belgium. Three things come out of it: software you host and own, BLE Radar and the sensing data behind it, and custom software and security work done to order.

Pillar 2 · Technology
BLE Radar
A phone powered sensing network, and the data it produces.
BLE Radar is an Android app that turns an ordinary phone into a field instrument. It measures real signals around you: Bluetooth, Wi-Fi, cellular, Wi-Fi spectrum, cellular spectrum, GNSS sky view, magnetic anomaly, air pressure, night light and sound.
Readings are aggregated into map hexagons before publication, so the public map contains area-level statistics rather than individual devices, routes or people. The project is early. Every number on the map is a real measurement, not a projection.
Eligible discoveries fund verified environmental action through 1ClickImpact: trees, ocean cleanup, carbon capture, clean water and animal support. Never tokens, never points, never cash.
What it never collects
No device identity, no person counts, no routes, no raw audio. Aggregate area statistics only, which is what makes the data safe to publish and to share with researchers.
How the privacy model works
Products · Sellers
Built something? Sell it here.
SevinHub takes outside products too. One-time pricing, lifetime ownership for the buyer, never subscriptions. Every listing is reviewed by hand before it goes live, which is why the catalogue stays small.
A flat fee, not a cut that grows
You set your own price. SevinHub charges one flat fee per sale for external sellers, so a more expensive product does not cost you more to sell.
Reviewed before it goes live
Every product is checked by hand. That is slower for you, and it is the reason buyers trust what is listed here.
Buyers who came looking
The audience here is specifically after self-hosted PHP applications and developer tools, not a general marketplace crowd.
Client Work
Real sites, built and shipped
A look at web development projects delivered for real clients. Designed, coded, and launched personally, no templates, no agencies in between.
How ownership works
Buy once, run it yourself, keep it
The same terms on every product. This is the part most marketplaces leave vague.
One payment, not a subscription
The version you buy stays yours. There is no renewal, no seat count and no licence server to phone home to.
Three years of updates, at least
I commit to shipping every new version, bug fix and security patch for that product free for at least three years after you buy. SevinHub started trading in September 2026, so that is a promise I am making, not a track record I can show you yet.
White label on most products
Rebrand it and run it for your own clients. Reselling under your own name is allowed where the extended licence covers it.

Common Questions
Everything you'd ask before buying
Why "Hub"? What does that actually mean?
SevinHub is one central hub where any business can replace monthly SaaS tools with scripts they own outright. Pick what matches your need, install on your hosting, stop paying rent on your own operations.
What do I actually get after I buy?
Within seconds: a one-time download link, your signed
SVH-XXXX-XXXX-XXXX-XXXX license key, and a printable PDF invoice. Re-downloadable anytime from your dashboard.Will this run on my cPanel / shared hosting?
Yes. Pure PHP, no Composer, no Node.js, no Docker. PHP 7.4+ and MySQL/MariaDB is all you need. If it doesn't run on your host, I'll fix it or refund you.
What does "3+ years of free updates" mean?
For at least 3 years after purchase, every new version of that product, bug fixes, security patches, features, is yours at no extra cost.
Can I rebrand and resell to my own clients?
For products marked white-label, yes, buy the extended license and rebrand, install for multiple clients, and resell.
How do I pay? Do you take crypto?
Card (Stripe), crypto (NOWPayments, BTC, ETH, USDT and more), and EU SEPA bank transfer. Delivery is automatic except bank transfer (manual within hours).
What if something breaks or I need help installing?
Open a ticket or message me via the live chat widget, it goes straight to my Telegram. Typical reply under 4 hours EU business hours. Install help is free.
Do you build custom software or do security work?
Yes, see Services and Cybersecurity. Custom PHP apps, white-label scripts, authorized pen testing, security reviews.
Refund policy?
Digital products are non-refundable once delivered. But: if it doesn't work on a supported hosting setup, or is materially different from the description, 100% refund, no friction.
Pillar 3 · Services
Two kinds of work, done to order
Small scope, direct contact, a fixed quote before anything starts. You are talking to the person who writes the code.
Custom software
A PHP and MySQL application built around how you actually work, or an existing system extended and fixed. Delivered on your hosting, with the source code, branded as yours. White label is available on most of the Hubs.
