Basic editorial direction of the website („Blattlinie“)
This website serves to present the services of Lumi-Systems.io in the field of software and
information technology: setup and operation of software platforms, project management with Work
Items and Kanban boards, automation of workflows using language models, creation and
maintenance of websites, software prototyping, development of custom software solutions, scripting
as well as hosting of applications. In addition, refurbished used devices with preinstalled
Linux operating system are offered.
In terms of content, we hold the view that software should belong to its users: open standards,
data sovereignty with the customer, no tie-in to licensing models. We report on the advantages of Linux and
open software, about our products and services as well as about our social commitment. An
AI support assistant is available for questions about the offering.
Dispute resolution
We are willing to participate in an out-of-court dispute resolution procedure before a
consumer dispute resolution body.
The general dispute resolution bodies for consumer transactions in Austria are responsible:
- Internet Ombudsman — for disputes arising from online transactions,
www.ombudsmann.at - Dispute Resolution for Consumer Transactions (Verbraucherschlichtung Austria),
www.verbraucherschlichtung.at
The procedure is free of charge for consumers and is completed within 90 days. The
participation does not exclude the ordinary legal process.
Note: The European Commission's former platform for
online dispute resolution (ODR platform) was discontinued. Regulation (EU) No. 524/2013 was by
The Regulation (EU) 2024/3228 was repealed with effect from 20. Juli 2025. A reference to it is therefore
no longer possible.
Social commitment
Lumi-Systems.io undertakes to donate 20 % of the monthly net profit from the sale of each device for
the support and care of cats in need. Donations are made as monetary and
in-kind donations (such as food or scratching posts) to animal shelters, rescue centres, care homes, cat cafés and
dedicated private individuals.
