Acceptable Use Policy

Chordalia Systems LLC  ·  Last updated: May 2026

The short version: Use Chordalia Systems software on content you have the legal right to process, on machines you control or are authorized to use. Don't use it for anything illegal, don't use it to attack other people's systems, and don't try to circumvent its license enforcement. We don't see your data, so we won't catch most violations ourselves — but if a violation is reported to us we will act on it.

1. Scope

This Acceptable Use Policy (“AUP”) applies to all Chordalia Systems software products — Arion today, and Chordium and Cadenzium when they ship — whether you use the free Personal edition or a paid Family or Archive license. It supplements the End User License Agreement and governs the kinds of content you may process with the software and the manner in which you may operate it.

Because Chordalia Systems software runs entirely on infrastructure you control, we have no technical visibility into how you use it. This AUP defines the contractual limits on that use; enforcement is reactive (we act on credible reports) rather than proactive (we don't monitor your activity, ever).


2. Content you may process

You may use Chordalia Systems software to index, search, and analyze:


3. Content you may NOT process

You may not use Chordalia Systems software to index, search, analyze, or otherwise process:


4. How you may operate the software

You may not:


5. Reports of suspected abuse

If you become aware of someone using Chordalia Systems software in violation of this AUP — for example, a leaked license file being redistributed, or our software being used to process illegal content — please report it to abuse@chordalia.com. Include enough detail for us to investigate; we treat reports confidentially.

We will investigate credible reports and may take any action we judge appropriate, including (where the violator is an identifiable customer) terminating the offending license under Section 10 of the EULA, refusing future sales to the same customer, or cooperating with law-enforcement requests consistent with applicable law.


6. Updates to this policy

We may update this AUP from time to time as patterns of misuse evolve or as we learn from operating experience. The current version is always available at www.chordalia.com/aup.html. Material changes will be reflected in the “Last updated” date at the top of this page. Continued use of Chordalia Systems software after an update constitutes acceptance of the revised AUP.
