# Catena Community License

Catena Sustainable Use License, Version 1.0

Copyright (c) 2026 Marc-Antoine Lalonde. All rights reserved.

This license adapts the n8n Sustainable Use License (fair-code) model.
Catena Community is fair-code: the source is published and free to use
for your own internal business purposes, with one boundary -- you may not
offer Catena to third parties as a hosted or managed service. That
managed offering is Catena Business, the commercial edition.

## Acceptance

By using the software, you agree to all of the terms and conditions
below.

## Copyright License

The licensor grants you a non-exclusive, royalty-free, worldwide,
non-sublicensable, non-transferable license to use, copy, distribute,
make available, and prepare derivative works of the software, in each
case subject to the limitations and conditions below.

## Limitations

You may use or modify the software only for your own internal business
purposes or for non-commercial or personal use. "Your own internal
business purposes" means running the software for the benefit of you or
your company; it does not include providing the software, or its
functionality, to any third party.

You may distribute the software or provide it to others only if you do so
free of charge and for non-commercial purposes, and only together with a
copy of these terms.

You may not, whether for a fee or free of charge:

1. offer or provide the software, modified or not, to third parties as a
   hosted or managed service, where that service gives a third party
   access to any substantial set of the features or functionality of the
   software; or
2. operate, administer, or manage the software on behalf of a third
   party as a commercial offering.

For the avoidance of doubt, the prohibitions in (1) and (2) apply
regardless of who owns or controls the infrastructure the software runs
on, including where a third party owns the server. Running the software
for your own internal business purposes through a contractor acting
solely on your behalf is permitted; using the software to deliver a
service to third parties is not.

You may not alter, remove, or obscure any licensing, copyright, or other
notices of the licensor in the software. Any use of the licensor's
trademarks is subject to the Trademarks section below and applicable law.

## Trademarks

"Catena", the Catena name, and the Catena logo are trademarks of
Marc-Antoine Lalonde. This license grants you no right to use them. You may make a
nominative reference to Catena to identify the unmodified software. If
you distribute a modified version of the software, you must remove all
Catena trademarks and rename your version so that it is not confusingly
similar to Catena, and you must not represent that your version is
endorsed by or associated with the licensor.

## Enterprise (Business) modules

The Catena Business (Enterprise) modules are not covered by this license.
They are distributed separately as compiled, license-gated binaries from
catenahq/catena-ee and are not published as source. Nothing in this
license grants any right in or to those modules.

## Contributions

Unless you state otherwise, any contribution you intentionally submit for
inclusion in the software (a "contribution") is provided under the terms
of this license. In addition, you grant Marc-Antoine Lalonde a perpetual,
worldwide, non-exclusive, royalty-free, irrevocable license to use,
reproduce, modify, distribute, sublicense, and relicense your
contribution, in whole or in part, under this license and under any other
license terms, including proprietary or commercial terms (such as the
Catena Business modules). You represent that you are legally entitled to
grant this license for each contribution you submit.

## Patents

The licensor grants you a license, under any patent claims the licensor
can license, or becomes able to license, to make, have made, use, sell,
offer for sale, import, and have imported the software, in each case
subject to the limitations and conditions in this license. This license
does not cover any patent claims that you cause to be infringed by
modifications or additions to the software. If you or your company make
any written claim that the software infringes or contributes to
infringement of any patent, your patent license for the software granted
under these terms ends immediately. If your company makes such a claim,
your patent license ends immediately for work on behalf of your company.

## Notices

You must ensure that anyone who gets a copy of any part of the software
from you also gets a copy of these terms. If you modify the software, you
must include in any modified copies prominent notices stating that you
have modified the software.

## No Other Rights

These terms do not imply any licenses other than those expressly granted
in these terms.

## Termination

If you use the software in violation of these terms, such use is not
licensed, and your licenses will automatically terminate. If the licensor
provides you with a notice of your violation, and you cease all violation
of this license no later than 30 days after you receive that notice, your
licenses will be reinstated retroactively. However, if you violate these
terms after such reinstatement, any additional violation of these terms
will cause your licenses to terminate automatically and permanently.

## No Liability

As far as the law allows, the software comes as is, without any warranty
or condition, and the licensor will not be liable to you for any damages
arising out of these terms or the use or nature of the software, under
any kind of legal claim.

## Governing Law

These terms are governed by the laws of the Province of Quebec and the
federal laws of Canada applicable therein, without regard to conflict-of-
law rules. The courts of the Province of Quebec (judicial district of
Montreal) have exclusive jurisdiction over any dispute arising out of or
relating to these terms or the software.

## No Conversion to Open Source

Unlike a Business Source License, this license does not automatically
convert to an OSI-approved open-source license after any period of time.
The licensor may, at its sole discretion, release any version under
other terms.

## Definitions

The licensor is Marc-Antoine Lalonde, the entity offering these terms. The
software is the software the licensor makes available under these terms,
including any portion of it.

"you" refers to the individual or entity agreeing to these terms.

"your company" is any legal entity, sole proprietorship, or other kind of
organization that you work for, plus all organizations that have control
over, are under the control of, or are under common control with that
organization. Control means ownership of substantially all the assets of
an entity, or the power to direct its management and policies by vote,
contract, or otherwise. Control can be direct or indirect.

"your licenses" are all the licenses granted to you for the software
under these terms.

"use" means anything you do with the software requiring one of your
licenses.

"trademark" means trademarks, service marks, and similar rights.

Upstream applications deployed by Catena each carry their own license
(Nextcloud GPL, Rocket.Chat MIT, OnlyOffice AGPL, and so on); those are
unaffected by this file.
