The commercial license of the CUZY modules for HumHub: one license key for one installation, with annual or lifetime maintenance (updates and support), under Irish law.
You are not obliged to choose this license. Every CUZY module is offered under two licenses, and you choose the one you rely on. The commercial license below is the one you buy on cuzy.app: it comes with the license key, the installation and the updates through the HumHub marketplace, and the support, for one installation. The GNU Affero General Public License v3 is the other option: it is free, needs no purchase and nothing to accept, and lets you use, modify and redistribute the module under its conditions, including sharing the source code of a modified version with its users. Buying or renewing the commercial license takes nothing away from the AGPL option, which remains available to you at any time, even after the commercial license has ended. The box you tick at checkout accepts the terms of your purchase; it does not waive the AGPL. The dual licensing page compares the two options.
This version applies to licenses purchased on or after 8 October 2026. Licenses purchased earlier remain governed by the version in force at the time of purchase (Version 1.0 of 1 September 2020, available at https://www.cuzy.app/legal/licence-1-0), even if the Licensee installs an Update that contains this file. A license governed by an earlier version moves to this version in either of the following cases:
community.example.com), under which the Installation is served, together with its sub-domains used for the same Installation (for example for Non-Production Copies). The Licensee may change the Licensed Domain for the same Installation (for example on rebranding or migration) by notifying the Licensor (e-mail is sufficient); the Licensor will update its records and, where necessary, reissue the License Key.This License governs the use of the Software on the terms set out here. It covers the Software only. It grants no rights to HumHub or to third-party components, which remain subject to their own licenses, and it cannot override those licenses (Section 1.2). Any use not expressly permitted is excluded, without prejudice to the AGPL option in Section 1 and to non-excludable statutory rights (Clause 12).
Subject to payment of the price and compliance with this License, the Licensor grants the Licensee a non-exclusive, worldwide right to:
Modifications. The Licensee may adapt, configure, translate and otherwise change the Software according to its needs, delete components it does not want, and combine the Software with other software. A Modified Version remains "Software" for the purposes of this License and is subject to its terms. It may only be used in the licensed Installation and its Non-Production Copies. The Licensor may decline support for, and is not responsible for defects in, a Modified Version or an installation from which components have been removed.
Independent Extensions. The Licensee owns its Independent Extensions and may use, distribute and license them under any terms, including proprietary and commercial licenses. The Licensor claims no rights in them. The Licensor is not liable for Independent Extensions or for their interaction with the Software.
Except as expressly permitted by this License, the Licensee shall not:
These restrictions apply only to use under this License. They do not limit any rights under the AGPL (Section 1) or any non-excludable statutory rights (Clause 12).
Customers. Where a buyer (for example an agency, consultant or managed-service provider) purchases a license for an Installation operated for a customer, the customer is the Licensee and the buyer acts as its agent and Authorised Person: the buyer may install, operate and maintain the Software on the customer's behalf, and the customer holds the license. The buyer shall identify the customer to the Licensor on request, and the Licensor may record the customer as the Licensee and reissue the License Key accordingly. The buyer confirms that it is authorised to accept this License on the customer's behalf. One license cannot serve both the buyer's own Installation and a customer's Installation; a buyer serving several customers needs one license per customer Installation.
Transfer. The Licensee may transfer the Software (modified or not) together with the license to another party if:
On transfer, the License Key, the Licensed Domain and the remaining Maintenance Period pass to the new licensee. The Licensor may reissue the License Key for that purpose, and the new licensee may change the Licensed Domain as set out in Clause 1.
Price and delivery. Prices, renewal fees, payment and the ordering process are governed by the terms of the store or marketplace through which the license was purchased, to the extent they are consistent with applicable law. Any statutory cancellation, refund and conformity rights of a Consumer, including under the Consumer Rights Act 2022 (Ireland), apply regardless of this License and of the store or marketplace terms; the store or marketplace informs the Consumer about those rights before purchase. The license takes effect once payment has been received. The Software is delivered by making it available for installation through the HumHub marketplace with the License Key.
Maintenance. During the Maintenance Period the Licensor will maintain the Software: it will fix Bugs as set out in "Bug-fix commitment" below, fix security issues of which it becomes aware, and use reasonable efforts to keep the Software compatible with the HumHub versions stated as supported in the marketplace listing, and it will publish the resulting Updates through the HumHub marketplace. The Licensor decides at its sole discretion whether and when to add new features and which future HumHub versions to support. The Licensor may stop maintaining the Software altogether. In that case it will announce the end of maintenance in the marketplace listing or on its website with reasonable advance notice where practicable, will not charge renewal fees for periods after the announced end of maintenance, and will use reasonable efforts to keep the last version available for download by licensees for at least 12 months after that date or to transfer maintenance to a successor.
Bug-fix commitment. During the Maintenance Period, the Licensor will fix a Bug reported by the Licensee within 14 calendar days. The period starts when the Licensor has received, through https://cuzy.app/support, a report that allows it to reproduce the Bug (in particular the versions of the Software and of HumHub concerned and the steps to reproduce it), and it is extended for as long as the Licensor is waiting for information or access it has asked the Licensee for. The fix is published as an Update available to all Licensees with a valid License Key. Until that Update is published, the Licensor may instead provide a workaround that restores the affected function. If the Licensor misses this deadline, it will continue to work on the fix with priority and, where the Maintenance Period is a fixed term, will extend the Licensee's Maintenance Period by the number of days by which the deadline was exceeded. Where an error is caused by HumHub itself, the Licensor may report it to the HumHub developers or provide a workaround, but no deadline applies.
Updates. Updates (including security fixes) are made available through the HumHub marketplace only to Installations with a valid License Key, that is during the Maintenance Period. The Licensor is not obliged to provide Updates in any other way. The Licensor may restrict access to its store, private repository, marketplace delivery mechanism, License Keys, Updates and support to Licensees with a valid Commercial License; this operational restriction does not limit the rights of anyone who has received a copy of the Software under the AGPL (Section 1.4). Updates are covered by the version of this License that governs the license at the time the Update is received (see the beginning of this Section 2); installing an Update does not by itself change that version. New products, extensions or separately listed major versions may be offered separately, free of charge or for a fee.
Renewal; end of the Maintenance Period. Where the Maintenance Period is a fixed term, the Licensee may extend it by paying the renewal fee before or after it ends; the Licensor may require that a lapsed Maintenance Period be renewed from the date it ended. Where the Maintenance Period is unlimited ("lifetime"), no renewal fee is due, and the Licensor may not later make Updates for that license conditional on payment, other than for new products, extensions or separately listed major versions as set out above. "Lifetime" refers to the lifetime of the Software as a maintained product, not to the lifetime of the Licensee or of the Licensor's business; it ends when the Licensor stops maintaining the Software under the preceding paragraph. When the Maintenance Period ends, whether through non-renewal or because the Licensor has stopped maintaining the Software, the License Key expires and the following applies:
Renewing the Maintenance Period (where it is a fixed term) reactivates the License Key, with access to the then-current version, Updates and support.
Support. During the Maintenance Period, support is provided as described at https://cuzy.app/support. Apart from the bug-fix commitment above, and unless a separate support agreement exists, the Licensee has no claim to a particular response time or result. Support does not cover HumHub itself, third-party modules, hosting, or the Licensee's own modifications.
All rights in the Software (including images, animations, texts and documentation) and in all copies remain with the Licensor and its licensors and are protected by copyright. This License grants a right of use only and does not transfer ownership. Rights in the Licensee's own data and in its Independent Extensions remain with the Licensee.
10.1 Warranty. The Licensor's commitment regarding defects in the Software is to fix Bugs under Clause 7 (maintenance and bug-fix commitment), which applies during the Maintenance Period. The remedies set out there are the Licensee's sole remedies for defects in the Software. Errors in software cannot be completely ruled out; the Licensor does not warrant that the Software is free of errors, will operate uninterrupted, meets the Licensee's particular requirements or works with other programs, extensions or HumHub versions not stated as supported in the listing. The Licensee is responsible for selecting the Software and for the results obtained from its use. This commitment is voluntary and contractual; it does not limit any statutory conformity rights, remedies, cancellation rights or other protections of Consumers (Clause 10.6).
10.2 Exclusion of implied terms. Except as expressly set out in this License, and to the fullest extent permitted by law, all conditions, warranties, representations and other terms that might otherwise be implied by statute, common law or otherwise (including any implied terms as to merchantable quality, satisfactory quality, fitness for a particular purpose or non-infringement) are excluded.
10.3 Liability that cannot be excluded. Nothing in this License excludes or limits the Licensor's liability for: (a) death or personal injury caused by its negligence; (b) fraud or fraudulent misrepresentation; (c) liability under the Liability for Defective Products Act 1991; or (d) any other liability that cannot be excluded or limited under applicable law.
10.4 Excluded losses. Subject to Clause 10.3, the Licensor shall not be liable to the Licensee, whether in contract, tort (including negligence), breach of statutory duty or otherwise, for: (a) loss of profits, revenue, business, contracts, goodwill or anticipated savings; (b) loss or corruption of data or of information, to the extent it could have been avoided by the Licensee keeping reasonable backups; (c) business interruption; or (d) any indirect, special or consequential loss, in each case arising out of or in connection with this License or the Software, even if the Licensor was advised of the possibility of such loss.
10.5 Cap. Subject to Clauses 10.3 and 10.4, the Licensor's total aggregate liability to the Licensee arising out of or in connection with this License and the Software, whether in contract, tort (including negligence), breach of statutory duty or otherwise, shall not exceed the greater of (a) the price paid for the initial purchase of the license concerned and (b) the total amount paid by the Licensee to the Licensor for that license (initial price and renewal fees) in the 12 months preceding the event giving rise to the claim. The cap applies separately to each license and, for each license, to all claims in aggregate, whatever their number or legal basis. Where the Licensee holds several licenses, the cap for each is determined by the amounts paid for that license alone.
10.6 Consumers. If the Licensee is a Consumer, Clauses 7, 8.4, 10.1 to 10.5, 10.7, 10.8, 13.2 and 13.4 apply only to the extent permitted by applicable consumer protection law. Nothing in this License affects a Consumer's statutory rights, including rights under the Consumer Rights Act 2022 (Ireland) in respect of digital content and digital services, or the mandatory consumer protection law of the country in which the Consumer habitually resides.
10.7 Third-party items. The Licensor is not responsible for HumHub, third-party modules, themes, hosting or infrastructure, or for Independent Extensions, or for the Licensee's own modifications.
10.8 Demonstrations. Because the Software can be customised extensively, illustrations in demos, tests, product descriptions and project descriptions are for information only and do not form part of this License or constitute a warranty or representation unless expressly stated to do so.
Nothing in this License restricts rights that the law grants lawful users of software and that cannot be excluded by contract, in particular the rights under the Copyright and Related Rights Act 2000 (Ireland) and Directive 2009/24/EC to make a back-up copy, to observe, study and test the functioning of the Software, and to reproduce and translate code where indispensable for interoperability. Mandatory consumer protection law of the country in which a Consumer habitually resides also remains unaffected.
This License and any dispute or claim (including non-contractual disputes or claims) arising out of or in connection with it are governed by the laws of Ireland. The UN Convention on Contracts for the International Sale of Goods does not apply. If the Licensee is not a Consumer, the courts of Ireland have exclusive jurisdiction over any such dispute or claim. If the Licensee is a Consumer, this does not deprive the Consumer of the protection of mandatory provisions of the law of, or of the right to bring or defend proceedings in the courts of, the country in which the Consumer habitually resides.
