End User License Agreement

Version 1.2 — effective September 22, 2026.

AirCode Ø is operated by Spartacus Lab Sàrl, Switzerland.
CHE-329.911.786

This End User License Agreement (“Agreement”) is a binding contract between you (“Licensee”) and Spartacus Lab Sàrl (“Licensor”), governing the use of the AirCode Ø software, in object-code / packaged form only, together with its documentation and updates (the “Software”).

By selecting Agree and continue, installing, or using the Software, you accept this Agreement, including the required product usage statistics described in Section 8. If you do not accept it, do not install or use the Software.

1. Definitions

  • Machine — one physical or virtual computer on which the Software server component is installed.
  • Free Account — an active AirCode Ø account used to identify a person or device for managed services; it is not a paid subscription.
  • Self-managed Product — the Software running on a Machine supplied and controlled by Licensee, using AI-provider accounts or credentials supplied by Licensee.
  • Managed Services — centrally operated services such as managed Relay and authenticated Marketplace actions that are separate from local operation of the Self-managed Product.

2. License grant

Subject to continuous compliance with this Agreement, Licensor grants Licensee a non-exclusive, non-transferable, non-sublicensable license, during the term of this Agreement, to:

  1. install and run the Software server component on Machines under Licensee’s control, for Licensee’s own use and, if Licensee is an organization, use by its authorized personnel;
  2. install and use the desktop and mobile client applications on devices under those users’ control; and
  3. receive and install updates that Licensor makes available for the Software.

3. Restrictions

Except to the extent a restriction is unenforceable under mandatory applicable law, Licensee shall not, and shall not permit any third party to:

  • copy (other than reasonable backups), distribute, publish, sell, rent, lease, lend, or host the Software for the benefit of third parties;
  • provide access to the Software to persons who are not authorized by Licensee under Section 2, including making the server component available as a service to third parties;
  • reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of the Software, except and only to the extent expressly permitted by applicable law notwithstanding this limitation;
  • modify, adapt, translate, or create derivative works of the Software;
  • remove, alter, or obscure proprietary notices, or circumvent or attempt to circumvent authentication, authorization, security, abuse-prevention, or Managed Services access controls;
  • use the Software to develop a competing product, or publish benchmarks of the Software without Licensor’s prior written consent.

4. Free product and managed services

The Self-managed Product is currently licensed without a product fee. It does not require a card, product key, activation, paid subscription, or time-limited trial. Licensee supplies the Machine and is responsible for obtaining and paying for any supported third-party AI account, subscription, or API usage.

Local, LAN, private-network, customer-operated Relay, and direct self-hosted use do not require a Free Account. Managed Relay and authenticated Marketplace actions require an active Free Account and remain subject to documented device, concurrency, namespace, security, moderation, availability, and fair-use limits. Marketplace publishing additionally requires the documented identity, ownership, source, review, and moderation checks.

Managed hosting and managed AI credits are not currently offered under this Agreement. If Licensor later offers either service, its price, scope, and additional terms will be stated separately. No future service is implied by the Free Account or this license grant.

5. Accounts, offline use, and legacy license records

The Self-managed Product remains usable without contacting a licensing service. It does not enter a restricted mode because a product key, trial, subscription, or validation grace is missing or expired.

Older installations may retain signed license keys, trial files, activation records, compatibility commands, or licensing-service records. Those records may be inspected or removed for support and historical continuity, but they do not grant, restrict, or revoke current Software functionality. Data sent only when Licensee explicitly invokes a legacy licensing operation is described in the Privacy Policy.

A Free Account is required only for the Managed Services documented as account bound. Account suspension or deletion can stop new account-bound actions without removing Licensee’s local projects or turning the Self-managed Product into a paid or restricted edition.

6. Third-party and open source components

The Software incorporates third-party and open source components licensed under their own terms, listed in the NOTICE file distributed with the Software. Those terms apply to those components; this Agreement applies to the Software as a whole.

Some distributions of the Software also redistribute agent CLI executables published by third parties, unmodified and as published, so that the Software runs the versions it was tested with. Those executables are identified in the NOTICE file with their publisher and license. They are not licensed to Licensee under this Agreement: each remains governed exclusively by its own publisher’s terms, and this Agreement grants no right in them beyond running the copy distributed with the Software.

Whether an agent CLI is redistributed with the Software or installed by Licensee, Licensee authenticates with the corresponding vendor using Licensee’s own credentials and is responsible for holding valid accounts with that vendor. Licensor neither pays for, resells, nor intermediates that usage. Licensor is not affiliated with, endorsed by, or partnered with those publishers, and their names are used only to identify their software.

7. Updates and support

Updates that Licensor publishes for Licensee’s release channel are included. Licensor may change or discontinue features with commercially reasonable notice. Support terms, if any, are described on https://aircodezero.com or in separate terms for a future managed service.

8. Required product usage statistics

Use of the Software includes collection of the basic, pseudonymous product usage statistics described in the Privacy Policy. This processing is a condition of the license and has no separate in-product opt-out. Licensee must not install or use the Software if Licensee does not accept this processing.

Product usage statistics are restricted to allowlisted operational events and coarse technical context. They never contain prompts, messages, source code, commands, terminal input or output, file contents or paths, project names, session names, server addresses, credentials, account identifiers, feedback text, or email addresses. The current providers, exact event categories, retention periods, international transfers, and applicable rights are described in the Privacy Policy.

9. Intellectual property

The Software is licensed, not sold. Licensor and its suppliers retain all right, title, and interest in and to the Software. Feedback voluntarily provided by Licensee may be used by Licensor without restriction or compensation.

10. Term and termination

This Agreement begins when Licensee accepts it and continues until terminated. It terminates automatically upon material breach that remains uncured fourteen (14) days after written notice, and immediately upon breach of Section 3. Upon termination, the rights granted in Section 2 cease; Licensee’s project data, which is stored on Licensee’s own machines, remains Licensee’s property and remains accessible outside the Software. Sections 6, 9, 11, 12, and 13 survive termination.

11. Warranty disclaimer

THE SOFTWARE IS PROVIDED “AS IS” AND “AS AVAILABLE”. TO THE MAXIMUM EXTENT PERMITTED BY LAW, LICENSOR DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. THE SOFTWARE ORCHESTRATES AUTONOMOUS CODING AGENTS THAT MODIFY FILES AND EXECUTE COMMANDS; LICENSEE IS SOLELY RESPONSIBLE FOR THE CONFIGURATION OF PERMISSION MODES, FOR BACKUPS, AND FOR REVIEWING AGENT OUTPUT.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, LICENSOR SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, NOR FOR LOSS OF DATA, PROFITS, OR BUSINESS, ARISING OUT OF OR RELATED TO THIS AGREEMENT. LICENSOR’S AGGREGATE LIABILITY SHALL NOT EXCEED THE AMOUNTS PAID BY LICENSEE FOR THE SOFTWARE IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM. NOTHING IN THIS AGREEMENT EXCLUDES LIABILITY THAT CANNOT BE EXCLUDED UNDER APPLICABLE LAW.

13. General

This Agreement is governed by the substantive laws of Switzerland, excluding its conflict-of-law rules. Subject to mandatory consumer protections and mandatory venues, exclusive venue lies with the competent courts at the Licensor’s registered office in Switzerland. If any provision is held unenforceable, the remainder stays in effect. This Agreement is the entire agreement regarding the Software and supersedes prior discussions. Licensor may assign this Agreement in connection with a merger or sale of assets; Licensee may not assign it without Licensor’s written consent, not to be unreasonably withheld.
