Commercial License Terms

Last updated: 3 November 2026

Two licenses, two regimes. Bichon Community is free software under the AGPLv3. Bichon Pro and Bichon Enterprise are commercial editions governed by these terms and by the Terms of Service. If you have not purchased a Commercial License, only the AGPLv3 applies to your use of the Community edition.

1. Community edition

The Community edition is licensed under the GNU Affero General Public License, version 3. You may use, study, modify, and redistribute it under the terms of that license, including its source-code and network-use obligations. Nothing on this page limits rights granted to you by the AGPLv3. The Community edition is provided without warranty, as set out in sections 12 and 13 of the Terms of Service and in the AGPLv3.

2. Grant of license

Subject to payment of the applicable fees and your compliance with these terms and the Terms of Service, we grant you a non-exclusive, non-transferable, non-sublicensable license to install and run the edition of the Software stated in your license key (Pro or Enterprise) for your internal business purposes. The license is perpetual for the licensed edition, but it is limited by the deployment binding, account limit, and update window described below, and it may be terminated for breach as described in section 8.

The license is granted to the legal entity named in the order. It does not include the right to provide the Software to third parties as a hosted or managed service, except with our prior written consent.

3. Deployment binding, account limit, and editions

One deployment per license. A Commercial License is bound to the instance ID of a single deployment. The instance ID is generated on first start and stored in the deployment’s data directory. Moving or restoring that data directory to another server keeps the instance ID and the license remains valid. Deleting the data directory, losing the volume, or creating a new deployment produces a new instance ID and requires a new license.

Account limit. The license states a maximum number of accounts; unless stated otherwise, the default is 5 for Pro and 100 for Enterprise. Each email account and each view account configured in the Software counts toward that limit. The Software enforces the limit.

Editions. Pro and Enterprise are the same binary; the license key unlocks the edition stated in the key. Enterprise features are not available under a Pro key, and license keys are not interchangeable between editions.

4. Updates and renewal

A Commercial License includes updates released during the update window stated in the license — normally 12 months from issue. Builds whose release date falls after the update window will refuse to run under that license; the license continues to permit use of builds from within the window. You may extend the window with an annual update subscription. Renewal is optional: if you do not renew, you keep the perpetual right to run the builds you are entitled to, but you do not receive newer builds. We are not obliged to release updates, features, or security patches.

5. Evaluation

Unless we agree otherwise in writing, evaluation is limited to 30 days from first start and up to 2 accounts. Evaluation licenses are provided for testing, without warranty, and may be terminated earlier. When an evaluation ends, Pro and Enterprise features stop; the deployment continues with Community features. We do not delete your data, but an evaluation deployment must not be your only copy of anything you cannot afford to lose.

6. Restrictions

Except as expressly permitted by law or by the AGPLv3 for Community code, you must not:

  • copy, modify, distribute, sell, rent, lease, sublicense, or commercially exploit the Pro or Enterprise software or any part of it;
  • reverse engineer, decompile, disassemble, or attempt to derive the source code of the proprietary components, except to the extent a mandatory statutory right permits it;
  • remove or alter any copyright, license, or proprietary notices;
  • circumvent, disable, or interfere with license validation, account limits, update checks, or other technical restrictions;
  • use the Software to build or train a competing product or to develop a substantially similar substitute; or
  • use the Software in violation of applicable export control or sanctions laws.

7. License keys and revocation

License keys are personal to the licensed entity and must be kept confidential. Validation is offline: the Software verifies the key’s signature, edition, instance ID, account limit, and update window locally, without contacting us. We may revoke a license key if it was obtained fraudulently, if payment is reversed or never received, if it is used outside the licensed scope, or if required by law. Revoked keys stop working; we will give notice where practicable and a reasonable opportunity to cure, except in cases of fraud or unlawful use.

8. Termination

This license terminates automatically if you materially breach these terms and do not cure the breach within 14 days of written notice, or immediately if you infringe our intellectual property, circumvent license controls, or use the Software unlawfully. On termination you must stop using the Pro or Enterprise edition and remove it from your systems. Sections that by their nature should survive — including restrictions, intellectual property, warranty disclaimer, limitation of liability, and governing law — survive termination.

9. Warranty and liability

The Software is provided “as is”. The warranty disclaimer in section 12 and the limitation of liability in section 13 of the Terms of Service apply to every Commercial License and are incorporated into these terms by reference. In particular, we are not liable for loss of or damage to archived data, for the completeness or legal admissibility of any archive, or for your failure to maintain independent backups.

10. Third-party and open-source components

The Software includes open-source components that remain governed by their respective licenses. Where those licenses grant you rights that conflict with these terms, those licenses prevail for the components they cover. A list of components and licenses is available in the Software distribution. The AGPLv3 governs the Community edition and any AGPLv3-covered components; it does not grant rights to the proprietary Pro or Enterprise features.
