STARNET2 SOFTWARE LICENSE AGREEMENT
-----------------------------------
Revision: 2026-09-07

Plain-language summary - for convenience only
---------------------------------------------

This summary highlights the main permissions and restrictions. It is not
part of the license agreement and does not replace or modify its terms.
Read the full agreement below, which governs your use of the Software.

- Free for astrophotography: personal, educational, research and commercial
  processing, including paid and hosted services, without supplying
  customers with software/model copies. (Section 2)
- Your images remain yours: edit, share full-resolution images, sell prints
  and provide paid processing results. No credit is required. These uses
  remain subject to others' rights and the restrictions below. (Section 3)
- Integration is conditional: apps/scripts may run the supplied CLI as a
  separate process; supplied plugins may use their intended host interfaces.
  Downloads and updates must come directly from official sources linked on
  our website. Providers must identify the product, present the full terms
  and obtain affirmative acceptance before use. Direct use of weights or
  bypassing the supplied interfaces is not permitted. (Sections 2 and 5)
- Redistribution needs prior written permission: do not bundle, mirror,
  resell or distribute software/model copies, or incorporate them into
  another product, without approval. (Sections 2, 5 and 9)
  This includes hosting or serving copies from other websites, mirrors,
  redistribution caches, servers or distribution nodes.
- No model training without prior written permission: do not use software,
  weights/components or outputs for training, fine-tuning, distillation or
  generating/supplying training material, even for noncommercial research.
  Modified outputs are covered too. (Section 4)
- No development/testing of other products: do not use or supply software,
  components or outputs to develop, test, validate or improve other
  software/model products, commercial or noncommercial. This includes
  modified outputs, product assets, test fixtures and reference results.
  The permitted integration activities remain excepted. (Section 5)
- Reviews are allowed: lawful criticism, comparisons and published
  evaluations remain subject to the training/development restrictions.
  (Sections 3, 4 and 5)
- No warranties: the Software is provided as-is. Keep backups and check
  results. Liability limitations apply, subject to mandatory legal rights.
  (Section 6)
- Existing rights are preserved: third-party licenses, prior grants and
  mandatory rights still apply. Output restrictions survive termination;
  new terms do not retroactively replace earlier licenses. (Sections 7-9)

Full license agreement
----------------------

Please read this license agreement carefully. By installing or using the
Software, you agree to its terms. If you do not agree, do not install or use
the Software. Mandatory rights and separately granted licenses are
preserved as explained below.

1. Parties and Scope
   This agreement is between you and Mikita (Nikita) Misiura (the Licensor).

   "Software" means the product named above, including its executables,
   plugins, Licensor-provided code, neural-network weights and model files,
   and accompanying documentation supplied under this agreement.

   "Outputs" means images or other results produced by the Software,
   including starless, denoised and extracted-star images.

   This agreement covers use of the Software both directly and through
   another application or service.

2. Permitted Use
   The Licensor grants you a non-exclusive, non-transferable license,
   without a license fee, to install, run and make reasonable backup copies
   of the Software solely for astrophotography image processing, subject
   to this agreement. Permitted uses include personal, educational,
   research and commercial processing, including paid and hosted services,
   provided you do not supply customers with copies of the Software or
   its model files.

   Other applications and scripts may automate permitted image processing
   by running the supplied CLI executable as a separate process. Supplied
   plugins may be used through their intended interfaces in supported host
   applications.

   Integrations may help users download, install and update the Software
   directly from the official download sources linked on the Licensor's
   website. These integration activities do not require separate written
   permission, provided the conditions below are met.

   Providers of integrations or hosted services must clearly identify the
   Software by its product name as performing the relevant processing,
   make the full applicable agreement available for review, and obtain
   the user's affirmative acceptance before enabling use under those terms.
   Acceptance of the same terms need not be repeated; revised terms require
   renewed acceptance. The provider may rely on acceptance obtained through
   the Software's own acceptance mechanism.

   A provider's failure to identify the Software or present these terms
   does not grant additional permissions or waive the Licensor's
   restrictions. An integration that does not meet these conditions is
   not authorized by this section.

   Bundling or redistributing copies of the Software or its model files,
   or incorporating them into another product rather than invoking a
   separate installation, requires the Licensor's prior written permission
   (see section 9).

3. Your Images and Reviews
   You retain your existing rights in your input images. The Licensor
   claims no ownership of your images or Outputs merely because you use
   the Software.

   You may edit, publish, share and sell your own images and Outputs,
   including full-resolution files, prints and paid processing results,
   subject to rights held by others and sections 4 and 5.
   You do not need to credit the Software on your images.

   Lawful reviews, criticism, comparisons and publication of evaluation
   results are permitted without the Licensor's approval, subject to
   sections 4 and 5.

4. No Model Training
   Without the Licensor's prior written permission, you may not use the
   Software, its weights or other components, or any Outputs to train,
   fine-tune or distill any machine-learning model or other learned system.

   This includes generating or supplying training data, labels, targets
   or teacher predictions for that purpose, whether for yourself or others.
   It also includes pairing images produced by the Software with their
   original input images or other data for model training.

   The restriction applies to commercial and noncommercial activity,
   including academic and personal research, and is not limited to
   competing products.

   The restriction also applies to Outputs you alter, convert or combine,
   including through brightness adjustments, cropping or other
   post-processing. Permission to edit, publish or sell images does not
   allow you to use or supply them for model training.

   This is a condition of your use under this agreement, not a claim
   that the Licensor owns your photographs or independently created inputs.

5. Redistribution and Other Restrictions
   Redistribution, resale, sublicensing, mirroring, bundling or providing
   others with copies of the Software or its model files requires the
   Licensor's prior written permission, even if unchanged or free of charge.
   This includes hosting or serving copies through other websites, mirrors,
   redistribution caches, servers or distribution nodes.
   Direct others to the official download instead.

   You may not use or supply the Software, its components or Outputs to
   develop, test, validate or improve other software or machine-learning
   products, whether commercial or noncommercial. This includes using or
   supplying Outputs as product assets, test fixtures or reference results,
   even after modification.

   The integration activities permitted in section 2 do not, by themselves,
   violate this prohibition.

   This exception does not permit bundling, redistribution or incorporation
   of the Software or its model files into another product as described
   in section 2 without the Licensor's prior written permission.

   You may not extract, load or use the Software's weights or model files
   independently of the supplied executables or plugins, including in
   another inference engine, without the Licensor's prior written
   permission. Do not reverse-engineer or modify the Software to bypass
   its supplied interfaces or these restrictions. This does not prevent
   the supplied executables or plugins from loading their model files
   during permitted use.

   Do not remove proprietary or third-party notices, or modify, extract
   or repackage the Software to circumvent these restrictions.

   These restrictions do not limit permissions or mandatory exceptions
   expressly preserved by section 8.

6. Warranty and Liability
   TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SOFTWARE IS
   PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT EXPRESS OR IMPLIED
   WARRANTIES, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR
   PURPOSE AND NON-INFRINGEMENT.

   Results may contain errors or artifacts. Retain backups and evaluate
   whether results are suitable for your use.

   TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE LICENSOR IS NOT
   LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES,
   OR LOSS OF PROFITS, DATA OR BUSINESS ARISING FROM USE OF OR INABILITY
   TO USE THE SOFTWARE. Nothing excludes or limits liability or consumer
   rights that cannot lawfully be excluded or limited.

7. Termination
   This license continues unless terminated. You may terminate it by
   ceasing use and deleting your Software copies.

   The Licensor may terminate it for breach, subject to any notice or
   opportunity to cure required by applicable law. After termination,
   stop using and delete copies of the Software held under this agreement.

   You are not required to delete your own input images or Outputs.

   The restrictions in sections 4 and 5 on using or supplying Outputs
   survive termination, subject to section 8.

8. Other Licenses and Mandatory Rights
   Third-party components and separately licensed material remain subject
   to their own applicable licenses and notices. This agreement does not
   override those terms or impose extra restrictions on rights they grant.

   It does not revoke rights previously granted under another applicable
   license, including Creative Commons licenses.

   Nothing in this agreement restricts uses or rights that applicable law
   does not allow the Licensor to restrict. If a provision is unenforceable,
   the remaining provisions apply to the extent permitted by law.

9. Revisions and Permissions
   This revision applies to the Software copy supplied with it.
   Publishing new terms does not retroactively replace licenses granted
   for earlier copies. Updated copies may carry revised terms; review
   the agreement supplied with them.

   To request additional permissions, contact the Licensor through the
   official website listed above. Permission must be obtained in writing
   before the proposed use.

   This agreement does not transfer ownership of the Software.
