SXS SOURCE-AVAILABLE COMMERCIAL LICENSE
Version 1.0 — 29 August 2026

Copyright © 2026 Rasya Andrean and Science Experimental Technologies.
All rights reserved except as expressly granted below.

This license is a source-available license. It is not an Open Source Initiative
approved license and must not be represented as an open-source license.

1. PARTIES AND ACCEPTANCE

"Licensor" means Rasya Andrean and Science Experimental Technologies,
collectively. "You" means the individual or legal entity exercising rights
under this license. By copying, modifying, distributing, publicly displaying,
or using the Software, You accept this license. If You do not accept it, You
must not exercise those rights.

2. DEFINITIONS

"Software" means the SXS — SCIX Exoplanet Search source code, project-authored
documentation, configurations, models, and project-authored artifacts made
available with this license, including modified or derivative versions.

"Output" means a result, report, ranking, visualization, dataset, model,
analysis, or other work produced through material use of the Software.

"Project" means any product, service, research activity, publication,
consulting engagement, hosted offering, internal business process, or other
undertaking in which the Software or an Output is a material component.

"Commercial Use" means use primarily intended for commercial advantage,
monetary compensation, revenue generation, paid fundraising, or the operation
of a for-profit product or service. Commercial Use includes selling access to
the Software or an Output; providing paid analysis, consulting, hosting, or
support based materially on the Software; and using the Software in a revenue-
generating Project.

"Covered Revenue" means gross amounts actually received from Commercial Use,
less only refunds, chargebacks, and sales, value-added, or similar transaction
taxes separately stated and remitted to a government. Covered Revenue excludes
donations or grants that do not purchase access, services, deliverables, or
preferential rights involving the Software or an Output.

3. NON-COMMERCIAL GRANT

Subject to this license, Licensor grants You a non-exclusive, worldwide,
revocable-on-breach, non-transferable right to access, run, study, reproduce,
and modify the Software solely for personal, educational, evaluation, or
non-commercial research purposes. You may distribute unmodified or modified
source copies for those purposes only when You:

  a. include this license and the NOTICE file in full;
  b. preserve all copyright, attribution, funding, and trademark notices;
  c. identify material modifications and their dates; and
  d. do not impose terms that conflict with this license.

No sublicensing right is granted except the right to pass on an exact copy of
this license with a permitted distribution.

4. COMMERCIAL USE AND TEN-PERCENT ROYALTY

Commercial Use is permitted only while You comply with all of this section.

  a. You must notify Licensor at scix.official@gmail.com before beginning
     Commercial Use, identifying You, the Project, and a billing contact.

  b. You owe Licensor a royalty equal to ten percent (10%) of Covered Revenue.
     The royalty accrues when Covered Revenue is received.

  c. Within thirty (30) days after each calendar quarter, You must provide a
     statement showing Covered Revenue, permitted deductions, and the royalty
     calculation, and pay the royalty using Licensor's written instructions.

  d. If the Software is bundled with other material and no separate price is
     stated, You must allocate Covered Revenue in good faith according to the
     Software's relative fair-market contribution. The allocation must not be
     structured principally to avoid the royalty.

  e. You must retain complete supporting records for five (5) years. No more
     than once per calendar year, Licensor may have an independent accountant
     inspect relevant records on reasonable notice and under confidentiality.
     Licensor bears the audit cost unless an underpayment greater than five
     percent (5%) is found, in which case You bear the reasonable audit cost.

  f. A separate signed commercial agreement may replace or modify this section.
     No email, purchase order, or informal statement changes these terms unless
     it expressly says so and is signed by Licensor.

5. ATTRIBUTION, PUBLICATIONS, PROJECTS, AND AWARDS

Every distributed copy, public deployment, public Project description, and
publicly shared Output must provide clear and reasonably prominent attribution
substantially in this form:

  "Built with SXS — SCIX Exoplanet Search, created by Rasya Andrean under
  Science Experimental Technologies."

The attribution must link to
https://github.com/Science-Experimental-Technologies/Exoplanet-Search when the
medium supports links. Academic or technical publications must also cite the
release using CITATION.cff and cite the relevant upstream mission data.

If a Project, Output, or result materially enabled by the Software is submitted
for or receives a prize, award, grant recognition, competition placement, or
formal public distinction, You must acknowledge SXS, Rasya Andrean, and Science
Experimental Technologies in the submission or public announcement to the
extent the applicable rules permit. Attribution does not imply endorsement.

You may not remove creator credit, obscure the Software's role, or claim that
You created the unmodified Software or Licensor's original research results.

6. CONTRIBUTIONS AND MODIFICATIONS

If You intentionally submit a patch, pull request, or other contribution to an
official SXS repository, You represent that You have the right to submit it and
grant Licensor a perpetual, worldwide, irrevocable, royalty-free,
transferable, sublicensable license to use, reproduce, modify, distribute,
commercialize, and relicense that contribution. You retain copyright in Your
original contribution and must be credited according to repository records.

A modified or derivative distribution must state that it is modified, name
its maintainers, preserve the creator attribution required by section 5, and
must not imply official status or Licensor endorsement.

7. PROHIBITED USES

You may not:

  a. use the Software without the attribution required by section 5;
  b. conduct Commercial Use without the reporting and royalty obligations in
     section 4 or a separate signed agreement;

     copyright notices, or authorship information;

9. TERMINATION

Your rights terminate automatically if You breach this license. For a first
non-willful breach, rights are reinstated if You fully cure it within thirty
(30) days after discovering it or receiving notice. Royalty, recordkeeping,
attribution, ownership, disclaimer, liability, and payment obligations survive
termination. Licensor may seek injunctive relief and any other lawful remedy.

10. DISCLAIMER OF WARRANTY

THE SOFTWARE AND OUTPUTS ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS
FOR A PARTICULAR PURPOSE, ACCURACY, NON-INFRINGEMENT, OR SCIENTIFIC VALIDITY.

INDEPENDENT REVIEW OF DATA, METHODS, RESULTS, AND REGULATORY OBLIGATIONS.

11. LIMITATION OF LIABILITY

TO THE MAXIMUM EXTENT PERMITTED BY LAW, LICENSOR WILL NOT BE LIABLE FOR ANY
INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, CONSEQUENTIAL, OR PUNITIVE DAMAGES,
OR FOR LOST PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS INTERRUPTION, ARISING
FROM THE SOFTWARE, OUTPUTS, OR THIS LICENSE. LICENSOR'S TOTAL LIABILITY WILL
NOT EXCEED THE AMOUNT YOU PAID LICENSOR UNDER THIS LICENSE DURING THE TWELVE
MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM.

12. GOVERNING LAW AND GENERAL TERMS

This license is governed by the laws of the Republic of Indonesia, without
regard to conflict-of-law rules. Courts of competent jurisdiction in Jakarta,
Indonesia have exclusive jurisdiction, unless a signed commercial agreement
states otherwise. If a provision is unenforceable, it will be limited to the
minimum extent necessary and the remainder will continue in effect. A waiver
must be written and signed by Licensor. This license and any signed commercial
agreement are the complete terms concerning the rights granted here.

13. LICENSE HISTORY

This license governs the repository revision in which it appears and later
revisions that expressly retain it. Copies already received under an earlier
license remain governed by the license attached to those copies. In particular,
rights validly granted for the tagged public release v1.0.0 under the MIT
License are not retroactively withdrawn.
