REVENUE-BASED SPONSORSHIP LICENSE
Version 1.0, 20 September 2026

Copyright (c) 2026 oatsncrows

IMPORTANT NOTICE

This is a custom source-available license. It is not an Open Source Initiative
approved open-source license. It grants broad rights subject to the revenue-
based sponsorship obligation below. 

1. DEFINITIONS

"Software" means this repository and the source code, documentation, and
other materials distributed with it under this license.

"You" means an individual or a legal entity exercising rights under this
license. For a legal entity, "Your Revenue" includes the consolidated gross
revenue of that entity and its controlled affiliates. For an individual, it
means the individual's gross income from all sources.

"Annual Revenue" means Your gross worldwide revenue or gross income during
the most recently completed twelve-month period, determined using the same
accounting method You ordinarily use for tax or financial reporting. Revenue
is measured before deductions for costs, expenses, taxes, or distributions.

"Use" means using, copying, modifying, displaying, executing, distributing,
or making the Software available as part of a product, service, or internal
operation.

"Upstream Repository" means the repository from which You obtained the
Software, or, if You obtained it from a redistribution, the original public
repository identified in that distribution's attribution or source history.

2. GRANT OF RIGHTS

Subject to this license, the copyright holder grants You a worldwide,
non-exclusive, royalty-free, perpetual license to Use the Software for any
purpose, including commercial purposes; to modify it; and to distribute
original or modified copies.

You may sublicense portions of a larger work that do not consist of the
Software, but You may not remove or weaken this license for the Software.

3. REVENUE THRESHOLD AND SPONSORSHIP

If Your Annual Revenue is less than USD 300,000, You owe no sponsorship
payment under this license.

If Your Annual Revenue is USD 300,000 or more, You must sponsor the Upstream
Repository once for each completed twelve-month period in which You Use the
Software. The sponsorship amount is the percentage in the highest applicable
band below multiplied by Your entire Annual Revenue for that period:

  Annual Revenue                         Sponsorship rate
  USD 300,000 to less than USD 1,000,000       1.00%
  USD 1,000,000 to less than USD 10,000,000     0.50%
  USD 10,000,000 to less than USD 100,000,000   0.25%
  USD 100,000,000 or more                       0.10%

The rate decreases as Annual Revenue increases, but the calculation is not
progressive: the applicable rate applies to the entire Annual Revenue. The
minimum payment is USD 1,000 once the threshold is reached.

Payment must be made within ninety days after the end of the applicable
twelve-month period through the sponsorship or donation mechanism designated
by the Upstream Repository. If no mechanism is designated, You must contact
the copyright holder and make a commercially reasonable effort to arrange
payment. Payment must identify this Software and the period covered.

If the Upstream Repository has multiple maintainers, the sponsorship is made
to the repository's designated maintainer or organization, not separately to
each contributor.

4. NOTICE AND SOURCE

You must retain this license and all copyright, attribution, and warranty
notices with every copy or substantial portion of the Software. If You
distribute a modified version, You must clearly mark that You modified it.

If You distribute the Software or a modified version in object-code form,
You must provide the corresponding source code or a stable, accessible means
to obtain it for at least three years after distribution.

5. COMPLIANCE INFORMATION

Upon reasonable written request no more than once per year, You must confirm
whether Your Annual Revenue reached the threshold and, if so, the applicable
revenue band and sponsorship date. You need not disclose tax returns or
confidential financial records.

6. TERMINATION

The rights granted by this license terminate automatically if You materially
breach it and fail to cure the breach within thirty days after receiving
notice. Rights terminate immediately if You intentionally evade the
sponsorship obligation. Rights are reinstated if the breach is cured, unless
the copyright holder permanently terminates them in writing.

7. DISCLAIMER AND LIMITATION OF LIABILITY

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTIES OR CONDITIONS OF ANY
KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR
PURPOSE, AND NON-INFRINGEMENT. TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE
COPYRIGHT HOLDER IS NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL,
CONSEQUENTIAL, OR EXEMPLARY DAMAGES ARISING FROM THIS LICENSE OR THE SOFTWARE.

8. GOVERNING LAW

This license is governed by the laws of the jurisdiction in which the
copyright holder resides, without regard to conflict-of-law rules. If any
provision is unenforceable, it will be narrowed only as much as necessary and
the remaining provisions will continue in effect.
