Version 1.0
SPDX expression identifier: LicenseRef-Hyperfold-Freeware

Copyright (c) 2026 Lorenzo Fritzsch.
All rights reserved except as expressly granted below.

1. Scope and ownership

"Licensor" means the copyright holder identified above. "Software" means the
Hyperfold software and accompanying documentation distributed by Licensor with
this license, excluding components separately licensed by third parties.
"You" means the person or legal entity exercising rights under this license.

The Software is licensed, not sold. Licensor retains ownership of the Software
and all rights not expressly granted. This is a proprietary license and does
not require Licensor to provide source code.

2. Free use

Subject to this license, Licensor grants You a worldwide, non-exclusive,
royalty-free license for the duration of the applicable intellectual property
rights to download, install, copy, run, and use the Software for any lawful
purpose, including personal, academic, research, educational, governmental,
nonprofit, commercial, and production purposes.

You may use the Software on any number of devices, processors, accelerators,
servers, containers, virtual machines, and cloud environments, for Yourself
or third parties. You may offer paid or unpaid products, hosted services,
APIs, and computation services using it, including services that compete with
Licensor's services. No registration, usage reporting, or license fee is
required by this license.

3. Integrations and results

You may develop, use, modify, distribute, and sell independently written
applications, wrappers, bindings, plug-ins, and custom kernels that interact
with the Software through its interfaces. Calling, importing, or linking to
the Software as distributed does not, by itself, violate the modification
restriction in Section 5 or subject Your independent code to this license.

You may choose the license for Your independent code. Any included copy of
the Software remains governed by this license. Licensor claims no ownership
of Your data, numerical results, or other output merely because the Software
was used to process or produce them. This does not grant additional rights
to Software code or documentation copied into an output.

You may test and benchmark the Software and publish the methods and results
without Licensor's prior approval.

4. Redistribution

You may copy and redistribute unmodified copies of the Software, with or
without charge, separately or as part of applications, installers, containers,
virtual machine images, or other products. Public and private package
repositories, mirrors, and caches, including PyPI and the Python Software
Foundation, may host, reproduce, transmit, publish, and redistribute such
copies without further permission or payment to Licensor.

All redistributed copies must include this license and retain applicable
copyright, attribution, and third-party notices. You must not misrepresent
the Software's origin or claim Licensor endorses Your product or service.
Recipients receive their rights to the Software directly from Licensor under
this license. Terms governing Your own products must not remove or restrict
those rights in the included Software.

Ordinary installation, extraction from a wheel, bytecode generation,
compression, relocation, and repackaging are permitted where they do not
otherwise alter the Software's source or executable code or remove required
notices. No attribution in an application's user interface or advertising
is required by this license.

5. Restrictions and reserved rights

Except as expressly permitted above or by applicable law, You may not modify,
adapt, translate, or create derivative versions of the Software itself, or
distribute modified versions. You may not relicense the Software or remove
its copyright, license, or attribution notices.

You may not reverse engineer, decompile, or disassemble the Software except
to the extent permitted by applicable law notwithstanding this restriction.
Nothing in this license limits rights that cannot lawfully be excluded,
including applicable rights concerning backup copies, observation, study,
testing, error correction, and interoperability. The express permissions
for integrations and benchmarking remain unaffected.

No trademark rights are granted except the right to identify the Software
accurately and reproduce notices required by this license.

6. Patents and third-party components

To the extent Licensor controls patent claims necessarily infringed by
exercising the expressly granted rights in the Software as distributed,
Licensor grants You a worldwide, non-exclusive, royalty-free license under
those claims to exercise those rights for the term of this license. No
license is granted to third-party patents or claims infringed only by Your
modifications or combinations beyond the Software's intended operation.

Third-party components remain governed by their respective licenses. This
license does not replace or restrict rights granted under those licenses.
Consult the accompanying third-party notices and license texts.

7. Duration and termination

These permissions cannot be withdrawn for a Software release already
received under this license while You comply with its terms. Licensor may
offer future releases, support, or hosted services under different terms;
doing so does not change Your rights to an existing licensed release.

Licensor may terminate Your rights for a material breach that remains
uncorrected 30 days after written notice describing the breach. On
termination, You must cease exercising the terminated rights and delete
copies except those retained as required by law or under non-excludable
legal rights. Termination does not terminate the rights of recipients who
received copies in compliance with this license and remain compliant.

Ownership, reserved rights, third-party terms, warranty and liability
provisions, and provisions intended to survive remain effective.

8. Warranty and liability

To the maximum extent permitted by applicable law, the Software is provided
"AS IS" and "AS AVAILABLE", without warranties or conditions of any kind,
express or implied, including merchantability, fitness for a particular
purpose, non-infringement, accuracy, or uninterrupted operation. Licensor
has no obligation under this license to provide support, updates, or fixes.

To the maximum extent permitted by applicable law, Licensor shall not be
liable for losses or damages arising from the Software or this license,
including loss of profits, data, business, or use, whether arising in
contract, tort, or otherwise, even if advised of their possibility.

Nothing excludes or limits liability for fraud, intentional misconduct,
gross negligence, death or personal injury caused by negligence, or any
other liability that applicable law prohibits excluding or limiting.
Mandatory consumer rights remain unaffected.

9. Applicable law and general terms

This license is governed by the laws of Spain, subject to any mandatory
protections and jurisdiction rules that apply to You. No exclusive forum
is imposed by this license.

If a provision is unenforceable, the remaining provisions continue to apply
to the extent permitted by law. Failure to enforce a provision is not a
waiver. This license governs the permissions granted here unless You and
Licensor enter into a separate agreement expressly providing otherwise.
