caldrix License Terms

Version 4, 2026-10-27. It replaces version 3 of 2026-10-26, which named the package caldrix.js before its npm name was chosen; version 3 replaced version 2 of 2026-10-16, which did not address the caldrix.js npm package (section 6); version 2 replaced version 1 of 2026-10-15, which named the company as a party before its registration.

These terms are an agreement between you and Jyothsna Muttineni (the "Licensor", "we"), acting for Caldrix GmbH, a company in formation in Zug, Switzerland. On its registration, Caldrix GmbH becomes the Licensor and takes over all rights and obligations under these terms. They govern your use of the caldrix software: the caldrix binary and the ld.lld linker shipped with it, the installer at caldrix.ai/install.sh, the caldrix container images, and the documentation (together, "the Software"). By downloading, installing or using the Software you accept these terms. If you do not accept them, do not use the Software. The npm package caldrix.js is not part of the Software; see section 6.

1. Definitions

Non-commercial use means use for personal purposes, research, education, evaluation, development or testing, where neither the use nor its output is part of a product, service or business operation.

Commercial use means any other use, including any production use and any use in connection with a commercial activity, such as running the Software for a product or service, for internal business operations, or to serve inference to third parties, whether paid or free of charge.

2. Free license for non-commercial use

The Licensor grants you a non-exclusive, non-transferable, non-sublicensable, worldwide license to install and use the Software for non-commercial use, free of charge and without time limit, subject to these terms.

3. Commercial license

Commercial use requires a separate written license agreement with the Licensor. Contact [email protected]. Until such an agreement is signed, these terms grant no right to commercial use.

4. Restrictions

You may not, except as these terms or a written agreement with the Licensor allow:

• distribute, sublicense, rent or lend the Software, or make it available to third parties, including as part of another product or as a hosted service;
• modify the Software or create derivative works of it;
• decompile, disassemble or reverse engineer the Software, except to the extent mandatory law, including Swiss copyright law on interoperability, permits it;
• remove or alter any notice of ownership or license in the Software.

5. Third-party components

The Software contains open-source components that remain under their own licenses. Nothing in these terms limits your rights under those licenses.

6. The caldrix.js package

The npm package @caldrix-ai/caldrix (caldrix.js), including the compiled browser host (WebAssembly and JavaScript glue) it embeds, is licensed separately under the Apache License, Version 2.0, by Jyothsna Muttineni acting for Caldrix GmbH (in formation), and is not part of the Software; on its registration, Caldrix GmbH becomes the Licensor of that package as of the Software. These terms, including section 4, neither restrict nor extend that license. Third-party components compiled into the host remain under their own licenses, listed in the package's THIRD_PARTY_NOTICES.md. That license grants no right to use the Caldrix name or marks beyond the attribution it requires. Models the package loads remain under their own licenses, as section 7 says of the Software. The caldrix binary and the other items that make up the Software remain under these terms.

7. Models

The Software downloads and runs model weights published by third parties, for example on Hugging Face. Those weights are not part of the Software. Their own licenses govern your use of them, and you are responsible for complying with them.

8. Data

The Software contacts Hugging Face (or the endpoint you set in HF_ENDPOINT) to download models, and the installer contacts GitHub to download release archives. The Software sends no data to the Licensor.

9. Ownership

The Software is licensed, not sold. The Licensor and its licensors keep all rights, title and interest in the Software, including all intellectual property rights. All rights not expressly granted are reserved.

10. No warranty

The Software is provided "as is" and "as available", without warranty of any kind, express or implied, including any warranty of merchantability, fitness for a particular purpose or non-infringement, to the extent permitted by law.

11. Limitation of liability

To the extent permitted by law, the Licensor is not liable for any damages arising from the Software or these terms, including lost profits, lost data and indirect or consequential damages. This limitation does not apply to liability for intent or gross negligence, or to any other liability that cannot be excluded or limited under Swiss law.

12. Termination

The license in section 2 ends automatically if you breach these terms. On termination you must stop using the Software and delete all copies. Sections 4 to 12 survive termination.

13. Changes to these terms

We may publish new versions of these terms at caldrix.ai/terms, each with its own version number and date. A new version applies to Software you download or use after its date.

14. Governing law and venue

These terms are governed by Swiss law, excluding its conflict-of-laws rules and the United Nations Convention on Contracts for the International Sale of Goods. The courts of Zug, Switzerland, have exclusive jurisdiction.
