Legal

Terms of Use

Last updated 8 June 2026

These terms govern your use of the provenrail.com website and the open-source Provenrail software. By using either, you agree to them. If you do not agree, do not use them.

The software and its licenses

Provenrail is open-source. The client, SDK, verifier, and specification are provided under the MIT License. The server is provided under the GNU AGPL-3.0-or-later. A separate commercial license is available for organizations that prefer not to be bound by the AGPL. The applicable open-source license text, not these terms, governs your rights to use, modify, and redistribute the code. See licensing.

What Provenrail is, and is not

Provenrail is evidence tooling. It makes the records that reach a sink tamper-evident and independently verifiable. It is not legal advice and not a guarantee of compliance. It cannot prove completeness: an agent that never calls the SDK will not appear in the record. References to regulatory frameworks describe how the technical controls map to those frameworks as supporting evidence; they are not certifications. See the disclaimer.

No warranty

The software and the website are provided "as is", without warranty of any kind, to the fullest extent permitted by law. We do not warrant that they will be uninterrupted, error-free, or fit for a particular purpose. You are responsible for how you deploy and rely on them.

Limitation of liability

To the fullest extent permitted by law, we are not liable for any indirect, incidental, special, or consequential damages, or for loss of data, profits, or goodwill, arising from your use of the software or website. Nothing in these terms limits liability that cannot be limited under applicable law.

Acceptable use of the website

Do not attempt to disrupt, overload, probe, or gain unauthorized access to the website or its infrastructure. The hosted verifier is rate-limited and size-capped; do not attempt to circumvent those limits.

Trademarks

"Provenrail" and the Provenrail logo are marks of the project. The open-source licenses grant rights to the code, not to the marks.

Changes

We may update these terms. Material changes will be reflected in the date above. Continued use after a change means you accept the updated terms.
