§ 1 What these terms cover
Software and website
These terms govern your use of the Halton Meter software (the daemon and any bundled components) and the haltonmeter.com website. By installing the software or using the website you agree to these terms.
§ 2 License
Polyform Perimeter 1.0.0
The Halton Meter daemon is licensed under the Polyform Perimeter License 1.0.0. A copy is included with the software.
Permitted
- Install, run, and modify the software for your own internal cost tracking and attribution.
- Use it in commercial settings — at an agency, within a company, or on client work.
Not permitted
- Building or operating a competing product or service — meaning any product whose primary purpose is LLM API proxying, usage metering, cost attribution, or similar capabilities offered to third parties.
The full Polyform Perimeter License text governs; the above summary is for convenience only and does not modify the license.
§ 3 No warranty
As is, without warranty
The software is provided as is, without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose, and non-infringement.
Halton Meter is in active development. Cost calculations depend on pricing data that providers change without notice. We make reasonable efforts to keep pricing current, but we cannot guarantee that computed costs will match your provider's billing at all times. Do not rely on Halton Meter as your sole source of billing truth without independent reconciliation.
§ 4 Limitation of liability
Capped at £50 GBP
To the fullest extent permitted by applicable law, Halton Labs and its operator shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or related to your use of the software or these terms, even if advised of the possibility of such damages.
Our total liability for direct damages shall not exceed the greater of (a) the amount you paid for the software in the twelve months preceding the claim, or (b) £50 GBP.
§ 5 Acceptable use
What you may not do
You may not use the software or website to:
- Violate any applicable law or regulation.
- Interfere with or circumvent the security measures of any LLM provider or third-party service.
- Attempt to reverse-engineer the software beyond what the Polyform Perimeter License permits.
§ 6 Third-party services
Provider terms apply downstream
The software routes traffic to third-party LLM APIs (Anthropic, OpenAI, Google, xAI/Grok, and others). Your use of those services is governed by each provider's own terms and policies. Halton Labs is not responsible for the availability, pricing, or behaviour of any third-party API.
§ 7 Changes to the software and terms
Material changes get a date bump
We may update the software and these terms at any time. Material changes to these terms will be noted in the product changelog and reflected in the effective date above. Continued use after a material change constitutes acceptance.
§ 8 Governing law
England and Wales
These terms are governed by the laws of England and Wales. Any disputes shall be subject to the exclusive jurisdiction of the courts of England and Wales.
