BriarKit

Terms

These terms describe the baseline conditions for using BriarKit, the site content, and any output created through the available tools.

Scope of the service

BriarKit provides web-based utility tools, reference content, and related site features for general informational and productivity use. The service is intended to help users complete common technical tasks more efficiently, but it is not sold as a managed professional service, custom consulting engagement, or guaranteed compliance solution.

Features may change over time, including the addition, removal, or revision of tools, limits, interface behavior, and supporting content. Continued use of the site means you accept that the service may evolve without preserving every prior workflow exactly as it existed.

Acceptable use

You may use the site for lawful, legitimate work consistent with its intended purpose. You may not use BriarKit to interfere with the service, abuse shared infrastructure, attempt unauthorized access, automate disruptive traffic, or process material in a way that violates applicable law or the rights of others.

You are also responsible for making sure that the content you paste, upload, transform, or generate through the site is material you have the right to handle. That includes ensuring that your use of customer data, secrets, proprietary text, or regulated material complies with your own contractual and policy obligations.

Output and user responsibility

Tool output is provided as a convenience, not as a substitute for human review. Even a simple transformation can have downstream consequences when it affects code, production configuration, encoded values, timestamps, signatures, or cryptographic material. You are responsible for validating any output before using it in a live, legal, financial, security-sensitive, or otherwise consequential context.

This applies whether the output is generated entirely in the browser or derived from your own inputs. The existence of a tool on the site should not be interpreted as a warranty that the output is complete, fit for your purpose, or appropriate for a regulated environment.

Availability and warranties

The service is provided on an as-is and as-available basis. BriarKit does not guarantee uninterrupted access, error-free behavior, permanent feature availability, or compatibility with every browser, device, file, payload, or edge case. Bugs, omissions, and temporary outages are possible.

To the maximum extent allowed by applicable law, no warranty is made regarding merchant ability, fitness for a particular purpose, or non-infringement. If you need contractual assurances, service levels, or formal support obligations, this public site should not be treated as providing them by default.

Limitation of liability

To the maximum extent permitted by law, BriarKit and its operators will not be liable for indirect, incidental, special, consequential, or business-interruption damages arising from or related to the use of the service. That includes losses associated with corrupted output, incorrect conversions, interrupted access, data handling decisions, or reliance on generated results.

If you use the site in a context where an error could create operational, contractual, or security exposure, you are expected to apply independent safeguards and review processes. The more critical the workflow, the less appropriate it is to rely on any public utility site without additional controls.
