Terms of use

Updated October 6, 2026

Purpose and scope

Cup & Ratio provides educational material about coffee brewing and water. The guides and tools depend on stated assumptions and cannot assess every reader’s product, circumstances or equipment.

Using the material

You may read, link to and use the information for personal learning. Respect applicable rights in original text, illustrations and third-party material. External references remain the work of their respective owners. Their inclusion does not imply permission to republish them.

Accuracy and changes

Errors, outdated references and missing context are possible. The preview’s unresolved verification limits are stated in the editorial policy. Check primary sources and manufacturer instructions before acting on a product-specific procedure. We may revise, correct or remove material.

Tools and external links

Calculator output is an estimate based on the input and model. A reference table is not a product certification. External sites have their own terms and may change independently. You are responsible for assessing whether a method applies to your circumstances.

Acceptable use

Do not interfere with access, attempt to misuse the site or present altered material as an official publication from Cup & Ratio. Reasonable linking and quotation should preserve attribution and context.

Limitations and applicable rights

Content is provided for education without a promise of a particular outcome. Nothing in these terms is intended to exclude rights or responsibilities that cannot be excluded under applicable law. The operating entity, jurisdiction and any necessary local terms remain to be confirmed before public launch.

Questions and revisions

See publisher contact information, the privacy policy and the subject-specific disclaimer. The revision date above identifies this version.
