These terms apply to BrewRatioNest and its home coffee brewing calculator, guides and related pages. Use the site lawfully and read the limits relevant to each calculation.
Educational calculations
A mass-ratio planner, not a measurement of extraction, caffeine, water chemistry or taste. The defaults are examples rather than a universal brewing prescription.
Results depend on the values you supply and the stated method. A result is not a binding quote, product certification, professional assessment or guarantee of a future outcome. Examples demonstrate arithmetic. You are responsible for selecting an appropriate input source and checking requirements that apply to your real situation.
Inputs and model boundaries
Water stays in the grounds and filter, and some can be lost during brewing. The tool does not subtract an assumed retention factor. Weigh the finished drink separately if yield matters to your record. Do not increase the coffee dose simply because the collected cup weighs less than the water poured.
Do not force a model to represent a different question by changing unrelated fields. The calculator page explains units, method and examples, and the journal guide explains the comparison record.
Reasonable use and content rights
Do not disrupt the service, attempt unauthorized access, submit malicious messages or use material in a way that infringes rights. Avoid sharing credentials and private records. Rights in third-party material remain with their owners. Contact the operator with the affected URL for a content-rights concern.
External services and advertising
External websites and advertisements, if displayed, are controlled by their operators and have their own terms. A link or ad does not mean BrewRatioNest endorses a provider or guarantees a claim. Availability and external content can change.
Changes and corrections
Software and explanations may be corrected or updated. Use the contact page to report a reproducible issue. Nothing in these terms removes rights that cannot lawfully be limited. The privacy policy describes calculator inputs, page visits and messages.
