Terms of use for this calculator website.
Northline Calculators Ltd. provides Northline Calculators as an informational calculator service. By using the site, you agree to use it lawfully and to understand that calculator results are guides, not guarantees.
Use of the service
The site is intended for general information, planning, and reference use. You agree not to misuse the service, interfere with the site, or attempt to extract or reproduce the site in a way that violates applicable law or these terms.
Calculator availability, page content, and supporting explanations may change as the library is updated and improved.
Reliance on calculator outputs
Calculator results are based on the formulas, assumptions, and values shown on each page. They are intended to help with understanding and estimation, not to replace professional judgement.
You are responsible for checking important figures independently before using them in financial, legal, medical, engineering, construction, or other high-stakes decisions.
Intellectual property
The site design, written content, structure, and original presentation of the calculators are protected by applicable intellectual property laws.
You may link to the site and use the calculators for personal or internal reference, but large-scale republication, scraping, or commercial reuse requires permission.
Liability and governing law
The service is provided on an as-available basis. To the fullest extent permitted by law, the site operator excludes liability for losses that result from relying on the service without appropriate independent review.
These terms are governed by the laws of England and Wales, unless a different legal framework is required by mandatory consumer protections.
