Terms of Use

Last updated: August 29, 2026

Purpose

Zelvaniq provides free calculators, converters, comparison tools and educational explanations for general informational use. The site does not create a professional-client relationship and does not provide financial, investment, lending, insurance, tax, legal, medical, engineering or other regulated professional advice.

Accuracy and assumptions

We aim to use stated formulas and reasonable computational methods, but results can differ from real outcomes because of rounding, incomplete inputs, local rules, changing rates, product terms, taxes, fees, measurement error or simplified assumptions. Verify important decisions using official documents or a qualified professional.

User responsibility

You are responsible for checking that your inputs, units and assumptions match your situation. Do not rely on a calculator as the sole basis for a high-stakes decision.

External data and links

Some tools may use public third-party data or link to external resources. Availability, accuracy and terms of those services can change independently of Zelvaniq.

Changes

Calculators, formulas, explanations and these terms may be revised as the site is improved. Continued use of the site means you accept the current version.
