Terms of Use

Last updated: October 1, 2026

These terms govern your use of varyvia.com. By using Varyvia, you agree to use the site lawfully and responsibly.

Informational tools, not professional advice

Varyvia calculators provide general informational estimates. Results are not legal, tax, medical, financial, accounting or other professional advice. Important decisions should be checked against authoritative sources or an appropriately qualified professional.

Accuracy and assumptions

We work to test our formulas and explain important assumptions, but inputs, rounding, local rules and real-world conditions can affect results. You are responsible for checking that your inputs, units and assumptions fit your situation before relying on a result.

Permitted use

You may use Varyvia for personal, educational and ordinary business calculations. You may not interfere with the site, bypass security controls, send malicious traffic, scrape the service in a way that materially harms its operation, or use the site for unlawful activity.

Intellectual property

Varyvia's branding, original interface, written content and original site materials are protected by applicable intellectual-property laws. Mathematical facts and formulas themselves are not claimed as proprietary merely because they appear in a calculator.

Third-party services and advertising

The site may use or link to third-party services, including hosting, analytics, consent-management and advertising providers. Their services are governed by their own terms and policies. An advertisement does not mean Varyvia endorses the advertised product or service.

Availability

We may update, add, remove or temporarily suspend calculators or site features. We do not promise uninterrupted or error-free availability.

Limitation

To the extent permitted by applicable law, Varyvia is provided on an “as available” basis and we are not responsible for losses caused solely by reliance on an estimate when the result should reasonably have been independently verified. Nothing in these terms excludes rights or liabilities that cannot legally be excluded.

Changes

We may revise these terms as the service changes. The revision date above will be updated when material changes are published.
