Terms of Use

You may use the public calculators for lawful personal, educational, and business purposes. You are responsible for the inputs you provide, how you interpret the result, and any decision you make from it.

You must not attempt to disrupt the service, bypass access controls, access another user's account or saved calculations, introduce malicious code, or use automated traffic in a way that materially impairs the service.

Calculators provide estimates from the inputs, formulas, assumptions, and cited sources shown on their pages. Results can be affected by rounding, changing laws or rates, incomplete inputs, local rules, and facts the calculator does not ask for.

Quanta does not provide legal, tax, medical, investment, engineering, or other professional advice. Verify high-stakes results with the applicable official source and a qualified professional.

You are responsible for safeguarding your sign-in credentials and for activity under your account. The free plan currently permits up to seven saved calculations. Quanta may restrict access needed to protect users, investigate abuse, or maintain the service.

You can remove saved calculations and delete your account through the dashboard. Account deletion is permanent after recent authentication succeeds.

The service is provided on an as-available basis. Quanta may correct formulas, update sources, change features, or temporarily interrupt access for maintenance or security. When a formula or source changes, previously saved outputs are not automatically recalculated.

Pro billing and the public calculator API are not enabled. A coming-soon label is not an offer to sell or a promise of a launch date.

To the extent permitted by applicable law, Quanta is not responsible for indirect or consequential loss arising from reliance on a calculator result or inability to access the service. Nothing in these terms excludes rights or liabilities that cannot legally be excluded.
