Frequently Asked Questions
Can I link from my website to a calculator on alltoolscalculator.com?
Yes, please feel free to link to any page on alltoolscalculator.com.
Are the calculator results accurate?
We use industry-standard formulas verified against trusted sources. However, results are estimates and should not be the sole basis for important decisions. For high-stakes decisions (financial, medical, legal), always consult a qualified professional. See our Disclaimer for details.
Do you save the data I enter into calculators?
No. Calculations happen entirely in your browser, and the values you enter are not stored on our servers.
Do you have an API for the calculators?
We do not currently offer a public API. If you have a specific use case, please contact us at contact@alltoolscalculator.com and we will consider it.
How do I delete my data?
