Privacy Policy
Our Privacy Principle
Calculator Converter Tool is built around a simple idea: you should not need to share personal data to use a calculator. The numbers you enter into a calculator are processed entirely in your own web browser and are never sent to our servers.
Information We Do Not Collect
We do not require you to create an account, and we do not store the height, weight, age, measurements or any other values you enter into a calculator. Closing or refreshing the page clears those values from your browser.
Technical and Log Data
Like most websites, standard server logs may automatically collect limited technical information such as your browser type, referring page and the pages you visit, solely to keep the site secure and reliable. This data is not linked to the values you enter into calculators.
Cookies and Local Storage
The site does not require advertising or tracking cookies to use the calculators. Your light/dark theme preference may be stored locally in your browser so it is remembered on your next visit; this stays on your device and is not used to track you.
Third-Party Links
Each calculator links to one external reference for further reading. Those sites have their own privacy policies, and we are not responsible for their practices.
Changes to This Policy
We may update this policy from time to time. The date at the top shows when it was last revised.
Not Medical Advice
Nothing on this site is medical advice. Consult a qualified professional for personal health decisions.
