Privacy policy.

What we do not collect

• Values typed into calculators, simulators and tools.
• Text, lists and passwords generated or processed in the tools.
• Your name, email, Social Security number or any account details: the site never asks for them.

What is collected

Like any website, the server that delivers the pages logs technical access data, such as IP address and browser, for security and performance.

We measure audience with Google Analytics 4, loaded through Google Tag Manager. It records pages visited, device type, traffic source and usage actions, such as "used the calculator", "copied the result" or "opened an FAQ question". Events say only which tool was used and never the values typed. We use Google's consent configuration with advertising and personalization turned off.

Google Analytics stores an identifier in a browser cookie to recognize repeat visits, and Google handles that data under its own policy. To opt out, use your browser's option to disable Google Analytics or block third-party cookies.

Ads

Calterix does not show ads or sell data. If that changes, this page will be updated first, naming the companies involved and explaining how to opt out.

Storage on your device

The calculator history stays in browser memory while the page is open. Links with values in the URL are created by you when you copy the address.

Your rights

Under applicable privacy laws, you can ask for access to, correction of or deletion of any personal data we may hold. The contact channel will be listed on the contact page.
