Privacy policy

Last updated: August 28, 2026.

Who is responsible

This site is operated by Fernando Jonás Mata López, based in León (Spain). You can reach us by email at info@calculoteca.com.

What data is collected

The calculators on this site run entirely inside your own browser. Any amount, term, rate, weight, height, or other figure you type is never sent to any server, is never stored in any database, and is not accessible to the site owner or to anyone else. It disappears the moment you close the tab.

There is no user registration and no personal data is requested anywhere on the site.

Hosting technical data

Like any website, our hosting provider logs technical request data (IP address, date and time, browser, and page requested) to keep the service running and secure. These logs are managed by our hosting provider, Hostinger International Ltd., and kept for whatever period they set.

Cookies

This site does not set its own analytics or tracking cookies.

If third-party advertising is enabled (for example Google AdSense), those providers may set cookies to show ads and measure their performance. Where required, a consent banner is shown first, letting you accept or decline. This section will be updated with the specific cookies used and their purpose.

You can block or delete cookies at any time from your browser settings.

Your choices

Since no personal data is collected through the calculators, there is little to request, correct, or delete. If you've written to us by email and want that message removed, write to info@calculoteca.com and we'll delete it.

Changes to this policy

This policy may be updated to reflect legal or site changes. The date of the latest update appears at the top of this document.
