Privacy policy

Last updated: 2026-09-09

The short version

Everything you type into a calculator on this site stays in your browser. It is not transmitted, not stored, and not visible to anyone operating the site. There is no user account, no login and no profile.

What the calculators do with your input

The calculations are performed by JavaScript running on your own device. The numbers, dates and times you enter never leave it. Closing or refreshing the page discards them.

Cookies

This build of the site sets no cookies of its own and uses no analytics.

If and when advertising is enabled, the advertising provider may set cookies or use similar technologies to serve and measure ads, including personalised ads where you have consented. At that point a consent banner will appear for visitors in regions that require one, and this policy will be updated to name the provider and link to their own policy. Until then, no third-party scripts run on this site.

Server logs

Like every website, the hosting provider records standard request information — IP address, browser user agent, the page requested and the time — for security and troubleshooting. This is handled by the host, not by the site itself, and is not linked to anything you type into a calculator.

Children

This site is a general-audience utility and is not directed at children under 13. No personal information is knowingly collected from anyone.

Where this site is operated from

The site is operated from Spain and is therefore subject to the EU General Data Protection Regulation. If you believe your data has been mishandled you may lodge a complaint with the Spanish data protection authority (Agencia Española de Protección de Datos) or with the supervisory authority in your own country.

Your rights

Because no personal data is collected by the site, there is nothing to request, correct or delete. If advertising cookies are added later, the consent banner will let you withdraw consent at any time.

Changes

Any material change to this policy will be reflected in the date above.

Who is responsible

This site is operated by Alexis Hidalgo-Gato, acting as the data controller. Contact: contact@calquly.com.
