Privacy Policy

The most important point first: what you type into the calculators stays in your browser.

Last updated: September 29, 2026

This privacy policy explains how ILION PROJECT SL handles information when you visit this website. Please also read the Terms of Use and the Cookie Policy.

Who is responsible for this website

ILION PROJECT SL is a Spanish company and acts as the data controller for this website. The European General Data Protection Regulation (GDPR) applies to the company even when visitors are located in the United States.

What you type into the calculators

It is not collected, not transmitted and not stored. All calculators on this site run entirely in your browser. The measurements and values you enter stay on your device and disappear when you close the page.

What this website does not have

This website has no user accounts, no forms, no comments and no blog. Because of that, it does not collect the information that those features usually collect.

Information we may receive

Analytics and your choice

When Google Analytics is enabled, it starts with all analytics cookies denied. Nothing is stored on your device for analytics until you press Accept in our cookie notice. You can also press Reject, or press Configure to choose by purpose. Rejecting is as easy as accepting. Your choice is saved in a technical cookie of our own called cs24-analytics, which lasts 6 months. You can change your choice at any time with the Configure cookies button in the footer. Google Ireland Limited processes the analytics data on our behalf.

If you reject analytics cookies, measurement may continue without cookies. In that case, signals are sent that do not store or read anything on your device and do not allow you to be followed between visits.

Advertising and Google

This site may show ads served by Google. Google and other third-party vendors may use cookies, web beacons and IP addresses to serve ads and to measure how they perform. This processing is governed by Google's policies. For visitors in the European Economic Area and the United Kingdom, a separate Google notice asks for your choice about advertising cookies.

You can read how Google uses data when you use sites or apps of its partners and manage your ad preferences in Google Ad Settings.

Our legal bases (visitors in the EU, EEA and UK)

We process information on the following bases:

Who processes information for us

The website runs behind Cloudflare, which acts as a content delivery network and proxy, and on a server hosted by OVH in France. Google provides the analytics and advertising services described above. These providers process information as needed to deliver those services.

Your privacy rights

Visitors in the EU, EEA and UK. You have the right to ask whether we process personal information about you. You may also ask us to give you access to it, correct it, delete it, restrict its processing, or send it to you in a portable format. You may object to processing and withdraw your consent at any time. You also have the right to lodge a complaint with a data protection supervisory authority. In Spain, that authority is the Spanish Data Protection Agency (AEPD).

Residents of California and other U.S. states. Depending on where you live, applicable privacy laws may give you rights to know what personal information a business collects about you, to access, correct or delete it, and to opt out of the sale or sharing of personal information. We do not sell personal information in exchange for money. Advertising provided by Google may be considered “sharing” of personal information under some state privacy laws. You can limit personalized advertising in Google Ad Settings and through the cookie settings on this site. We will not treat you differently for exercising your privacy rights.

To exercise any of these rights, write to [email protected]. If we have doubts about your identity, we may ask you to confirm it before we act on your request.

Security

ILION PROJECT SL applies security measures appropriate to the level of risk to protect information against loss, misuse and unauthorized access. No system on the internet can be guaranteed to be completely secure. If ILION PROJECT SL determines that personal information it processes has been exposed by a security breach, it will act as required by the applicable data protection laws.

Changes to this policy

ILION PROJECT SL may update this policy to reflect changes in the law or in industry practice. Any changes will be announced on this page, and the date at the top will show when it was last updated.

Questions

If you need more information about how your information is handled, write to [email protected] or visit the contact page.

We use our own technical cookies and, if you allow it, Google Analytics cookies to see which calculators are used most. Press “Accept” to allow analytics, “Reject” to refuse them or “Configure” to choose. If you don’t accept, we still measure visits without cookies and with approximate figures. You can change your mind at any time from the footer. More details in the cookie policy.
