Privacy Policy

Overview

Welcome to elCalculador.com ("we," "our," or "us"). We are committed to protecting your privacy and operating a transparent, trustworthy platform. This Privacy Policy explains how we handle data when you visit and use our website.

elCalculador.com operates as a client-side calculation platform. We apply "Privacy by Design" principles — your financial inputs, health data, and calculation results are never transmitted to our servers. Everything happens in your browser.

1. No Registration Required

We do not require sign-up, registration, or account creation to use any of our 21 free calculators. You can use every tool on elCalculador.com completely anonymously. We never request, collect, or store credentials, full names, usernames, or passwords.

2. Client-Side Calculation Processing

All calculations — mortgage amortization, calorie estimation, VAT computation, clothing size conversion, and all others — are performed entirely within your local device's web browser using client-side JavaScript.

• Zero Server Transmission: Your financial inputs, health data, and calculation results are never transmitted over the internet to our servers.
• No Server Logs: We do not save, track, or intercept any values you enter into our calculators.
• Instant Volatility: The moment you close or refresh your browser tab, all entered data is permanently cleared from your device's temporary memory.

3. Cookie Usage and GDPR Compliance

In compliance with the EU General Data Protection Regulation (GDPR) and global privacy standards, we use cookies solely to improve your browsing experience and serve advertising that keeps our tools free.

When you first visit elCalculador.com, a cookie consent banner will appear. You can choose to accept or decline non-essential cookies. See our full Cookies Policy for complete details.

4. Google Analytics

We use Google Analytics to collect aggregated, anonymized traffic statistics — such as which calculators are used most, approximate geographic regions (country level), device types, and browser types. This data helps us improve tool performance and allocate resources effectively.

We have configured Google Analytics to automatically anonymize IP addresses. We do not pass any Personally Identifiable Information (PII) to Google through Analytics.

5. Google AdSense Advertising

We display advertisements provided by Google AdSense to keep all calculators free. Google uses the DART cookie to serve ads based on your visits to this and other sites on the internet. You may opt out of personalized advertising by visiting Google's Ad Settings.

6. Voluntary Contact Information

The only scenario where we collect personal information is if you choose to contact us via our contact form. In that case, we only receive your name, email address, and the content of your message. We use this solely to respond to your inquiry and do not use it for marketing or share it with third parties.

7. Security

All connections to elCalculador.com are protected using SSL/HTTPS encryption. Because your calculation data never leaves your device, the risk of data exposure from our systems is minimal by design.

8. Your GDPR Rights

If you are visiting from the European Economic Area (EEA), you retain all rights under the GDPR including the right to manage your cookie preferences. Since we do not store personal data profiles on our servers, there is no personal data to export, modify, or delete upon request beyond cookie preferences managed through your browser.

9. Changes to This Policy

We reserve the right to update this privacy policy to reflect changes to our platform or applicable law. Updates will be posted on this page with a revised "Last Updated" date.
