Our Commitment to Your Privacy

At Kostenloser BMI-Rechner, we take your privacy seriously. This policy explains what information we collect (spoiler: very little), how we use it, und what rights you have.

The short version: We don't collect, store, or sell your personal information. Your BMI calculations happen entirely in your browser. We're not in the data collection business - we're in the health information business.

Information We Don't Collect

Let's start with what we DON'T do:

• We don't collect your BMI calculations. When you use our calculator, all the math happens in your browser. Your height, weight, und BMI results never get sent to our servers.
• We don't require accounts or logins. No usernames, passwords, or personal profiles. You can use our calculators completely anonymously.
• We don't ask for your name, email, or contact information unless you choose to Kontaktieren Sie uns directly.
• We don't use tracking pixels or fingerprinting. We respect your privacy und don't try to follow you around the internet.
• We don't sell your data. There's nothing to sell because we don't collect it in the first place.

Information We Do Collect

We collect minimal technical information to keep the site running und improve it:

Basic Website Analytics

We use standard web analytics (similar to most websites) to understand how people use our site. This includes:

• Pages you visit on our site
• How long you spend on each page
• What device und browser you're using
• Approximate geographic location (country/city level, not your exact address)
• How you found our site (search engine, direct visit, link from another site)

This data is aggregated und anonymized. We can't identify you as an individual from this information.

Cookies

We use minimal cookies to remember your preferences (like which language you chose or if you prefer metric vs imperial units). These cookies store settings locally on your device und don't contain any personal information about you.

You can disable cookies in your browser settings, but some features might not work as smoothly.

Server Logs

Our web server automatically logs basic information like your IP address, the pages you visit, und when you visit them. This is standard practice for all websites und helps us troubleshoot technical issues. These logs are kept for a limited time und aren't used to track or identify you.

How We Use Information

The limited information we collect is used solely to:

• Keep the website running smoothly und fix technical problems
• Understand which pages und features are most useful so we can improve them
• See how people find our site so we can reach more people who need it
• Detect und prevent abuse or security issues

We do NOT use this information to:

• Build profiles about individual users
• Serve personalized advertisements
• Sell or share with third parties
• Kontakt you (unless you Kontaktieren Sie uns first)

Third-Party Services

We may use third-party services to help operate our website:

Analytics Services

We may use privacy-focused analytics services to understand how our site is used. Any service we use is chosen specifically for its respect of user privacy.

Hosting Provider

Our website is hosted by a third-party hosting provider, which may collect standard server log information. We choose hosts that respect user privacy und comply with data protection regulations.

No Advertising Networks

We don't use Google AdSense or similar advertising networks that track you across websites. If we do add advertisements in the future, we'll update this policy und only use privacy-respecting ad services.

How Your BMI Calculator Works (Technically)

This is important to understand: Our BMI calculator runs entirely using JavaScript in your web browser. Here's what happens when you use it:

1. You enter your height und weight in your browser
2. JavaScript code (running on YOUR device) performs the calculation
3. The result is displayed to you immediately
4. That's it - nothing gets sent to our servers

We literally have no way to see what you entered or what your BMI is. It all happens on your device, privately.

Kontakt Information

If you Kontaktieren Sie uns via email, we'll use your email address only to respond to your message. We won't add you to mailing lists or share your contact information with anyone else. After we've resolved your inquiry, we may keep your email for record-keeping purposes, but we won't use it to contact you again unless you reach out to us.

Children's Privacy

Our website can be used by anyone, including children under 13, to calculate BMI. We don't knowingly collect personal information from anyone, including children. Parents can feel confident letting their kids use our calculators because there's no data collection, no account creation, und no information sharing.

International Users

Our website is accessible worldwide. We don't treat users differently based on location - everyone gets the same privacy protection. If you're accessing our site from the European Union, GDPR applies. If you're in California, CCPA applies. We're committed to following the strictest privacy laws regardless of where you live.

Since we don't collect personal data, there's nothing for us to share, sell, or process, which makes compliance pretty straightforward!

Your Rights

Even though we don't collect much information, you still have rights:

• Right to know: You can ask what information we have about you (which is basically nothing beyond aggregate analytics).
• Right to access: You can request to see any data we might have related to you.
• Right to delete: You can ask us to delete any information we might have about you.
• Right to opt-out: You can disable cookies und use privacy-protecting browser extensions.

To exercise these rights, Kontaktieren Sie uns at contact@freeonlinebmicalculator.org

Data Security

We protect the limited data we collect using industry-standard security practices:

• HTTPS encryption for all pages (that's the lock icon in your browser)
• Secure hosting infrastructure with regular security updates
• Access controls limiting who can view our analytics und server logs
• Regular backups to prevent data loss

That said, no website can be 100% secure. But since we don't collect sensitive personal information, there's not much to compromise.

Changes to This Policy

We may update this privacy policy occasionally to reflect changes in our practices or legal requirements. When we make significant changes, we'll update the "Last updated" date at the top of this page.

We won't make changes that reduce your privacy protections without prominently notifying you first. If we ever decide to start collecting more information, we'll be completely transparent about it und give you clear options to opt out.

Questions?

If you have questions about this privacy policy or how we handle information, please Kontaktieren Sie uns. We're happy to explain our practices in more detail or address any concerns you might have.

The Bottom Line

We built this site to provide a useful, free tool - not to collect data about you. Your privacy matters to us because we're users of the internet too, und we know how annoying it is when websites track everything you do.

Use our calculators with confidence. Your health information stays private und on your device, where it belongs.
