Our privacy commitment
Calculator inputs stay in your browser. We use anonymous analytics and advertising cookies to improve and support the site, and you can control those preferences through your browser or Google privacy settings.
1. Information We Collect
Anonymous technical data only - no personally identifiable information
We automatically collect limited, anonymous technical data when you visit our website, including browser type and version, pages visited on our website and time spent on them, approximate geographic location (country/city level only, not precise), device type and screen resolution, referring URL (the page that directed you to our site), and IP address (anonymized).
This data is collected automatically via Google Analytics and is used only to understand how visitors use our website and to improve our service.
2. How We Use the Information
Anonymous data used for website improvement and relevant advertising
We do not sell, rent, or share your personal data with third parties for their own marketing purposes.
3. Google Analytics
Web analytics with IP anonymization for privacy protection
We have enabled IP Anonymization in Google Analytics. This means your IP address is truncated by Google before it is stored, so it cannot be used to identify you personally.
Google may process this data in accordance with its own privacy policy: https://policies.google.com/privacy
5. Google AdSense
Advertisement service with IAB compliance and data protection
This information is used to provide advertisements about products and services that may be of interest to you. It does not include your name, address, email address, or telephone number.
Google AdSense is compliant with the IAB Europe Transparency and Consent Framework. For more information on how Google uses data collected through its advertising services, visit: https://policies.google.com/technologies/ads

If you are a parent or guardian and believe your child has provided personal information to us, please contact us immediately and we will take prompt action to address it.
8. GDPR – Rights of Users in the European Union
European users' rights under GDPR with clear data processing basis
Since we collect no personally identifiable information, most of these rights are satisfied by default. For data processed by Google Analytics or Google AdSense, you may exercise your rights directly with Google via: https://myaccount.google.com/privacy
Our legal basis for processing anonymous analytics data is our legitimate interest in improving our website. For advertising cookies, our legal basis is your consent, which you provide through our cookie consent banner.
