Privacy Policy

Last Updated: July 12, 2026

1. General Information

We take the protection of your personal data very seriously. This Privacy Policy explains what information we collect, how we process it, and your rights under the General Data Protection Regulation (GDPR).

2. Local Storage Calculations

Our date calculator runs 100% locally in your web browser. Any date parameters, start or end ranges, and calculation outcomes you input are processed directly on your computer. We do not transmit, collect, or store your inputs on our servers.

3. Log Files and Hosting

When you access our site, our hosting partner (Vercel) automatically collects generic server log files (IP address, browser user-agent, date/time, page visited). This collection is technically necessary to display the website correctly and maintain stability and security (legal basis: Art. 6 para. 1 lit. f GDPR).

4. Cookies

We use simple functional cookies (such as storing your dark mode theme preference). If we introduce optional analytics or ad tracking tools in the future, we will collect your explicit consent beforehand through a cookie consent manager.

5. Your Rights

You have the right to request access to, rectification of, or erasure of your personal log data held by us, as well as the right to restrict or object to its processing. You may file complaints directly with supervisory authorities.
