2. Hosting and server log files
This website is hosted by Cloudflare Pages (Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA). Cloudflare is certified under the EU–US Data Privacy Framework. When the website is accessed, the hosting provider automatically records so-called server log files, including in particular:

These data are collected solely to ensure smooth operation and to improve the website, and are not merged with other data sources.

3. Local data storage (localStorage)
Your inputs (answers in the calculator) are stored exclusively locally in your browser (localStorage). No data are transmitted to our servers or third parties. You can delete these data at any time via the "Reset" function in the calculator or through your browser settings.
The legal basis is Art. 6(1)(f) GDPR (technically necessary storage to improve the user experience). No cookies are set.

Plausible Analytics sets no cookies and collects no personal data. In particular, IP addresses are neither stored nor passed on – they are used solely for temporary geolocation at the country level and are immediately discarded. There is no cross-site tracking and no profiling.
Only aggregated, anonymous usage data are collected, such as:
- Pages visited and time spent
- Country of origin (at country level)
