💻Client-Side Computation (Privacy by Design)

Using our clean energy calculators (Solar PV, Battery Storage, Grid Independence, Heat Pumps, Heating Comparison, EV Charging) does not require submitting personal identifiable information.

🌐Web Hosting & Technical Server Logs

Our website is hosted on dedicated server infrastructure located within the European Union. Whenever you visit this website, the web server automatically records essential technical data in server access logs:

Browser model, user-agent, and build version
Operating system architecture
Referrer URL (previously visited page)
Hostname or IP address of the accessing client
Date and timestamp of the server request

This data is strictly necessary to maintain system stability, ensure web security, and defend against malicious cyber attacks. The processing is based on statutory legitimate interests (Art. 6(1)(f) GDPR / UK GDPR). Server logs are never linked with external data sources.

💾Local Browser Storage (localStorage)

KalkImmo does not deploy tracking cookies or third-party marketing beacons. To improve usability, we utilize browser local storage (localStorage) strictly to retain your selected city, state filter, or calculator view for subsequent sessions. This state remains isolated on your device and is never transmitted to our servers.
