Where this site runs
On a private server in a private household in Germany. There is no hosting provider and no processor that data would be passed to.
What happens when you visit
The web server in front of this site keeps no access log; IP addresses are not stored. There are no cookies, no tracking, no analytics, and no third-party fonts or scripts — every file comes from this same server.
Your browser only stores your own settings (chosen language, light or dark theme, last selected time spans). That lives in your browser's local storage, never leaves your device and can be cleared there at any time.
The data sources never see you
The server fetches every measurement from the sources on a fixed schedule and caches it. Your browser never talks to SMARD, Energy-Charts or the frequency sources, so none of them learns your IP address. The sources are listed under Sources & licences.
Donation button
The donation button is an ordinary link, not an embedded payment widget. Only when you click it do you leave this site, and PayPal's privacy policy applies (PayPal (Europe) S.à r.l. et Cie, S.C.A., Luxembourg). Nothing is transmitted there before that.
Legal basis
Where personal data is processed at all — technically the IP address during transmission, which is not stored — the legal basis is Art. 6 (1) (f) GDPR: the legitimate interest in operating the site.
Your rights
Access, rectification, erasure, restriction, portability and objection (Art. 15–21 GDPR) via the address above. As nothing is stored, there is usually nothing to hand over or delete.
You may lodge a complaint with the supervisory authority: Saxon Data Protection Commissioner, Devrientstraße 5, 01067 Dresden, Germany.
