Privacy policy

Note: This is a translation for information purposes. The German version is legally binding: Datenschutzerklärung.

Placeholder: The privacy policy still has to be completed (controller, contact details, rights of data subjects).

Technical set-up of this website

  • No tracking, no analytics tools. Cookies are used only for signing in and for the language setting (see below).
  • No external resources: fonts, scripts and graphics are loaded exclusively from this server.
  • Server logs store IP addresses only in truncated (anonymised) form.
  • All data is transmitted in encrypted form (HTTPS).

User account and sign-in (passkeys)

  • A free account is required for the dashboard. We store: your email address (as username, confirmed via a link), the public part of your passkey or – if you set a password – only an irreversible hash (scrypt) of the password, the times of registration, last sign-in and last password change, and failed password sign-in attempts (per email address, deleted after 24 hours). The password itself is never stored; the secret part of the passkey never leaves your device.
  • We send to your email address only confirmation links that you request yourself (registration, additional device), plus a reminder before an unused passkey is deleted. Emails are sent via our own mail server and the delivery service Oracle Cloud Infrastructure Email Delivery (Frankfurt data centre).
  • Cookies: __Host-sitzung (sign-in, 30 days, technically necessary), __Host-vorgang (sign-in process, 5 minutes) and angemeldet (shows “Account” instead of “Sign in” in the header). No disclosure to third parties.
  • Passkeys you have not used to sign in for 12 months are deleted automatically. You will receive a reminder by email about 30 days beforehand. Your account remains in place; you can create a new passkey at any time via a confirmation link sent to your email address.
  • You can delete your account yourself at any time under Account; all data is removed immediately.

Language setting (German/English)

  • On your first visit, we select the language automatically: based on your browser’s language setting and, if this is not conclusive, on the country to which your IP address is assigned.
  • The country lookup takes place exclusively on our own server using the “IP to Country Lite” database by DB-IP (licence CC BY 4.0). Your IP address is neither transmitted to third parties nor stored for this purpose.
  • Cookie: sprache (value de or en, 1 year, technically necessary) stores only the language you have chosen once you change it using the language switch. No disclosure to third parties.
  • IP geolocation by DB-IP
