Privacy policy

This website uses no advertising cookies and loads no content from third parties. Statistics (Google Analytics) are only used if you explicitly agree. Personal data is only processed to the extent described below.

1. Controller

2. Hosting and server log files

This website is operated technically by lightsignalmedia.group, Cologne, Germany, on servers in Germany. When you visit the website, the server automatically stores the information your browser transmits (IP address, date and time, page requested, referrer, browser and operating system) solely to operate the website securely and reliably. Log files are deleted after 45 days at the latest. Legal basis: Art. 6 (1) (f) GDPR.

3. Contact form

If you send a message via the contact form, your name, e-mail address and message are sent by e-mail via the web server to the controller. They are used only to answer your message and are not passed on to third parties. The data is deleted once your request has been dealt with, unless statutory retention obligations apply. Legal basis: Art. 6 (1) (f) GDPR and, if your message concerns a contractual matter, Art. 6 (1) (b) GDPR.

4. Cookies, local storage and consent

On your first visit a notice asks whether you allow statistics (Google Analytics). Your choice is stored locally in your browser (localStorage) and does not leave your device. You can change or withdraw it at any time via “Cookie settings” in the footer. The content management system may set a technically necessary session cookie, which is deleted when you close your browser. If you switch between light and dark mode, your choice is also stored only in your browser.

5. Google Analytics (only with consent)

If you agree to statistics, this website uses Google Analytics 4 by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, to evaluate how the website is used, for example which articles are read and how often a link to an original publication is opened. Google Analytics uses cookies; data is transferred to Google servers, possibly in the USA. IP addresses are shortened. Legal basis is solely your consent (Art. 6 (1) (a) GDPR), which you can withdraw at any time via “Cookie settings”. Without your consent Google Analytics is not loaded. Measurement ID: G-SDKTNDBQT8.

6. Fonts, images and external links

All fonts, icons, images and the formula typesetting (KaTeX) are loaded from this website's own server; no content is loaded from Google Fonts or other external providers. Articles link to the original publications on the websites of journals and publishers. These pages are only loaded when you click such a link; the privacy policy of the respective provider then applies.

7. Your rights

You have the right of access, rectification, erasure, restriction of processing, data portability and objection (Art. 15 to 21 GDPR). To exercise these rights, use the contact form or write to the e-mail address above. You also have the right to lodge a complaint with a supervisory authority; in the Netherlands this is the Autoriteit Persoonsgegevens, Postbus 93374, 2509 AJ Den Haag.

8. Changes

This policy is updated when the law or the technology of the website changes.
