Who is responsible

Roger Killer, Switzerland, is responsible for this website and its data processing. For privacy questions or requests, you can contact me through the LinkedIn or Bluesky profiles in the footer.

Hosting and server logs

This website is hosted on infrastructure provided by Hetzner Online GmbH in Germany. When you access the site, your browser and the hosting infrastructure exchange technical request data. This can include your IP address, the date and time, the requested page, the referring page, and browser or operating-system information.

This data is processed to deliver the website, maintain reliable operation, and investigate misuse or security incidents. It is not used for visitor analytics or profiling and is retained only for as long as operational or security purposes require it.

Local browser storage

The site stores your chosen light or dark colour mode in your browser under the key therkiller-color-mode . This setting contains no unique identifier and is not used for tracking.

Nuxt Content may also store a compressed cache of published site content and checksums under keys beginning with content_ . This cache contains content from the website, not information you provide, and is not used to identify or track you.

Both types of storage remain on your device and can be removed by clearing the site data in your browser.

The site does not set analytics or advertising cookies.

External links

The website contains ordinary links to external services such as GitHub, Bluesky, and LinkedIn. No content from these services is embedded. Data is sent to an external service only after you follow its link, and the service's own privacy terms then apply.

Your rights

Subject to applicable Swiss data-protection law, you may request information about personal data concerning you and ask for incorrect data to be corrected or data to be deleted. You may also object to particular processing where the law provides for it.

Changes to this notice

This notice will be updated if the website starts using new services or changes how personal data is processed. The date at the top shows the latest revision.
