Hosting and Content Delivery

This website is hosted and delivered through Cloudflare Pages and Cloudflare's content delivery network. When you access the site, Cloudflare may process personal data such as your IP address, request metadata, browser information, and server log data in order to deliver the website, maintain stability, and protect against abuse.

The processing is based on our legitimate interest in providing a secure and reliable website under Article 6(1)(f) GDPR.

Email Contact

If you contact me by email, your message, email address, and any other information you provide will be processed in order to handle your request. The processing is based on Article 6(1)(b) GDPR if your request relates to a contractual or pre-contractual matter, and otherwise on Article 6(1)(f) GDPR based on the legitimate interest in responding to enquiries.

The data is retained for as long as necessary to process your request and to comply with any legal retention obligations.

Local Storage for Theme Preference

This website stores your selected theme preference in your browser's local storage so the site can remember whether you prefer light, dark, or automatic theme mode. This information stays on your device and is used only to provide the requested display setting.

Third-Party Embedded Content

Some posts include embedded content from third-party providers. On pages where such content is present, these providers may receive your IP address, browser information, and other technical data when the page is loaded.

The embedded providers currently used on this site are:

X / Twitter for embedded posts
YouTube for embedded videos
GitHub Gist for embedded code snippets

These embeds are used to present external content directly in relevant articles. The processing is based on Article 6(1)(f) GDPR, reflecting the legitimate interest in a functional and useful presentation of the content. Data processing by those providers takes place under their own responsibility.
