This is a personal site. It sells nothing, runs no advertising, carries no affiliate links and takes no payments. Contact is by email only, so no postal address is published.

What this site collects

Nothing. There are no cookies, no analytics, no tracking pixels, no third-party embeds and no contact form. Fonts and images are served from this domain, not from Google Fonts or any other third party.

You can confirm this yourself: open your browser's network tab on any page here. Every request goes to xraynbow.com.

Hosting

The site is static and hosted on Cloudflare Pages (Cloudflare, Inc., with EU processing via Cloudflare Germany GmbH). Cloudflare processes standard server log data — IP address, timestamp, requested URL, user agent — for delivery, caching and abuse prevention. That is the host's processing, not mine; I do not read, export or store those logs.

If you email me

Your message and address land in my mailbox and are used only to reply. Nothing is added to a list, shared, or sold. Ask me to delete a thread and I will.

Links to other sites

Outbound links — LinkedIn, PERGOLUX systems, the Meta Ad Library — go to services with their own terms and privacy policies. I am not responsible for their content and have no control over what they collect once you arrive.

Your rights

Under GDPR you can ask what data I hold about you, ask for it to be corrected or deleted, and complain to a supervisory authority. For this site the honest answer to the first question is: whatever you sent me by email, and nothing else.

Email [email protected] and I will answer.

Content

Everything here describes my own work. Employer names, systems and figures are stated as they were at the time of writing and are not a statement on behalf of any employer. Text and images are mine unless credited otherwise.
