Newsletter & Email Delivery (EmailOctopus) Copy link to this section
I manage my mailing list with EmailOctopus, run by Three Hearts Digital Ltd (London, UK), which also delivers the emails.
- Data Transfer: When you sign up, your email address and first name are sent to EmailOctopus through a Cloudflare Worker on this site. Subscriber data is stored on AWS servers in Ireland.
- Compliance: Data is processed under a Data Processing Agreement (DPA) included in their Terms of Service.
- Tracking: To improve my content, I track if emails are opened or links are clicked. You can opt-out by unsubscribing.
Technical Infrastructure (Cloudflare) Copy link to this section
This site is hosted on Cloudflare Pages. Cloudflare acts as a protective layer, processing your IP address to defend against attacks and optimize delivery. They may use strictly necessary cookies (e.g., __cf_bm) for bot detection.
Analytics (Umami Cloud) Copy link to this section
I use cookieless Umami Analytics, hosted by Umami Cloud. It does not track individuals or store PII.
Fonts (Google Fonts) Copy link to this section
Typefaces on this site are loaded from Google Fonts. Your browser requests the font files directly from Google’s servers, which means Google receives your IP address and browser metadata when a page loads.
4. International Transfers Copy link to this section
While my primary contact details are in Poland, services like Cloudflare, Umami Cloud or Google may process data in the USA. These transfers are governed by the EU-U.S. Data Privacy Framework or Standard Contractual Clauses (SCCs).
