Analytics. This site runs its own Umami instance on the same server, with no cookies and no cross-site tracking. What is stored is an aggregated page view: page, referrer, country, browser family, screen size. No IP address is kept, no profile is built, and no analytics data is shared with third parties.
Newsletter. If you subscribe, your email address is stored only to send the newsletter. Every email has an unsubscribe link; unsubscribing deletes the address.
Affiliate links. Clicking an affiliate link sends you to the provider, who sets their own cookies under their own privacy policy. See the affiliate disclosure.
Hosting. The site runs on a server in Germany (Hetzner). Web server access logs are kept for a short period for security and are not used for analytics.
