+## No User Agent and Referrer
+
+At least for now I don't need it for debugging purposes. This may change in the future.
+
+## No Cookies
+
+Cookies will not be set on these sites. I configured [nginx](https://nginx.org) to drop the header „Set-Cookie“ `proxy_hide_header Set-Cookie;`.
+
+## No Tracking and Analytics
+
+I don't track you, I don't collect data for analytics, I have no use for it. And I don't want to be tracked or analyzed either.
