Controller

Christoph Bauer, address and contact as in the legal notice.

What these pages do not do

no cookies, no local storage for advertising
no trackers, no analytics, no ad networks
no fonts, scripts or images from foreign servers — xterm.js is vendored in this repository with its checksum
no contact forms, so no submitted data either

What does happen

The web server (nginx on a self-hosted NixOS machine) writes the usual access logs; they contain technical details of each request, including the IP address. The purpose is operation and troubleshooting. All connections are TLS encrypted.

The pages /pi/ and /e/ compute their digits entirely inside the visitor's browser, in a Web Worker. No data is sent to the server.

Your rights

The rights under the GDPR apply (information, rectification, erasure, restriction, data portability, objection), as does the right to complain to a supervisory authority. [Placeholder: Chris adds a fuller statement if he wants one.]
