# Privacy

This is the personal website of Dieter Wiesner at https://www.dieterwiesner.com/. It is a public dossier. It is not an account product, a shop checkout, or a comment forum.

## What we collect

The site itself does not run a first-party analytics tag, does not embed third-party advertising pixels, and does not offer user accounts. A visitor file serial may be stored in the browser's localStorage (`dw-file-serial`) so the cinematic homepage can label a session. That value never leaves the browser through any form we publish.

If you write to DW@DieterWiesner.com, we receive whatever you put in the message: name, organisation, and the facts of the request. Email is handled as correspondence, not as a marketing list.

## Infrastructure

The site is served from Cloudflare Pages. Cloudflare may process technical request data (IP address, user-agent, TLS metadata, bot score, standard server logs) to deliver the pages and to absorb abuse. Cloudflare may set a security cookie such as `__cf_bm` when bot mitigation is active. We do not sell that data and we do not use it to build advertising profiles.

## What we do not do

We do not sell personal data. We do not run on-site payment forms. We do not require a cookie banner for first-party advertising, because there is none. External buy links (publisher, Amazon) are their own controllers. Social links leave this host.

## Rights and contact

If you want a copy, correction, or deletion of correspondence you sent, write to DW@DieterWiesner.com with the subject "Privacy". Name the message and the date as well as you can. For a legal privacy demand, name your counsel.
