Privacy details

Visiting this site: your IP address is only used to deliver the page and is not logged (Art. 6(1)(f) GDPR).

When you send this form, your name, email address and message are emailed to me. Providing them is voluntary, but without an email address I can't reply. I only use them to answer you and don't pass them on, except to the service providers named here or where the law requires it. I keep your message in my mailbox for as long as needed to answer it.

This site and the form run on servers I operate in Germany, one of them rented from netcup GmbH, Karlsruhe. Until the email is sent, your message waits in a queue there. It is deleted as soon as it has been delivered, or after 24 hours if delivery keeps failing, and purged from the server's disk within the following hour. Your IP address is not stored. My mailbox is hosted by Purelymail (Add Rabbit LLC, Erie, Pennsylvania, USA), so your message is transferred to the USA; the transfer is necessary to answer your request (Art. 49(1)(b) GDPR).

You will usually receive an automatic confirmation by email. To prevent misuse, a keyed hash of your email address is kept for 24 hours, so that at most one confirmation per address is sent per day. Before sending, your browser solves a small computational puzzle that keeps spam bots out; only the puzzle and its solution are exchanged with my server.

The legal basis for answering you is Art. 6(1)(b) GDPR where your request concerns a contract and Art. 6(1)(f) GDPR otherwise; spam and abuse protection is based on Art. 6(1)(f) GDPR. You have the right to access, rectification, erasure, restriction of processing and data portability (Art. 15–20 GDPR) and may lodge a complaint with a data protection supervisory authority.

You may object at any time to processing based on Art. 6(1)(f) GDPR (Art. 21 GDPR).
