The controller responsible for this website under the EU General Data Protection Regulation (GDPR) is Henry Gressmann. Contact information is available in the Impressum/Legal Notice .
This is a private website and blog. I process personal data only where it
is necessary to provide this website, keep it secure, respond to messages,
or understand basic, privacy-friendly usage statistics. I do not sell
personal data.
This website does not intentionally set tracking cookies. If this changes, this
privacy policy will be updated accordingly.
As a data subject, you have the right of access, rectification, erasure,
restriction of processing, data portability, and objection to processing
of your personal data. If processing is based on consent, you may withdraw
that consent at any time with effect for the future.
Please send requests, objections, or withdrawals informally to:
contact@henrygressmann.de .
You may at any time lodge a complaint with a supervisory authority, e.g. the
competent supervisory authority in the federal state of your residence or the
authority responsible for me as the controller.
A list of supervisory authorities (for the non-public sector) with address can
be found at

.
If you contact me by email, I process the data you provide, such as your
email address, name, message content, and technical metadata, to respond
to your request. The legal basis is Art. 6 para. 1 lit. f GDPR. If your
message relates to a contractual or pre-contractual matter, the legal
basis may also be Art. 6 para. 1 lit. b GDPR.
I keep email correspondence only as long as necessary for the relevant purpose,
unless legal retention obligations apply.
The meeting page embeds Cal.com. When you visit that page or schedule a
meeting, personal data such as your IP address, browser information, name,
email address, selected time, and message content may be processed by
Cal.com. This is used to provide scheduling functionality. The legal basis
is Art. 6 para. 1 lit. f GDPR, and where scheduling concerns a contractual
or pre-contractual request, Art. 6 para. 1 lit. b GDPR.

This website uses a privacy-friendly analytics. The analytics are used to
understand basic usage of this website and improve its content and
technical performance. The legal basis is my legitimate interest under
Art. 6 para. 1 lit. f GDPR.
Analytics data is processed in anonymized or aggregated form. I do not use the
analytics setup to create personal profiles, track visitors across third-party
websites, or store persistent personal identifiers. No analytics cookies are
intentionally set by this website.
To deliver this website, technical access data may be processed in server
log files. This can include your IP address, date and time of the request,
requested URL, referrer, HTTP status code, amount of data transferred, and
information about the browser and operating system. This processing is
necessary to display the website and ensure stability, performance, and
security. The legal basis is Art. 6 para. 1 lit. f GDPR.
I use the following providers to make this website available:
Industriestr. 25, 91710 Gunzenhausen
www.hetzner.com/de/rechtliches/datenschutz
GitHub, Inc., 88 Colin P Kelly Jr St, San Francisco, CA 94107, USA. GitHub
Pages may be used to host static files such as images, fonts, JavaScript,
and documents. GitHub may process technical access data for this purpose.
This is in line with my legitimate interest under Art. 6 para. 1 lit. f
GDPR, so that I do not have to operate all infrastructure myself. The
server location may be the USA. For further information on how to object
or remove data on GitHub, you can check:
docs.github.com/en/github/site-policy/github-privacy-statement
You have the right to object to this processing. Whether the objection is successful
needs to be determined through a balancing of interests. The data will be deleted
as soon as the purpose of its processing has been fulfilled, unless legal retention
obligations apply. Processing of the data specified in this section is neither
legally nor contractually required. However, the functionality of the website
is not guaranteed without this processing. GitHub has implemented compliance
measures for international data transfers, including EU Standard Contractual
Clauses (SCCs). More info can be found at:

Cloudflare Germany GmbH, Rosental 7, c/o Mindspace, 80331 München, Germany (Cloudflare)
I use the Content Delivery Network (CDN) provided by Cloudflare to enhance
the security and delivery speed of this website. This aligns with my
legitimate interest (Art. 6 para. 1 lit. f GDPR). A CDN is a network of
globally distributed servers capable of delivering optimized content to
website users. For this purpose, personal data may be processed in
Cloudflare's server log files. Please refer to the "Hosting" section for
more details.
Cloudflare acts as a recipient of your personal data and serves as a processor
on my behalf. This is also in line with my legitimate interest under Art. 6
para. 1 lit. f GDPR, as it allows me to not operate a CDN myself.
You have the right to object to the processing. Whether the objection is successful
will be determined through a balance of interests assessment.
The processing of data specified in this section is neither legally nor contractually
required. However, the functionality of the website cannot be guaranteed without
this processing.
Your personal data will be stored by Cloudflare for as long as necessary for
the stated purposes.

refer to:
